我一直在使用customViewClass,效果很好,直到将compileSdkVersion
和targetSdkVersion
从19升级到22为止。
在compileSdkVersion 19
上仍然可以正常工作。
在stacktrace中,您还可能会看到它也抛出ClassNotFoundException
,因为它不存在DexPathList
这是我的build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "uk.org.example.hfi"
minSdkVersion 16
targetSdkVersion 22
multiDexEnabled true
}
dexOptions {
jumboMode = true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile project(':dragSortListview')
compile 'com.github.bumptech.glide:glide:3.5.2'
compile 'com.android.support:support-v4:22.1.0'
compile 'com.google.code.gson:gson:2.2.4'
compile files('libs/android-query-full.0.26.7.jar')
compile files('libs/aws-android-sdk-2.1.5-cognito.jar')
compile files('libs/aws-android-sdk-2.1.5-core.jar')
compile files('libs/aws-android-sdk-2.1.5-s3.jar')
compile files('libs/isoviewer-2.0-RC-22.jar')
compile files('libs/javacpp.jar')
compile files('libs/javacv.jar')
compile files('libs/libGoogleAnalyticsServices.jar')
}
这是我自定义的ViewClass
package uk.org.example.hfi.CustomClasses;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.ImageView;
public class RatioImageView extends ImageView {
public RatioImageView(Context context) {
super(context);
}
public RatioImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public RatioImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int h = MeasureSpec.getSize(heightMeasureSpec);
int w = h*3/4;
setMeasuredDimension(w, h);
}
}
这就是我的使用方式
<uk.org.example.hfi.CustomClasses.RatioImageView
android:id="@+id/iv_ProfileImage"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:src="@drawable/profile_pic"
android:scaleType="centerInside"/>
这是完整的堆栈跟踪:Dex还会引发未找到类的异常

请不要将其标记为重复,因为我已经尝试了所有其他答案,没有其他为我工作!
最佳答案
由于您将compileSdkVersion和targetSdkVersion从19升级到22,因此您的buildToolsVersion应该相应地升级,例如:
compileSdkVersion 22
buildToolsVersion "22.0.0"
如果您的buildToolsVersion> = 22,则将buildToolsVersion更改为它,否则,应使用sdkmanager下载它。
