推荐答案

尝试以下code，

public class Splash extends Activity {

    private static final int SPLASH_SHOW_TIME = 1000;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
//      
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_splash);

        new BackgroundSplashTask().execute();

    }

    private class BackgroundSplashTask extends AsyncTask<Void, Void, Void> {

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
        }

        @Override
        protected Void doInBackground(Void... arg0) {
            try {
                Thread.sleep(SPLASH_SHOW_TIME);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

            return null;
        }

        @Override
        protected void onPostExecute(Void result) {
            super.onPostExecute(result);
            Intent i = new Intent(Splash.this, LockPatern.class);
            startActivity(i);
            finish();
        }

    }
}

这就是它
