加载时Android显示启动画面

如果对于显示初始屏幕的时间没有特定限制，则可以通过

AsyncTask

public class SplashScreen extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_startup);        startHeavyProcessing();    }    private void startHeavyProcessing(){       new LongOperation().execute("");    }    private class LongOperation extends AsyncTask<String, Void, String> {        @Override        protected String doInBackground(String... params) { //some heavy processing resulting in a Data String for (int i = 0; i < 5; i++) {     try {         Thread.sleep(1000);     } catch (InterruptedException e) {         Thread.interrupted();     } } return "whatever result you have";        }        @Override        protected void onPostExecute(String result) { Intent i = new Intent(SplashScreen.this, MainActivity.class); i.putExtra("data", result); startActivity(i); finish();        }        @Override        protected void onPreExecute() {}        @Override        protected void onProgressUpdate(Void... values) {}    }}

如果结果数据不是字符串，则可以将

Parcelable

onCreate

getIntent().getExtras.getString('data');
