Java 在android中仅检测长按特定线性布局?_Java_Android_Xml_Android Layout - Fatal编程技术网

Java 在android中仅检测长按特定线性布局?

Java 在android中仅检测长按特定线性布局?,java,android,xml,android-layout,Java,Android,Xml,Android Layout,我想检测具有特定布局的onLongPress事件。在我的xml LinearLayout中,使用RelativeLayout。我只想在LinearLayout中获得onLongTouch。我尝试使用onTouchEvent,这很好,但onLongPress处理孔布局,包括RelativeLayout。如果我放置返回mDetector.onTouchEvent(事件)在myLinear.setOnTouchListener中使用。它将变成单触式。请帮助我解决此问题。任何回复我都非常感谢 activ

您可能希望与线性布局一起使用:

myLinear.setOnLongClickListener(新视图.OnLongClickListener(){
@凌驾
仅长按公共布尔值(视图v){
Toast.makeText(getBaseContext(),“长按调用”,Toast.LENGTH_SHORT.show();
返回true;
}
});

Bro正是我想要放大线性布局并添加多个pinmark。所以我问了这个问题。我已经试过了。首先,我们得到x和y坐标,然后加上细记号。onLongClickListener只能在布局上调用一次。是否可以引用其他选项?
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);
    }
}

}
