Android：闪屏问题

我使用以下代码创建了一个启动屏幕：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.setContentView(R.layout.splash_layout);

    Thread splashThread = new Thread() {
        @Override
        public void run() {
            try {
                int waited = 0;
                while (_active && (waited < _splashTime)) {
                    sleep(100);
                    if (_active) {
                        waited += 100;
                    }
                }
            } catch (InterruptedException e) {
                // do nothing
            } finally {
                _active = false;
                finish();
                startActivity(new Intent(SplashActivity.this, MyMainActivity.class));
            }
        }
    };

    splashThread.start();
}

public void onCreate（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
这个.setContentView（R.layout.splash_布局）；
线程飞溅线程=新线程（）{
@凌驾
公开募捐{
试一试{
int=0；
while（_active&&（waiting<_splashTime））{
睡眠（100）；
如果（_活动）{
平均值+=100；
}
}
}捕捉（中断异常e）{
//无所事事
}最后{
_主动=假；
完成（）；
startActivity（新意图（SplashActivity.this、MyMainActivity.class））；
}
}
};
splashtread.start（）；
}

在splash_布局中有一个图像视图，在splash屏幕出现一段时间后消失，然后MyMainActivity开始，问题是，在splash消失后，在MyMainActivity开始之前，我可以看到上一个屏幕（与我的应用程序无关，例如带有小部件的桌面或以前运行的应用程序），如何使转换流畅，以便启动屏幕直接进入MyMainActivity

谢谢

你能试试吗我不确定这是100%的工作，但试试可能会有帮助

protected int _splashTime = 3000;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash_layout);
    Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        public void run() {
            finish();
            startActivity(new Intent(SplashActivity.this, MyMainActivity.class));
        }
    }, _splashTime);
}

这里是一个最好的例子供您参考。

这里是一个最好的例子。

尝试在

startActivity（）之后调用
finish（）
尝试在
startActivity（）之后调用
finish（）
您可以尝试以下代码：1

public class MainActivity extends Activity {
    private ImageView splashImageView;
    boolean splashloading = false;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        splashImageView = new ImageView(this);
        splashImageView.setScaleType(ScaleType.FIT_XY);
        splashImageView.setImageResource(R.drawable.ic_launcher);
        setContentView(splashImageView);
        // interesting music
        /**
         * Gets your sound file from res/raw
         */
        splashloading = true;
        Handler h = new Handler();
        h.postDelayed(new Runnable() {
            public void run() {
                splashloading = false;
                setContentView(R.layout.activity_main);
            }

        }, 3000);

    }

祝你好运

 谢谢我试过了，结果是一样的，当飞溅在活动开始前消失时，我仍然可以看到桌面或以前的应用程序。我修改了布局文件，现在它工作了，我给图像的父线性布局添加了黑色背景色。谢谢我试过了，结果是一样的，在活动开始之前，当飞溅消失时，我仍然可以看到桌面或以前的应用程序。我修改了布局文件，现在它可以工作了，我在图像的父线性布局中添加了黑色背景色。
