Android:焦点在EditText上时自动显示软键盘

提问于

我正在使用 AlertDialog 显示一个输入框 . 当我调用 AlertDialog.show() 时,对话框内的 EditText 会自动聚焦,但软键盘不会自动显示 .

如何在显示对话框时自动显示软键盘? (并且没有物理/硬件键盘) . 与按下“搜索”按钮调用全局搜索的方式类似,将自动显示软键盘 .

    您可以在 AlertDialog 上的 EditText 上创建焦点侦听器,然后获取 AlertDialogWindow . 从那里你可以通过调用 setSoftInputMode 来制作软键盘 .

    final AlertDialog dialog = ...;
    
    editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
                dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
            }
        }
    });

    用于显示键盘用途:

    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
    

    隐藏键盘使用:

    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(view.getWindowToken(),0);

    您可以在创建对话框后立即请求软键盘(在SDK上测试 - r20)

    // create dialog
    final AlertDialog dialog = ...; 
    
    // request keyboard   
    dialog.getWindow().setSoftInputMode (WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

    我有同样的问题,并用以下代码解决了它 . 我不确定它在具有硬件键盘的手机上的表现如何 .

    // TextEdit
    final EditText textEdit = new EditText(this);
    
    // Builder
    AlertDialog.Builder alert = new AlertDialog.Builder(this);
    alert.setTitle("Enter text");
    alert.setView(textEdit);
    
    alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            String text = textEdit.getText().toString();
            finish();
        }
    });
    
    alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            finish();
        }
    });
    
    // Dialog
    AlertDialog dialog = alert.create();
    dialog.setOnShowListener(new OnShowListener() {
    
        @Override
        public void onShow(DialogInterface dialog) {
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.showSoftInput(textEdit, InputMethodManager.SHOW_IMPLICIT);
        }
    });
    
    dialog.show();

    我找到了这个例子http://android-codes-examples.blogspot.com/2011/11/show-or-hide-soft-keyboard-on-opening.html . 在 alert.show() 之前添加以下代码 .

    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);

    <activity
        ...
        android:windowSoftInputMode="stateVisible" >
    </activity>
    

    要么

    getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

    来自其他答案的代码片段可以正常工作,但在代码中放置它们并不总是很明显,特别是如果您使用的是 AlertDialog.Builder 并且遵循official dialog tutorial,因为它不使用 final AlertDialog ...alertDialog.show() .

    alertDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
    

    比较好

    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
    

    因为如果焦点从EditText切换,SOFT_INPUT_STATE_ALWAYS_VISIBLE将隐藏键盘,其中SHOW_FORCED将保持键盘显示直到它被明确解除,即使用户返回主屏幕或显示最近的应用程序 .

    下面是使用自定义布局创建的AlertDialog的工作代码,其中EditText是用XML定义的 . 它还将键盘设置为具有“go”键并允许其触发正按钮 .

    alert_dialog.xml:

    <RelativeLayout
    android:id="@+id/dialogRelativeLayout"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >
    
        <!-- android:imeOptions="actionGo" sets the keyboard to have a "go" key instead of a "new line" key. -->
        <!-- android:inputType="textUri" disables spell check in the EditText and changes the "go" key from a check mark to an arrow. -->
        <EditText
            android:id="@+id/editText"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="16dp"
            android:layout_marginLeft="4dp"
            android:layout_marginRight="4dp"
            android:layout_marginBottom="16dp"
            android:imeOptions="actionGo"
            android:inputType="textUri"/>
    
    </RelativeLayout>

    嗯,这是一个相当古老的帖子,还有一些东西需要补充 .
    这些是两种简单的方法,可以帮助我控制键盘,它们的工作非常完美:

    Show keyboard

    public void showKeyboard() {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        View v = getCurrentFocus();
        if (v != null)
            imm.showSoftInput(v, 0);
    }
    

    Hide keyboard

    public void hideKeyboard() {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        View v = getCurrentFocus();
        if (v != null)
            imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
    }

    让我指出一些额外的信息到yuku的解决方案,因为我发现很难让这个工作!如何从AlertDialog.Builder获取AlertDialog对象?嗯,这是我 alert.show() 执行的结果:

    final AlertDialog.Builder alert = new AlertDialog.Builder(getActivity());
    final EditText input = new EditText(getActivity());
    alert.setView(input);
    
    // do what you need, like setting positive and negative buttons...
    
    final AlertDialog dialog = alert.show();
    
    input.setOnFocusChangeListener(new OnFocusChangeListener() {
       @Override
       public void onFocusChange(View v, boolean hasFocus) {
          if(hasFocus) {
             dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
          }
       }
    });

    看一下处理手动隐藏和显示IME的this讨论 . 但是,我的感觉是,如果一个专注的 EditText 没有带来IME,那是因为你在你的_1151609中调用了 AlertDialog.show() 或者在实际呈现屏幕之前引发的其他一些方法 . 把它移到 OnPostResume() 应该修复它,我相信 .

    是的,你可以用 setOnFocusChangeListener 它会帮助你 .

    editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
                dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
            }
        }
    });

    如果有人得到:

    无法从类型Activity中对非静态方法getSystemService(String)进行静态引用

    尝试将 context 添加到getSystemService调用 .

    所以

    InputMethodManager imm = 
    (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);

    最初的问题涉及Dialogs和我的EditText是常规视图 . 无论如何,我怀疑这对大多数人来说也应该有效 . 所以这对我有用(上面提出的评价最高的方法对我没有任何帮助) . 这是一个自定义的EditView来执行此操作(子类化不是必需的,但我发现它很方便我的目的,因为我想在视图变得可见时 grab 焦点) .

    这实际上与tidbecks答案大致相同 . 实际上我没有注意到他的回答,因为它的票数为零 . 然后我就要评论他的帖子了,但这太长了,所以无论如何我都结束了这个帖子 . tidbeck指出,他不确定如何使用键盘设备 . 我可以确认在任何一种情况下行为似乎完全相同 . 这样,在纵向模式下,软件键盘会弹出,而在横向上则不会 . 物理键盘滑出或没有在我的手机上没有任何区别 .

    因为,我个人发现我选择使用的行为有点尴尬: InputMethodManager.SHOW_FORCED . 这是我希望它工作的工作原理 . 无论方向如何,键盘都会变得可见,但是,如果硬件键盘滑出,至少在我的设备上它不会弹出 .

    问题似乎是,因为您输入文本的地方是隐藏最初(或嵌套或某事),AlertDialog自动设置标志 WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IMWindowManager.LayoutParams.FLAG_NOT_FOCUSABLE ,以便事物不会触发显示的软输入 .

    解决此问题的方法是添加以下内容:

    (...)
    // Create the dialog and show it
    Dialog dialog = builder.create()
    dialog.show();
    
    // After show (this is important specially if you have a list, a pager or other view that uses a adapter), clear the flags and set the soft input mode
    dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
    dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

    尝试并使用:

    editText.requestFocus();
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);

    为了显示键盘,对我来说,我必须做以下事情

    Android TextField : set focus + soft input programmatically

    基本上解决方案如下

    @Override
    public void onResume() {
        super.onResume();
        //passwordInput.requestFocus(); <-- that doesn't work
        passwordInput.postDelayed(new ShowKeyboard(), 325); //250 sometimes doesn't run if returning from LockScreen
    }
    

    ShowKeyboard 在哪里

    private class ShowKeyboard implements Runnable {
        @Override
        public void run() {
            passwordInput.setFocusableInTouchMode(true);
            //passwordInput.requestFocusFromTouch(); //this gives touch event to launcher in background -_-
            passwordInput.requestFocus();
            getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
            ((InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE)).showSoftInput(passwordInput, 0);
        }
    }
    

    输入成功后,我也确保隐藏键盘

    getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
    ((InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE))
                        .hideSoftInputFromWindow(getView().getWindowToken(), 0);

    我创建了很好的kotlin-esqe扩展功能,任何人都有兴趣

    fun Activity.hideKeyBoard() {
        val view = this.currentFocus
        val methodManager = this.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        assert(view != null)
        methodManager.hideSoftInputFromWindow(view!!.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
    }
    
    fun Activity.showKeyboard() {
        val view = this.currentFocus
        val methodManager = this.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        assert(view != null)
        methodManager.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT)
    }

    为什么这个答案 - 因为上面的解决方案将显示你的键盘,但如果你点击 EditText 之外的任何地方它也不会消失 . 因此,当_1151629失去焦点时,你需要做一些事情来使keybaord消失 .

    您可以通过执行以下步骤来实现此目的:

    • 通过添加以下属性,使父视图(活动的内容视图)可单击并可聚焦
    android:clickable="true" 
        android:focusableInTouchMode="true"
    
    • 实现hideKeyboard()方法
    public void hideKeyboard(View view) {
            InputMethodManager inputMethodManager =(InputMethodManager)getSystemService(Activity.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(),InputMethodManager.HIDE_IMPLICIT_ONLY );
        }
    
    • 最后,设置edittext的onFocusChangeListener .
    edittext.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (!hasFocus) {
                    hideKeyboard(v);
                }
            }
        });

    这有点棘手 . 我这样做了,它起作用了 .

    1.首先调用以隐藏窗口中的软输入 . 如果软键盘可见,这将隐藏软输入,如果不可见则不执行任何操作 .

    2.显示你的对话

    3.然后简单地调用切换软输入 .

    码:

    InputMethodManager inputManager = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); 
    //hiding soft input

    试试这个

    SomeUtils.java public static void showKeyboard(Activity activity,boolean show){
    InputMethodManager inputMethodManager =(InputMethodManager)activity.getSystemService(Context.INPUT_METHOD_SERVICE);

    如果(显示)
    inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
    其他
    inputMethodManager.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY,0);
    }

    将这些方法放在Util类中并在任何地方使用 .

    科特林

    fun hideKeyboard(activity: Activity) {
        val view = activity.currentFocus
        val methodManager = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        assert(view != null)
        methodManager.hideSoftInputFromWindow(view!!.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
    }
    
    private fun showKeyboard(activity: Activity) {
        val view = activity.currentFocus
        val methodManager = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        assert(view != null)
        methodManager.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT)
    }
    

    Java

    public static void hideKeyboard(Activity activity) {
        View view = activity.getCurrentFocus();
        InputMethodManager methodManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
        assert methodManager != null && view != null;
        methodManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
    }
    
    private static void showKeyboard(Activity activity) {
        View view = activity.getCurrentFocus();
        InputMethodManager methodManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
        assert methodManager != null && view != null;
        methodManager.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT);
    }

    正如horkavlna所写,

    切换

    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
    

    并隐藏键盘

    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
    

    方法工作 . 但展示变体在我的情况下不起作用 . 所以在 onCreate() 我把 hideKeyboard(editText); 然后放在 onStart() 我写 toggleKeyboard(editText); 并在 onStop() 我写 hideKeyboard(editText); .

    有三个问题:

    1)当应用程序以关闭屏幕启动时,它将隐藏键盘,

    2)每次打开屏幕,它都会显示键盘,

    3)应用完成后,您可以在Android主屏幕中看到键盘 .

    经过多次测试后,我删除了这些方法并在 AndroidManifestactivity 标签写了 android:windowSoftInputMode="stateVisible"android:windowSoftInputMode="stateAlwaysHidden" .

    getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
    

    当我进入Activity时,我在onCreate()中调用它来自动显示键盘 .
