当我尝试在 imageView 的背景上设置位图时出现致命异常

Question

我明白了

在这一行

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

在 Android 4.4.2 上一切正常，但在较低版本上无法正常工作。我的清单的一部分是

  <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));
}
