如何将Android相机中的图像保存到特定文件夹？

Question

基本上，我想要做的是允许用户创建自己的文件夹，然后转到包含按钮的activity来启动相机。

从那里我希望能够启动相机并将相机图像保存到新创建的文件夹中。

我在将相机图像保存到新创建的文件夹的最后部分时遇到问题。

这是我的代码：

 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Button b = (Button) findViewById(R.id.button1);
    b.setOnClickListener(new OnClickListener() {


        EditText text = (EditText)findViewById(R.id.editText1); 
        EditText text2 = (EditText)findViewById(R.id.editText2);



        @Override
        public void onClick(View v) {

            final String name = text.getText().toString();
            final String placeName = text2.getText().toString(); 

            String place = placeName.substring(0,3);
            String direct = name + place ;

            File folder = new File("/sdcard/CameraTest/" + direct + "/");
            folder.mkdirs();

            Intent myIntent = new Intent(CameraTestActivity.this, Press.class);
            myIntent.putExtra("key", "/sdcard/CameraTest/" + direct + "/");
            startActivity(myIntent);

        }
    });

从这里我过渡到此活动：

public class Press extends Activity {


    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.afterenter);
        final String direct = this.getIntent().getStringExtra("key");


        // TODO Auto-generated method stub
        Button p = (Button) findViewById(R.id.button2);
        p.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                Intent camera= new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

                startActivityForResult(camera, 1);

            }
        });



    Button np = (Button) findViewById(R.id.button3);
    np.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent next = new Intent(Press.this, CameraTestActivity.class);
            startActivity(next);
        }
    });         
    }
}

请告诉我如何将相机中的图像保存到新创建的文件夹中。

我希望用户能够拍摄多张照片，然后将这些照片保存到该特定文件夹中。

在调用相机活动之前添加此代码，

Uri uriSavedImage=Uri.fromFile(new File("/sdcard/flashCropped.png"));
camera.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(camera, 1);

试试这个......

path = Environment.getExternalStorageDirectory() + "/photo1.jpg";
File file = new File(path);
Uri outputFileUri = Uri.fromFile(file);
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY);

并且您还没有实现 onActivityResult() 尝试一下这可能会对您有所帮助。

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    System.gc();
    if (requestCode == CAPTURE_IMAGE_ACTIVITY) {
        if (resultCode == Activity.RESULT_OK) {
            try {
                // Call function MakeFolder to create folder structure if
                // its not created
                if(imageBitmap != null) {
                    imageBitmap = null;
                    imageBitmap.recycle();
                }
                MakeFolder();
                // Get file from temp1 file where image has been stored
                BitmapFactory.Options options = new BitmapFactory.Options();
                options.inSampleSize = 3;
                imageBitmap = BitmapFactory.decodeFile(path, options);
                imgForPhotograph.setImageBitmap(imageBitmap);
                isImageTaken = true;
                // Name for image
                IMAGEPATH = getString(R.string.chassisImage)
                        + System.currentTimeMillis();
                SaveImageFile(imageBitmap,IMAGEPATH);
            } catch (Exception e) {
                Toast.makeText(this, "Picture Not taken",
                                Toast.LENGTH_LONG).show();
                e.printStackTrace();
            }
        }
    }

您应该将文件位置添加到图像捕获意图中。
例如：

camera.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, [file location]);
