我想在我的应用加载时显示一个初始屏幕，这是我的Java代码：
ImageView splash = (ImageView) this.findViewById(R.id.splashscreen);
splash.postDelayed(new Runnable(){
splash.setVisibility(View.GONE);
}, 3000);
但是我在通话中收到错误“无法解析符号”postDelayed()。此外，我得到了“意外的标记”为
}, 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"/>

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);
}
这activity_splash.xml是您的“splash 活动”布局，YourActivity也是您接下来要进行的“活动”。
