How do I show a splash screen in Android?(如何在Android中显示闪屏？)

本文介绍了如何在Android中显示闪屏？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我想在应用程序加载时显示闪屏，这是我的Java代码：

ImageView splash = (ImageView) this.findViewById(R.id.splashscreen);

splash.postDelayed(new Runnable(){
    splash.setVisibility(View.GONE);
}, 3000);

但我在postDelayed()调用中收到错误"无法解析符号"。我还收到了"意外令牌"

}, 3000);

最后，这是我的布局：

<TextView
    android:text="@string/hello_world"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

<ImageView
    android:id="@+id/splashscreen"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:src="@drawable/splash"
    android:layout_gravity="center"/>

推荐答案

您可以执行以下操作：

private static final int SPLASH_TIME_OUT = 2000;
private static final Handler mHandler = new Handler();

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

    mHandler.postDelayed(new Runnable() {

        @Override
        public void run() {

                startActivity(new Intent(getApplicationContext(), YourActivity.class)); 
                finish();   
        }
    }, SPLASH_TIME_OUT);    
}
