Android基礎(chǔ)：在UI線程中運(yùn)行代碼從在UI線程中運(yùn)行代碼的角度來看，在以下方面有什么區(qū)別：MainActivity.this.runOnUiThread(new Runnable() {
public void run() {
Log.d("UI thread", "I am the UI thread");
}});或MainActivity.this.myView.post(new Runnable() {
public void run() {
Log.d("UI thread", "I am the UI thread");
}});和private class BackgroundTask extends AsyncTask<String, Void, Bitmap> {
protected void onPostExecute(Bitmap result) {
Log.d("UI thread", "I am the UI thread");
}}

它可以在沒有任何參數(shù)的情況下在任何地方使用：
new?Handler(Looper.getMainLooper()).post(new?Runnable()?{
????@Override
????public?void?run()?{
????????Log.d("UI?thread",?"I?am?the?UI?thread");
????}});
