如何仅选择相机从画廊捕获图像

Question

我只想从相机上单击的画廊中选择那些图像，而不是从其他来源出现。

Cursor imagecursor = getApplicationContext().getContentResolver().query(
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                new String[] {MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID}, null,
                null, null);

此查询给了我所有图像。

我想要相机图像的路径，无论画廊和相机的意图如何

这是一个示例，希望它有帮助！

package com.mahesh.gallerytestapp;

public class MainActivity extends Activity {
Uri selectedImageUri;
String  selectedPath;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button b = (Button) findViewById(R.id.bGallery);
Button bCam= (Button) findViewById(R.id.bCamera);
ImageView preview = findViewById(R.id.preview);
bCam.setOnClickListener(new OnClickListener() {
 @Override
 public void onClick(View v) {
  // TODO Auto-generated method stub
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
            startActivityForResult(cameraIntent, 100); 
 }
});

b.setOnClickListener(new OnClickListener() {
 @Override
 public void onClick(View v) {
  // TODO Auto-generated method stub
 openGallery(10);
 }
});
}

 public void openGallery(int req_code){
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent,"Select file to upload "), req_code);
 }
public void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (resultCode == RESULT_OK) {
     if(data.getData() != null){
       selectedImageUri = data.getData();
     }else{
      Log.d("selectedPath1 : ","Came here its null !");
      Toast.makeText(getApplicationContext(), "failed to get Image!", 500).show();
     }
     if (requestCode == 100 && resultCode == RESULT_OK) {  
            Bitmap photo = (Bitmap) data.getExtras().get("data"); 
            selectedPath = getPath(selectedImageUri);
            preview.setImageURI(selectedImageUri);
            Log.d("selectedPath1 : " ,selectedPath);
        } 
        if (requestCode == 10)
        {
           selectedPath = getPath(selectedImageUri);
           preview.setImageURI(selectedImageUri);
           Log.d("selectedPath1 : " ,selectedPath);
        }
    }
}

public String getPath(Uri uri) {
    String[] projection = { MediaStore.Images.Media.DATA };
    Cursor cursor = managedQuery(uri, projection, null, null, null);
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}
 }
