Android输入法遮挡了输入框，使用android:fitsSystemWindows="true"后界面顶部出现白条解决方案

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
