Question

android 如何通过onTouchEvent（）方法来获取当前鼠标点击的坐标

请上例子！！！

Answer 1

public boolean onTouchEvent(android.view.MotionEvent event) {
int x = event.getX();
int y = event.getY();

多点触摸时 假如是第i个点
int x = event.getX(i);
int y = event.getY(i);

坐标就是 P(x,y)
}

追问

我是根据鼠标点击哪边 就取哪个的坐标啊

追答

我写的还不清楚？
int x = event.getX();
int y = event.getY();

追问

TMD 取不到坐标！！！

/*
*/
package test.test

import android.app.Activity;
import android.view.MotionEvent;

/**
*/
public class TestActivity extends Activity {
protected void onCreate(android.os.Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.id.main);
};

/**
* {@inheritDoc}
*/
@Override
public boolean onTouchEvent(MotionEvent event) {
float x = event.getX();
float y = event.getY();

System.out.println("坐标:" + x + "," + y);

return super.onTouchEvent(event);
}
}

屏幕上是个listview 取不到坐标

Answer 2

SharedPreferences share = getSharedPreferences("userPhoneNum",MODE_WORLD_WRITEABLE);

//可以
Editor edit = share.edit();
edit.putString("name", "dyc");
edit.putBoolean("flag", true);
edit.commit();
读成功！
System.out.println(share.getString("name", ""));
System.out.println(share.getBoolean("flag", false));

<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
<string name="name">dyc</string>
<boolean name="flag" value="true" />
</map>

Answer 3

public boolean onTouchEvent(android.view.MotionEvent event) {
int x = event.getX();
int y = event.getY();

多点触摸时 假如是第i个点
int x = event.getX(i);
int y = event.getY(i);

坐标就是 P(x,y)
}

Answer 4

MotionEvent中的方法：

getRowX：触摸点相对于屏幕的坐标
getX： 触摸点相对于按钮的坐标

Answer 5

mGallery.setOnTouchListener(new OnTouchListener(){

//@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction()==MotionEvent.ACTION_MOVE){
float x = event.getX();
float y = event.getY();

}
return false;
}

});
