android – 应用程序崩溃与“从错误的线程异常”

我在我的onCreate()方法中添加了这部分代码,并且它崩溃了我的应用程序.
需要帮忙.

logcat的：

android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread 
that created a view hierarchy can touch its views.

码：

final TextView timerdisplayPanel = (TextView) findViewById(R.id.textView2);

    Timer t = new Timer();
    t.schedule(new TimerTask(){
        public void run(){
            timerInt++;
            Log.d("timer","timer");
            timerdisplayPanel.setText("Time ="+ timerInt +"Sec");
        }
    },10,1000);

解决方法

Only the original thread that created a view hierarchy can touch its views.

您正在尝试更改非UI线程中UI元素的文本,因此它将异常.使用runOnUiThread

t.schedule(new TimerTask() {
public void run() {
    timerInt++;
    Log.d("timer","timer");
    runOnUiThread(new Runnable() {

    @Override
    public void run() {
              timerdisplayPanel.setText("Time =" + timerInt + "Sec");
            }
    });
        }
    },1000);
