CheckBox复选框用法，先看效果图
选择点击按钮后，会在标题栏显示选中的项。
main.xml代码：
<CheckBox android:id="@+id/box1"
android:text="我是BOX1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<CheckBox android:id="@+id/box2"
android:text="我是BOX2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<Button android:id="@+id/b1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="按我"
/>
主程序代码:
package com.pocketdigi;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.CheckBox;
public class main extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
boxDemo();
}
CheckBox box1;
CheckBox box2;
private void boxDemo(){
box1=(CheckBox)findViewById(R.id.box1);
box2=(CheckBox)findViewById(R.id.box2);
Button b1=(Button)findViewById(R.id.b1);
b1.setOnClickListener(Dialog);
}
private Button.OnClickListener Dialog=new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
String s="";
if(box1.isChecked()){
s+="box1,";
}
if(box2.isChecked()){
s+="box2";
}
setTitle(s);
}
};
}
