Question

在我的Android应用程序中，我尝试将此xml加载到textview背景中。但它崩溃了

有谁知道什么是错的以及如何解决它？

由于

protected TextView createCountView(Context context, int text, int bg_id) {
    TextView nametv = new TextView(context);
    nametv.setText(String.valueOf(text));
    nametv.setTextAppearance(context, R.style.count);
    nametv.setBackgroundResource(bg_id);
    LinearLayout.LayoutParams textparams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    textparams.gravity = Gravity.CENTER;
    textparams.setMargins(20, 0, 0, 0);
    nametv.setLayoutParams(textparams);
    return nametv;
}

protected TextView createUnAppImageCountView(Context context) {
    return createCountView(context, numberOfUnapprovedImages(), R.drawable.imagecount_bg);
}

imagecount_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<solid xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <solid android:color="#076300"/> 

</solid>

错误

根据链接中的答案，按以下方式更改imagecount_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <solid android:color="#076300"/> 
</shape>

您应将<solid>括在<shape>内，而不是在<solid>

内

将background xml加载到textview时，Android崩溃了
