二进制XML文件第0行：膨胀类ImageView时出错

Question

我使用的是Android Studio 3.0，
我已经很累解决此问题。应用程序不执行它总是向我显示此错误二进制XML文件第0行：膨胀类ImageView的错误

这是我的main_activity.xml，我更改了使用ConstraintLayout的xml

  <?xml version="1.0" encoding="utf-8"?>
 <android.support.constraint.ConstraintLayout
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:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.razoo.mywages.MainActivity">

<ImageView
    android:id="@+id/imageView2"
    android:layout_width="wrap_content"
    android:layout_height="517dp"
    android:contentDescription="@string/button3"
    android:scaleType="fitXY"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    android:src="@drawable/doctor" />

<Button
    android:id="@+id/step1btn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="4dp"
    android:background="@color/colorPrimary"
    android:onClick="nextPage"
    android:text="@string/button3"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintVertical_bias="0.498"
    tools:layout_alignParentEnd="true"
    tools:layout_alignParentRight="true"
    tools:layout_alignParentTop="true"
    />

<Button
    android:id="@+id/button3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="16dp"
    android:background="@color/colorPrimary"
    android:text="@string/button3"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    tools:layout_alignParentEnd="true"
    tools:layout_alignParentRight="true"
    tools:layout_alignParentTop="true" />

主要活动的Java代码

public class MainActivity extends Activity {
Button btn1;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_activity);//the error point here
    btn1 = (Button) findViewById(R.id.step1btn);


}
public void nextPage(View view){
    Intent StartNewActivity = new Intent(MainActivity.this, Main2Activity.class);
    startActivity(StartNewActivity);

  }
 }

这是完整的日志，

Answer 1

似乎不完全支持某些SVG源。在活动的onCreate（）方法中添加以下行：

AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);

并确保您在XML文件中使用以下属性作为ImageView的属性：app：srcCompact而不是android：src来定义图像。
