如何在xml中直接添加view点击监听(参考rayleung博客)
文章分类:JavaEye
在Android1.6里面,添加Listener的工作变得相当的简单(感觉更像在做网页编程!),具体步骤如下:
1.main.xml文件
2. TestOnClickListener.java文件
1.main.xml文件
- <?xml version="1.0" encoding="utf-8"?>
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:orientation="vertical"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent"
- >
- <TextView
- android:layout_width="fill_parent"
- android:layout_height="wrap_content"
- android:text="@string/hello"
- />
- <Button
- android:text="Button01"
- android:id="@+id/Button01"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:onClick="myClickHandler"
- />
- </LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
<Button
android:text="Button01"
android:id="@+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="myClickHandler"
/>
</LinearLayout>
2. TestOnClickListener.java文件
- package com.ray.test;
- import android.app.Activity;
- import android.os.Bundle;
- import android.view.View;
- public class TestOnClickListener extends Activity {
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.main);
- }
- public void myClickHandler(View target){
- switch (target.getId()) {
- case R.id.Button01:
- setTitle("myButton01");
- break;
- }
- }
- }
