Question

我想检测具有特定布局的onLongPress事件。在我的xL LinearLayout中，在RelativeLayout中。我想只在LinearLayout中获取onLongTouch。我尝试使用onTouchEvent这很好用，但onLongPress工作在孔布局上包括RelativeLayout。如果我将return mDetector.onTouchEvent(event);放在myLinear.setOnTouchListener中。它会变成单个Touch.Please帮我解决这个问题。任何回复我都非常感谢。

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent"
android:layout_height="match_parent" 
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MainActivity">

<TextView
    android:id="@+id/txtView"
    android:layout_width="wrap_content"
    android:text="Show Text"
    android:textStyle="bold"
    android:textSize="@dimen/abc_text_size_title_material"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true" />

<LinearLayout
    android:id="@+id/myLinear"
    android:layout_below="@+id/txtView"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/floorimg">

</LinearLayout>

MainActivity.java

public class MainActivity extends AppCompatActivity {

LinearLayout myLinear;
private GestureDetectorCompat mDetector;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    myLinear = (LinearLayout)findViewById(R.id.myLinear);
    mDetector = new GestureDetectorCompat(this, new MyGestureListener());

    myLinear.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return mDetector.onTouchEvent(event);
        }
    });

}

/* @Override
public boolean onTouchEvent(MotionEvent ev) {
    super.onTouchEvent(ev);
    return mDetector.onTouchEvent(ev);
}*/

private class MyGestureListener extends GestureDetector.SimpleOnGestureListener {
    @Override
    public void onLongPress(MotionEvent e) {
        Toast.makeText(getBaseContext(),"Long press called",Toast.LENGTH_SHORT).show();
        super.onLongPress(e);
    }
}

}

您可能希望将OnLongClickListener与LinearLayout一起使用：

myLinear.setOnLongClickListener(new View.OnLongClickListener() {
    @Override
    public boolean onLongClick(View v) {
        Toast.makeText(getBaseContext(), "Long press called", Toast.LENGTH_SHORT).show();
        return true;
    }
});

在android中特定的LinearLayout中检测onLongPress？
