Android的 - 手势检测（刷卡向上/向下）的特定视图 [英] Android - Gesture Detection (Swipe up/down) on particular view

问题描述

我想实现在Android上OnGestureListener。
我有三个TextViews在我的布局。
什么，我想实现的是设置手势侦听器两个textViews的。
这是在布局 -

I am trying to implement the OnGestureListener in Android.
I have three TextViews in my layout.
What i am trying to achieve is to set Gesture Listener for two of the textViews .
Here is the layout -

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rlMain"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >

<TextView
    android:id="@+id/tvOne"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="10dp"
    android:layout_marginTop="5dp"
    android:gravity="center"
    android:text="One" />

<TextView
    android:id="@+id/tvTwo"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/tvOne"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="10dp"
    android:layout_marginTop="5dp"
    android:gravity="center"
    android:text="Two" />

<TextView
    android:id="@+id/tvThree"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/tvTwo"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="10dp"
    android:layout_marginTop="5dp"
    android:gravity="center"
    android:text="Three" />

这里是在活动 -

And here is the activity -

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.GestureDetector;
import android.view.GestureDetector.OnGestureListener;
import android.view.MotionEvent;

public class TimeActivity extends Activity implements OnGestureListener {

GestureDetector gestureScanner;

@SuppressWarnings("deprecation")
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.wheelview);
    gestureScanner = new GestureDetector(this);

}

@Override
public boolean onTouchEvent(MotionEvent event) {
    // TODO Auto-generated method stub
    return gestureScanner.onTouchEvent(event);
}

@Override
public boolean onDown(MotionEvent e) {
    // TODO Auto-generated method stub
    return true;
}

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
        float velocityY) {
    // TODO Auto-generated method stub
    Log.i("Test", "On Fling");
    return true;
}

@Override
public void onLongPress(MotionEvent e) {
    // TODO Auto-generated method stub

}

@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
        float distanceY) {
    // TODO Auto-generated method stub
    return false;
}

@Override
public void onShowPress(MotionEvent e) {
    // TODO Auto-generated method stub

}

@Override
public boolean onSingleTapUp(MotionEvent e) {
    // TODO Auto-generated method stub
    return false;
}

}

在present一扔了所有三个textviews获取调用。
有没有什么办法，通过它我可以设置在手势监听器在布局一些特定的观点。
任何帮助将是非常美联社preciated。

At present Fling for all the three textviews is getting called .
Is there any way through which i can set the Gesture Listener for some particular views in the layout.
Any help will be highly appreciated.

推荐答案

在的onCreate 办法做到这一点。

findViewById(R.id.tvOne).setOnTouchListener(new View.OnTouchListener() { 
            @Override
           public boolean onTouch(View v, MotionEvent event){
                return gestureScanner.onTouchEvent(event);
           }
  });
