安卓控件4

进度条
ProgressBar
style=”?android:attr/progressBarStyleHorizontal”
这是进度条的样式
贴上Java代码

Handler handler=new Handler(){
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
int i=msg.what;
textView.setText(i+”“);
}
};

class Main2 extends Thread{    @Override    public void run() {        super.run();        for (int i = 0; i <=100 ; i++) {            progressbar.setProgress(i);            //textView.setText(i+"");            handler.sendEmptyMessage(i);            try {                Thread.sleep(100);            } catch (InterruptedException e) {                e.printStackTrace();            }        }    }

多个单选按钮切换

给每一个按钮设置点击事件
然后在Java代码哪里用map接受
