AsyncTask异步实现

Java代码  

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);
        }
    }

}
