采用了Android摄像头的意图,得到的URI,然后使用URI [英] Using android camera intent, getting uri, and then using uri
本文介绍了采用了Android摄像头的意图,得到的URI,然后使用URI的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有如下因素code:
I have a folowing code:
public void take_picture(View view)
{
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
ImageView slikaa = (ImageView)this.findViewById(R.id.slikaa);
if ((requestCode == CAMERA_REQUEST)&& (resultCode == Activity.RESULT_OK)) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
slikaa.setImageBitmap(photo);
}
现在我的问题是如何获取图像路径(将其保存到我的数据库),然后再次,用它在图片显示(我不知道怎么弄的路径字符串,然后再利用它)
Now my question is how to get that image path(for saving it to my database), and then again, use it to show in a picture(I don't know how to get String paths, and then re-use it)
推荐答案
有关获取图像路径在onActivityResult则需要通过发送图片的路径,意图以启动相机:
For getting Image Path in onActivityResult you will need to Start camera by send Image Path with Intent as:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
//ContentValues values = new ContentValues();
ContentValues values = new ContentValues(3);
values.put(MediaStore.Images.Media.DISPLAY_NAME, "testing");
values.put(MediaStore.Images.Media.DESCRIPTION, "this is description");
values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
imageFilePath = MainActivity.this.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageFilePath);
startActivityForResult(intent, CAMERA_REQUEST);
和onActivityResult
and on onActivityResult
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
ImageView slikaa = (ImageView)this.findViewById(R.id.slikaa);
if ((requestCode == CAMERA_REQUEST)&& (resultCode == Activity.RESULT_OK)) {
//get image from path
Bitmap photo = (Bitmap) data.getExtras().get("data");
photo = BitmapFactory.decodeStream(this.getContentResolver()
.openInputStream(imageFilePath), null, op);
slikaa.setImageBitmap(pic);
//slikaa.setImageBitmap(photo);
}
