我面临一个非常烦人的情况 . 我正在尝试使用DatePicker和TimePicker显示警告对话框 . 除了一些三星设备外，它适用于所有设备（根据我收到的崩溃报告，所有这些都是Android版本6.0.1） .
这是崩溃报告：

CUSTOM_DATA=
PHONE_MODEL=SAMSUNG-SM-T377A
BRAND=samsung
ANDROID_VERSION=6.0.1
APP_VERSION_NAME=3.1.0
这是我的代码：
public void askTimestamp(final String transaction_type, final String item_name, final int integerItems, final EditText item_count, final int newItemCount, final TextView textBox_count)
{
final AlertDialog.Builder dialog = new AlertDialog.Builder(this);
dialog.setTitle("Enter Transaction Details");
View view = getLayoutInflater().inflate(R.layout.dialog_date_time, null);
final CustomDatePicker datePicker = (CustomDatePicker) view.findViewById(R.id.datePicker);
final TimePicker timePicker = (TimePicker) view.findViewById(R.id.timePicker);
dialog.setView(view);
dialog.setPositiveButton(getString(R.string.done), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
String day = "";
String month = "";
String year = "";
String hours = "";
String minutes = "";
String seconds = "00";
day = datePicker.getDayOfMonth() + "";
if (day.length() == 1)
{
day = "0" + day;
}
int actualMonth = datePicker.getMonth() + 1;
month = actualMonth + "";
if (month.length() == 1)
{
month = "0" + month;
}
year = datePicker.getYear() + "";
if (year.length() == 3)
{
year = "0" + year;
}
else if(year.length() == 2)
{
year = "00" + year;
}
else if(year.length() == 1)
{
year = "000" + year;
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
{
hours = timePicker.getHour() + "";
minutes = timePicker.getMinute() + "";
}
else
{
hours = timePicker.getCurrentHour() + "";
minutes = timePicker.getCurrentMinute() + "";
}
if (hours.length() == 1)
{
hours = "0" + hours;
}
if (minutes.length() == 1)
{
minutes = "0" + minutes;
}
String dateTime = year + "-" + month + "-" + day + " " + hours + ":" + minutes + ":" + seconds;
dbHelper.updateItem(item_name, newItemCount);
dbHelper.createTransaction(transaction_type, item_name, integerItems, dateTime);
if (transaction_type.equals("add"))
{
Toast.makeText(MyApp.getContext(), getString(R.string.transaction_adding) + " " + item_name.trim() + " " + getString(R.string.succeeded) + "!", Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(MyApp.getContext(), getString(R.string.transaction_removing) + " " + item_name.trim() + " " + getString(R.string.succeeded) + "!", Toast.LENGTH_SHORT).show();
}
item_count.setText("");
textBox_count.setText(newItemCount + "");
dialog.cancel();
}
});
dialog.setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id)
{
// User cancelled the dialog
dialog.dismiss();
}
});
AlertDialog dialog_created = dialog.create();
if (!this.isFinishing())
{
dialog_created.show();
}
}
这是我试图膨胀的布局：
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ankit.inventory.ankitarora.inventorymanagementsimple.CustomDatePicker
android:id="@+id/datePicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:theme="@android:style/Theme.Holo.Light" >
</ankit.inventory.ankitarora.inventorymanagementsimple.CustomDatePicker>
<TimePicker
android:id="@+id/timePicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/datePicker"
android:scrollbars="vertical"
android:theme="@android:style/Theme.Holo.Light" >
</TimePicker>
</RelativeLayout>
请帮忙！
