如何在内部存储中保存图像并在imageView中以另一个活动显示图像

Question

如何在内部存储中保存图像并在imageView中以另一个活动显示图像，请告诉我如何将该图像保存在内部存储中，因为许多手机只有内部存储而不是SD卡

这是我的第一个活动

 //camera
    camera = (ImageView) findViewById(R.id.takePic);
    camera.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            File pictureDirectory=Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
            String pictureName=getPictureName();
            File imageFile=new File(pictureDirectory,pictureName);
             pictureUri=Uri.fromFile(imageFile);
            intent.putExtra(MediaStore.EXTRA_OUTPUT,pictureUri);
            startActivityForResult(intent,CAMERA_REQUEST_CODE);

        }
    });

 private String getPictureName() {

    SimpleDateFormat sdf=new SimpleDateFormat("yyyyMMdd_HHmmss");
    String timestamp=sdf.format(new Date());
    return "Plane place image"+timestamp+".jpg";

}

  @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode==RESULT_OK){
        if (resultCode==CAMERA_REQUEST_CODE)
        {
            pictureUri = data.getData();
            if (pictureUri!=null) {
                Intent intent = new Intent(this, PictureActivity.class);
                intent.setData(pictureUri);
                intent.putExtra("imgUrl", pictureUri.toString());
                startActivity(intent);
            }
        }
    }
}

这是我的第二项活动

 Bundle bundle = getIntent().getExtras();

    if (bundle != null) {
        Log.e("ashish", bundle.getString("imgUrl") + "");
         path = Uri.parse(bundle.getString("imgUrl"));

    }

    ImageView selfiiii = (ImageView) findViewById(R.id.mySelfie);
    selfiiii.setImageURI(path);

Answer 1

我将图像存储在代码下面的模拟器内部存储中...

created_at

Answer 2

在opencamera方法中进行更改，例如在代码下面使用...

    private void OpenCamera(){
    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(cameraIntent, CAMERA_REQUEST_CODE);
}
 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Bitmap thumbnail = null;

    if (resultCode==RESULT_OK){
        if (requestCode==CAMERA_REQUEST_CODE)
        {
                thumbnail = (Bitmap) data.getExtras().get("data");
                Intent intent = new Intent(this, DbInsert.class);
                intent.putExtra("name", thumbnail);
                startActivity(intent);
            }

    }
}

第二项活动......

        Bitmap bitmap  = getIntent().getExtras().getParcelable("name");
    imageView.setImageBitmap(bitmap);
