关于Thread，Handler和ProgressBar的简单使用（二）

用Thread和Handler控制ProgressBar的进度
public class HandlerProgressBarAty extends Activity{



private int i = 0;

private ProgressBar mProgressBar;



private android.os.Handler mHandler = new Handler(){

@Override

public void handleMessage(Message msg) {

mHandler.postDelayed(mThread, 1000);

}

};



@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.pb);

mProgressBar = (ProgressBar) findViewById(R.id.pb);

Button btn_download = (Button) findViewById(R.id.btn_download);

btn_download.setOnClickListener(new View.OnClickListener() {



@Override

public void onClick(View v) {

mProgressBar.setVisibility(View.VISIBLE);

mHandler.post(mThread);

}

});

}



private Thread mThread = new Thread(new Runnable(){


@Override

public void run() {

i = i + 10;

mProgressBar.setProgress(i);

Message msg = mHandler.obtainMessage();

msg.arg1 = i;

mHandler.sendMessage(msg);

if(i > 100){

mHandler.removeCallbacks(mThread);

}

}



});

}
