私のアプリは電話のカメラを使用して写真を撮り、その写真を電話ギャラリーに保存します。次に、その画像パスを取得して、データストアに保存したいと思います。誰か助けてくれませんか？これが私のコードです：

public void onClick(View v){
        switch(v.getId())
        {
            case R.id.btnLoadPic:

                //Options for the dialogue menu
                final CharSequence[] items = {"Camera", "Gallery"};

                AlertDialog.Builder builder = new AlertDialog.Builder(this);
                builder.setTitle("Choose an Option");
                builder.setItems(items, new DialogInterface.OnClickListener() {
                    /**
                     * Make onclick functionality for the options in the dialogue menu
                     */
                    public void onClick(DialogInterface dialog, int item) {

                        // Camera option
                        if (item == 0){

                            PackageManager pm = getPackageManager();

                            if (pm.hasSystemFeature(PackageManager.FEATURE_CAMERA)){
                                //Toast.makeText(this, "camera", Toast.LENGTH_SHORT).show();
                                dispatchTakePictureIntent(11);
                            } else {
                                Toast.makeText(null, "No camera avalible", Toast.LENGTH_SHORT).show();

                            }
                        }
                        // Gallery option this works fine


    private void dispatchTakePictureIntent(int actionCode) {
            Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(takePictureIntent, actionCode);


            //handleSmallCameraPhoto(takePictureIntent);
        }

        private void handleSmallCameraPhoto(Intent intent) {
            Bundle extras = intent.getExtras();
            Bitmap mImageBitmap = (Bitmap) extras.get("data");
            ImageView mImageView = (ImageView) this.findViewById(R.id.imagePlayer);
            mImageView.setImageBitmap(mImageBitmap);

        }

        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            handleSmallCameraPhoto(data);
        }

コードの最後のビットはカメラにアクセスし、画像を画像ビューに表示します。その画像パスを文字列形式で取得するにはどうすればよいですか？

これは役に立ちます。テストして動作しました！

public class MainActivity extends Activity {

    private static final int REQUEST_IMAGE = 100;   
    private static final String TAG = "MainActivity";

    TextView tvPath;
    ImageView picture;
    File destination;
        String imagePath;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        tvPath = (TextView) findViewById(R.id.idTvPath);
        picture = (ImageView) findViewById(R.id.idIvImage);
        String name =   dateToString(new Date(),"yyyy-MM-dd-hh-mm-ss");
        destination = new File(Environment.getExternalStorageDirectory(), name + ".jpg");

        Button click = (Button) findViewById(R.id.idBtnTakePicture);
        click.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(destination));
                startActivityForResult(intent, REQUEST_IMAGE);

            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if( requestCode == REQUEST_IMAGE && resultCode == Activity.RESULT_OK ){
            try {
                FileInputStream in = new FileInputStream(destination);
                BitmapFactory.Options options = new BitmapFactory.Options();
                options.inSampleSize = 10;
                imagePath = destination.getAbsolutePath();
                tvPath.setText(imagePath);
                Bitmap bmp = BitmapFactory.decodeStream(in, null, options);
                picture.setImageBitmap(bmp);
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }

        }
        else{
            tvPath.setText("Request cancelled");
        }
    }

    public String dateToString(Date date, String format) {
        SimpleDateFormat df = new SimpleDateFormat(format);
        return df.format(date);
    }

}

マニフェストファイルにこれらを追加することを忘れないでください：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.CAMERA"/>
