AsyncTask异步实现(方便自己后续复习)

public class Main extends Activity {

	private LayoutInflater m_flater = null;
	private LinearLayout mFlash;

	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.flash);
		mFlash = (LinearLayout) findViewById(R.id.mFlash);
		mFlash.startAnimation(AnimationUtils
				.loadAnimation(this, R.anim.fadeout));
		m_flater = getLayoutInflater();
		LoadMainTask task = new LoadMainTask(this);
		task.execute("");

	}

	public View LoadMainView(LayoutInflater flater) {
		View view = flater.inflate(R.layout.main, null);
		Button btnOk = (Button) view.findViewById(R.id.BtnOk);
		btnOk.setOnClickListener(new OnClickListener() {
			public void onClick(View v) {
				finish();
			}
		});
		return view;
	}

	private class LoadMainTask extends AsyncTask<Object, Object, View> {
		public LoadMainTask(Context context) {
		}

		protected View doInBackground(Object... params) {
			View view = null;
			view = LoadMainView(m_flater);
			// 为了测试加了延时，大家可以在这一块加载资源，数据等
			try {
				Thread.sleep(3000);
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
			return view;
		}

		// 执行完毕
		protected void onPostExecute(View view) {
			setContentView(view);
		}
	}

}
