Question

我正在尝试在服务中使用WindowManager添加自定义的KnockView。这是KnockView类。

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

    public KnowView(Context context, AttributeSet attrs) {
        super(context, attrs);

        TypedArray typedArray = context.obtainStyledAttributes(attrs, R.styleable.KnowView);
        try {
            isFromChangeKnock = typedArray.getBoolean(R.styleable.KnowView_changeKnock, false);
        } catch (Exception e) {
            e.printStackTrace();

        } finally {
            typedArray.recycle();
        }
        initView();
    }

    public KnowView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        initView();
    }
     private void initView() {
        mainLayout = inflate(getContext(), R.layout.knock_code, this);
    }

}

因此，基本上，在KnowView类中，我们将另一种布局（knock_code）夸大并将其添加到KnowView中。之后，我在另一个布局中使用此自定义Knockview。 main_view.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/parent_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorPrimary"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <production.kado.lock.views.KnowView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:paddingBottom="20dp"
        app:changeKnock="true" />
    </RelativeLayout>

并在这样的WindowManager中使main_view.xml投入使用。

WindowManager windowManager = ((WindowManager) 
this.getSystemService(WINDOW_SERVICE));

View view1 = LayoutInflater.from(this).inflate(R.layout.main_view, null);
windowManager.addView(mainView, getViewParam(true));

但是运行此服务时，我遇到了这些异常。

我还在活动中使用了KnockView，但是在活动中，它工作正常。唯一的问题是与WindowManager一起用于服务中。

Answer 1

我发现了我正在使用的问题

android:background="?selectableItemBackground"

删除此按钮后，

我的布局按钮中的属性正常工作

在服务中使用WindowManager时，自定义视图不会膨胀
