Question

我得到了

    java.lang.NoSuchMethodError: android.widget.ImageView.setBackground

    at dalvik.system.NativeStart.main(Native Method)

在这一行

imageView.setBackground(new BitmapDrawable(getResources(),k));

所有在Android 4.4.2上工作正常，但它不适用于较低版本。我的部分内容是

  <uses-sdk android:minSdkVersion="10"
        android:targetSdkVersion="17"/>

Answer 1

请试试这个：

int sdk = android.os.Build.VERSION.SDK_INT;
if(sdk < android.os.Build.VERSION_CODES.JELLY_BEAN) {
    //if you want take image from resources - getResources().getDrawable(your_id)
    imageView.setBackgroundDrawable(new BitmapDrawable(getResources(),k)));

} else {
    imageView.setBackground(new BitmapDrawable(getResources(),k));
}

当我尝试在imageView的背景上设置位图时出现致命异常
