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

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);
          }
