在 imageclick 上找不到资源异常

Question

我试图在图像点击时增加自定义对话框，但程序显示以下异常。

在图片上点击下面的代码开始行动

iv1.setOnClickListener(new OnClickListener() {
            public void onClick(View arg0) {
                final Dialog d = new Dialog(About.this);
                d.setContentView(R.layout.abtdial);
                d.setTitle("About developer");
                Button dbt = (Button) d.findViewById(R.id.button1);
                dbt.setOnClickListener(new OnClickListener() {
                    public void onClick(View v) {
                        d.dismiss();
                    }
                });
                d.show();
            }
        });

自定义对话框的xml是

   <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/RelativeLayout1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

        <TextView

            android:textColor="#00BFFF"
            android:textSize="50dp" />


        <TextView
            android:id="@+id/textView2"
            android:layout_width="250dp"

            android:layout_alignLeft="@+id/textView1"
            android:layout_below="@+id/textView1"
            android:layout_marginTop="43dp"
            android:text="some text"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:textColor="#848484" />



        <TextView
            android:id="@+id/textView3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_centerHorizontal="true"
            android:text="text abc"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:textColor="#A9E2F3" />


        <Button
            android:id="@+id/button1"
            android:layout_width="match_parent"
            android:layout_height="40dp"
            android:layout_above="@+id/textView3"
            android:layout_centerHorizontal="true"
            android:layout_marginBottom="17dp"
            android:background="@style/btn"
            android:text="Dismiss"
            android:textColor="#00BFFF"
            android:textSize="35dp"
            android:typeface="monospace" />

    </RelativeLayout>

Answer 1

在您的button1 xml 表示中，您有android:background="@style/btn"。 background 属性接受可绘制对象，而不是样式。这就是您收到此异常消息的原因

android.content.res.Resources$NotFoundException: 资源不是 Drawable

参考：android:background

Answer 2

如果您在btn.xml 选择器中有button_pressed、focused 和selected 类似：

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/button_pressed"
          android:state_pressed="true" />
    <item android:drawable="@drawable/button_pressed"
          android:state_focused="true" />
    <item android:drawable="@drawable/button_selected" /> </selector>

你需要把它添加到drawable文件夹中

android:background="@drawable/btn"
