java - 我想在不将图片保存到图库的情况下打开 android 相机

Question

如果可能的话，我希望图片直接转到 ImageView，而不将其保存到图库。如屏幕截图所示，它每次都会要求保存并直接保存到图库中。这可以实现吗，还是我必须制作自己的 ImageView 相机？

public class Main extends Activity {

ImageView ivPhoto;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    ivPhoto = (ImageView) findViewById(R.id.ivPic);
}

public void TakePhoto(View v){
    Intent camIntent = new      Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(camIntent,0);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode==0){
        Bitmap camImage = (Bitmap) data.getExtras().get("data");
        ivPhoto.setImageBitmap(camImage);
    }
}

终于得到了我想要的。谢谢大家

public class Main extends Activity {

ImageView ivPhoto;
File myFilesDir;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    ivPhoto = (ImageView) findViewById(R.id.ivPic);
    myFilesDir = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Android/data/com.example.project/files");
    System.out.println (myFilesDir);
    myFilesDir.mkdirs();
}

public void TakePhoto(View v){
    Intent camIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    camIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(myFilesDir.toString()+"/temp.jpg")));
    startActivityForResult(camIntent, 0);
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode==0){
        try {
            Bitmap cameraBitmap;
            cameraBitmap = BitmapFactory.decodeFile(myFilesDir + "/temp.jpg");
            Bitmap.createBitmap(cameraBitmap);
            ivPhoto.setImageBitmap(cameraBitmap);
        }
        catch(Exception e){
            e.printStackTrace();
        }
    }
}
