我的最外层是LinearLayout，自定义CustomLinearLayout继承LinearLayout，重写fitSystemWindows和onApplyWindowInsets两个方法：
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;
}
}
}
替换一下布局文件即可解决问题
