in android I would like to get/return the cursor location (lattitude and langitude) when i click anywhere on the screen . Can any one help me..?

推荐答案

我不知道你想获得lattitude和langitude什么，但我相信你可以得到cordinates的位置 X和Y 当用户触摸屏幕。

I don't know for what you want to get lattitude and langitude but I am sure you can get the position of the cordinates X and Y when a user touch the screen.

实施 OnTouchListener 在活动，并设置监听器你的浏览使用 setOnTouchListener（）方法。

Implement OnTouchListener in your Activity and set the Listener for your View using the setOnTouchListener() method.

现在我们可以覆盖在你的活动的 onTouch（）方法。

Now you can override the onTouch() method in your Activity.

@Override
public boolean onTouch(View view, MotionEvent event) {
    int x = (int) event.getX();       
    int y = (int) event.getY();
    return false;
}

请参阅我写了一个示例代码段为你：

See I have written a sample snippet for you:

    public class OnTouchDemo extends Activity implements OnTouchListener {

    private TextView tView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        tView = (TextView) findViewById(R.id.txtView1);
        tView.setOnTouchListener(this);
    }

    @Override
    public boolean onTouch(View view, MotionEvent event) {
        int x = (int) event.getX();
        int y = (int) event.getY();

        Log.v("OnTouchDemo", "X==" + String.valueOf(x) + " Y==" + String.valueOf(y));

        return false;
    }
}
