我正在制作一个图库应用并使用下面的代码动态添加图像按钮,这适用于我的一个设备,但另一个我得到了
java.lang.RuntimeException: Unable to start activity ComponentInfo{package/package.MainActivity}: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

错误,但在其他设备上没有任何问题,它运行正常。它正在运行的那个是运行4.1.2而它崩溃的那个运行4.1.1可能就是这样吗?项目的最小和目标sdk是16
setContentView(R.layout.activity_main);
// Hook up clicks on the thumbnail views.
imgHolder = (LinearLayout)findViewById(R.id.imgHolder);
for(int x = 0; x < files.length; x++)
{
Log.d("Conor",files[x].getAbsolutePath());
Drawable img = Drawable.createFromPath(files[x].getAbsolutePath());
imgs.add(img);
thumbs.add(new ImageButtons(this, files[x].getAbsolutePath(),x));
thumbs.get(x).setImageDrawable(img);
thumbs.get(x).setOnClickListener(onCl);
imgHolder.addView(thumbs.get(x));
}
// Retrieve and cache the system's default "short" animation time.
mShortAnimationDuration = getResources().getInteger(android.R.integer.config_shortAnimTime);
ImageButtons类thumbs
是
import java.io.IOException;
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;

import android.content.res.Resources;

import android.view.ViewGroup.LayoutParams;
import android.widget.ImageButton;
public class ImageButtons extends ImageButton{
Resources res = getResources();
public ImageButtons(Context context,String img,int id)
{
super(context);
XmlPullParser parser = res.getXml(R.layout.imagebuttons);
AttributeSet attributes = null;
int state = 0;
while(state != XmlPullParser.END_DOCUMENT)
{
try {
state = parser.next();
} catch (XmlPullParserException e1) {
e1.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
}
if (state == XmlPullParser.START_TAG) {
if (parser.getName().equals("ImageButton")) {
attributes = Xml.asAttributeSet(parser);
break;
}
}
}
setId(id);
setLayoutParams(new LayoutParams(context, attributes));
}
}
拇指是ArrayList<ImageButton>
第74行是指`imgHolder.addView(thumbs.get(x));
我的问题再一次是为什么这适用于某些设备但不适用于其他设备
答案 0 :(得分:3)
您可能需要额外处理:
View v = thumbs.get(x);
ViewGroup p = (ViewGroup)v.getParent();
p.removeView(v);
imgHolder.addView(v);
