android 透明状态栏，根布局设置fitSystemWindows = “true”后状态栏变成白色

这篇文章作者是使用了自定义LinearLayout解决的

public class CustomLinearLayout extends LinearLayout {
    public CustomLinearLayout(Context context) {
        super(context);
    }

    public CustomLinearLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomLinearLayout(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    public CustomLinearLayout(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    @Override
    protected boolean fitSystemWindows(Rect insets) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            insets.left = 0;
            insets.top = 0;
            insets.right = 0;
        }
        return super.fitSystemWindows(insets);
    }

    @RequiresApi(api = Build.VERSION_CODES.KITKAT_WATCH)
    @Override
    public WindowInsets onApplyWindowInsets(WindowInsets insets) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            return super.onApplyWindowInsets(insets.replaceSystemWindowInsets(0, 0, 0, insets.getSystemWindowInsetBottom()));
        } else {
            return insets;
        }
    }
}

 

 

也可以不在根布局加 fitSystemWindows = “true”，而写在内部，在顶部写一个LinearLayout添加fitSystemWindows = “true”属性
