如何从一个活动图像发送到从Android图库中选择另一个活动?
问题描述:
我想设置的图像是从Android图库选择。
我用这个code获得所选图像。
I want to set the Image to be Selected from the Android Gallery. I use this code to get selected Image.
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);//
//startActivity(intent);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),10);
和该方法的onActivityResult就像是:
And the onActivityResult Method is like:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 10 && resultCode == Activity.RESULT_OK) {
Uri contentUri = data.getData();
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String tmppath = cursor.getString(column_index);
Bitmap croppedImage = BitmapFactory.decodeFile(tmppath);
go.setVisibility(View.VISIBLE);
//canvas.drawBitmap(kangoo, 130, 100, null);
//previewImage.setVisibility(View.VISIBLE);
imageSrc.setImageBitmap(croppedImage); //set to your imageview
}
}
现在,我想从库中选择图像并将其发送到另一个活动。那么它是如何可能的上述code?
谢谢你。

您可以通过图像到下一个活动的
。 URI
You can pass the URI
of the Image to next Activity
.
在 URI
你从获得的onActivityResult()
和的onCreate()
接下来活动的

德code中的位图
再次将其设置为的ImageView
Decode the Bitmap
again and set it to ImageView
