Android调用系统相册选择图片,支持小米4云相册

Intent intent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, yourRequestCode);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
//获取图片路径
if (requestCode == yourRequestCode && resultCode == Activity.RESULT_OK && data != null) {
Uri localUri = data.getData();
String scheme = localUri.getScheme();
String imagePath = "";
if("content".equals(scheme)){
String[] filePathColumns = {MediaStore.Images.Media.DATA};
Cursor c = getContentResolver().query(localUri, filePathColumns, null, null, null);
c.moveToFirst();
int columnIndex = c.getColumnIndex(filePathColumns[0]);
imagePath = c.getString(columnIndex);
}else if("file".equals(scheme)){//小米4选择云相册中的图片是根据此方法获得路径
imagePath = localUri.getPath();
}
showImage(imagePath);//拿到图片路径后处理
c.close();
}
}
