android - 如何在 Android 中将 Activity 设置为全屏模式？

Question

如何在 Android 中为 Activity 设置全屏模式？我正在使用以下代码设置全屏，但它会产生错误:

异常(exception):

android.util.AndroidRuntimeException: 
    requestFeature() must be called before adding content.         

代码:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,        
                     WindowManager.LayoutParams.FLAG_FULLSCREEN);
requestWindowFeature(Window.FEATURE_NO_TITLE);

Answer 1

请检查代码

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                            WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.main);
}

并注意它是在设置内容 View 之前设置的
