Question

对于三星设备的 EditText 中的任何onLongPress / onDoubleClick，该应用都会崩溃。但是，其他设备不会出现此问题。我正在使用旧的Note 2进行调试，并在论坛中发布类似的问题（但已被删除）。很棒，如果有人愿意分享解决方案。

<EditText
    android:id="@+id/vse_discountEv"
    android:hint="@string/vse_boradcastHint"            
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:paddingTop="@dimen/pad_3dp"
    android:paddingLeft="@dimen/pad_5dp"
    android:paddingRight="@dimen/pad_0dp"
    android:paddingBottom="@dimen/pad_5dp"              
    android:background="@color/transparent"
    android:textColorHint="@color/gray_main_light"
    android:textSize="@dimen/dim_20dp"
    android:scrollbars="horizontal" />

您是如何处理代码中的onLongPress和onDoubleClick的？

我在另一个三星设备（SM-A7009）中测试过以下代码，但遗憾的是找不到您所描述的问题。

我使用GestureDetector来处理onLongPress和onDoubleClick事件。

  EditText editText1 = new EditText(this);
  editText1.setText(R.string.app_name);
  final GestureDetectorCompat gestureDetectorCompat = new GestureDetectorCompat(this,
            new GestureDetector.SimpleOnGestureListener() {

                @Override
                public boolean onDown(MotionEvent e) {
                    return true;
                }

                @Override
                public void onLongPress(MotionEvent e) {
                    super.onLongPress(e);
                    Log.d(TAG, "onLongPress");
                }

                @Override
                public boolean onDoubleTap(MotionEvent e) {
                    Log.d(TAG, "onDoubleTap");
                    return super.onDoubleTap(e);
                }
            });
  editText1.setOnTouchListener(new View.OnTouchListener() {
      @Override
      public boolean onTouch(View v, MotionEvent event) {
          return gestureDetectorCompat.onTouchEvent(event);
      }
  });
  setContentView(editText1);
