ImageView:
<ImageView
android:id="@+id/textiv"
android:layout_width="10dp"
android:layout_height="10dp"
android:src="@drawable/textiv"/>
点击事件:
ImageView imageView = (ImageView)findViewById(R.id.textiv)
Drawable drawable = imageView.getDrawable();
BitmapDrawable bitmapDrawable = (BitmapDrawable) drawable;
Bitmap bitmap = bitmapDrawable.getBitmap();
saveImageToGallery(context,drawable);
保存代码:
public static void saveImageToGallery(Context context, Bitmap bitmap) {
// 首先保存图片
File appDir = new File(Environment.getExternalStorageDirectory(), "test");
if (!appDir.exists()) {
appDir.mkdir();
}
String fileName = System.currentTimeMillis() + ".jpg";
File file = new File(appDir, fileName);
try {
FileOutputStream fos = new FileOutputStream(file);
bmp.compress(CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
// 其次把文件插入到系统图库
try {
MediaStore.Images.Media.insertImage(context.getContentResolver(),
file.getAbsolutePath(), fileName, null);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
//最后通知图库更新
Intent intent = new Intent();
intent.setAction(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);//扫描单个文件
intent.setData(Uri.fromFile(file));//给图片的绝对路径
context.sendBroadcast(intent);
Toast.makeText(mContext,"baocun",Toast.LENGTH_SHORT).show();
}
