保存在内部存储中捕获的​​图片？

Question

我编码拍照并将其保存在外部存储器中。在我的平板电脑上使用SD卡很好。但是，我的手机有些麻烦，不支持SD卡。任何人都可以帮我写代码来保存在内部存储。谢谢！

    ((Button) findViewById(R.id.btnTaken))
            .setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                            takeImage();                            
                }
                });



protected void takeImage() {
     Log.i(TAG,"onClick event");
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd_HH-mm-ss");
        String currentDateandTime = sdf.format(new Date());
        String fileName = Environment.getExternalStorageDirectory().getAbsolutePath() +
                               "/Image_" + currentDateandTime + ".jpg";


        mCamera.takePicture(fileName);
        Toast.makeText(this, fileName + " saved", Toast.LENGTH_SHORT).show();


}
public void takePicture(final String fileName) {
    Log.i(TAG, "Tacking picture");
    PictureCallback callback = new PictureCallback() {

        private String mPictureFileName = fileName;

        @Override
        public void onPictureTaken(byte[] data, Camera camera) {
            Log.i(TAG, "Saving a bitmap to file");
            Bitmap picture = BitmapFactory.decodeByteArray(data, 0, data.length);
            try {
                FileOutputStream out = new FileOutputStream(mPictureFileName);
                picture.compress(Bitmap.CompressFormat.JPEG, 90, out);
                picture.recycle();
                mCamera.startPreview();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    };

    Camera.ShutterCallback shutter = new Camera.ShutterCallback() {
         public void onShutter() {
         Log.e(getClass().getSimpleName(), "SHUTTER CALLBACK");
         }
         };
         Camera.PictureCallback raw = new Camera.PictureCallback() {
             public void onPictureTaken(byte[] data, Camera c) {
              Log.e(getClass().getSimpleName(), "PICTURE CALLBACK RAW: " + data);
              mCamera.startPreview();
             }
             };
    mCamera.takePicture(shutter, raw, callback) ;



}

Answer 1

这很简单..而不是外部文件路径名。你应该给出内部文件路径名称..这是FileOutputStream out = new FileOutputStream(new File(getFilesDir()+File.separator+"MyFile.jpg")); ..试试吧..它运作良好

和

还有一点，您应该将内部存储的权限添加到Android Manifest.xml文件

中

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