Android recipe 新的设置onClick监听器的方法

注意，这个方法只支持API level4以上。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
    <Button
        android:id="@+id/button"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:onClick="onMyClick" />
</LinearLayout>

　　

package my.demo;

import android.app.Activity;

public class TempActivity extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
    
    public void onMyClick(View v) {
        switch (v.getId()) {
        case R.id.button:
            ((TextView) findViewById(R.id.text)).setText("被点击！");
            break;
        }
    }
}
