Question

我有两个活动，其中第一个有一个按钮，点击时应该转到下一个活动。但是当点击时我得到以下错误。我有一个ImageView，其背景是三角形的。当我删除imageview它工作正常。

以下是错误：

PickDrop的Java代码：公共类PickDrop扩展了AppCompatActivity {

  @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.pick_drop);

    }
}

triangle_shape（编辑）.XML：

<?xml version="1.0" encoding="utf-8"?>

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <rotate
            android:fromDegrees="-45"
            android:toDegrees="45"
            android:pivotX="220%"
            android:pivotY="70%" >
            <shape
                android:shape="rectangle" >
                <stroke android:color="#fff" android:width="1dp"/>
                <solid

            </shape>
        </rotate>
    </item>
</layer-list>

Answer 1

请检查你的xml文件是否在drawable文件夹中？

资源$ NotFoundException：来自drawable的文件res / drawable / triange_shape.xml

Answer 2

尝试使用Shape标签创建三角形。
