InflateException：二进制XML文件行＃23：错误导致类

Question

我想创建自定义视图，需要根据不同的情况更改背景资源。

我的CustomViewClass：

public class MessageCloudView extends LinearLayout{

private enum State {
    STABLE, CHECKED, HOVERED, RESEND, ERROR;
}

/**
 * 0 - stable view background
 * 1 - checked_background
 * 2 - hovered_background
 * 3 - resend_background
 */

private State currentState, prevState;
private int[] res;

public MessageCloudView(Context context) {
    super(context);
    init(context, null);
}

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

private void init(Context context, AttributeSet attrs) {
    this.currentState = State.STABLE;
    this.res = new int[4];

    TypedArray a = context.getTheme().obtainStyledAttributes(attrs, R.styleable.MessageCloudView, 0, 0);
    try {
        res[0] = a.getInteger(R.styleable.MessageCloudView_stable_background, 0);
        res[1] = a.getInteger(R.styleable.MessageCloudView_checked_background, 0);
        res[2] = a.getInteger(R.styleable.MessageCloudView_hovered_background, 0);
        res[3] = a.getInteger(R.styleable.MessageCloudView_resend_background, 0);
    } finally {
        a.recycle();
    }
    setBackgroundResource(res[0]);
}

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

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

@Override
public void setPressed(boolean pressed) {
    this.prevState = this.currentState;
    if(pressed){
        this.currentState = State.HOVERED;
    } else {
        this.currentState = this.prevState;
    }
    super.setPressed(pressed);
    onDrawableCheck();
}


@Override
public void setSelected(boolean selected) {
    this.prevState = this.currentState;
    if(selected){
        this.currentState = State.HOVERED;
    } else {
        this.currentState = this.prevState;
    }
    super.setSelected(selected);
    onDrawableCheck();
}

private void onDrawableCheck(){
    if(this.currentState == State.STABLE) setBackgroundResource(res[0]);
    else if(this.currentState == State.CHECKED)  setBackgroundResource(res[0]);
    else if(this.currentState == State.HOVERED) setBackgroundResource(res[0]);
    else if(this.currentState == State.RESEND) setBackgroundResource(res[0]);
    else if(this.currentState == State.ERROR) setBackgroundResource(res[0]);
}

public void setResent(boolean isResent){
    if(isResent) this.currentState = State.RESEND;
    else this.currentState = State.STABLE;
    onDrawableCheck();
}

public void setError(boolean isError){

}

}

attrs 文件包含：

<declare-styleable name="MessageCloudView">
    <attr name="stable_background" format="integer" />
    <attr name="checked_background" format="integer" />
    <attr name="hovered_background" format="integer" />
    <attr name="resend_background" format="integer" />
</declare-styleable>

xml文件中的

：

 <custom.MessageCloudView
        android:id="@+id/ll_message_background"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_marginBottom="2dp"
        android:layout_marginTop="5dp"
        android:minWidth="65dp"
        android:orientation="vertical"
        android:paddingBottom="2dp"
        android:paddingLeft="2dp"
        android:paddingRight="9dp"
        prop:stable_background="@drawable/cloud_messages_contact_document_1080"
        prop:checked_background="@drawable/cloud_messages_contact_document_1080_selected_06"
        prop:hovered_background="@drawable/cloud_messages_contact_document_1080_selected_06"
        prop:resend_background="@drawable/cloud_messages_user_document_1080_red"
        android:paddingTop="0dp">

但是当我试图通过以下方式在适配器中扩展我的视图时： inflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE); inflater.inflate(R.layout.chat_messages_item_me, parent, false);

错误

我收到错误，我认为这是因为我在自定义视图中出错：
