android 闪屏

以下是实现代码：

public class SplashScreenActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        requestWindowFeature(Window.FEATURE_NO_TITLE);        setContentView(R.layout.activity_splash_screen);        // 闪屏的核心代码        new Handler().postDelayed(new Runnable() {            @Override            public void run() {                Intent intent = new Intent(SplashScreenActivity.this, LoginActivity.class); // 从启动动画ui跳转到主ui                startActivity(intent);                SplashScreenActivity.this.finish(); // 结束启动动画界面            }        }, 1000); // 启动动画持续1秒钟    }}
