我正在制作一个应用程序,发送从相机应用程序拍摄的照片,但它返回的图像似乎只是一个缩略图,我怎么能得到它来打开整个图像?在Android中使用相机应用程序时,如何返回整个图像而不仅仅是缩略图?
以下代码获取图像,但它太小。
public class OnTheJobActivity extends Activity{
private static final int CAMERA_PIC_REQUEST = 1337;
private Button takePictureButton;
private Button sendPictureButton;
private Bitmap thumbnail;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setRequestedOrientation(
ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
setContentView(R.layout.onthejob);
takePictureButton = (Button) findViewById(R.id.takePictureButton);
takePictureButton.setOnClickListener(takePictureButtonListener);
sendPictureButton = (Button) findViewById(R.id.sendPictureButton);
sendPictureButton.setOnClickListener(sendPictureButtonListener);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
thumbnail = (Bitmap) data.getExtras().get("data");
ImageView image = (ImageView) findViewById(R.id.photoResultView);
image.setImageBitmap(thumbnail);
sendPictureButton.setVisibility(Button.VISIBLE);
}
}
private OnClickListener takePictureButtonListener = new OnClickListener() {
@Override
public void onClick(View arg0){
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
};
private OnClickListener sendPictureButtonListener = new OnClickListener() {
@Override
public void onClick(View arg0){
Intent i = new Intent(Intent.ACTION_SEND);
i.putExtra(Intent.EXTRA_EMAIL, "[email protected]");
i.putExtra(Intent.EXTRA_SUBJECT,"On The Job");
i.putExtra(Intent.EXTRA_STREAM, thumbnail);
i.setType("image/bmp");
startActivity(Intent.createChooser(i,"Emailfile"));
}
};
}
愚蠢的问题,什么分辨率的图像是相机设置取? – Basic 2011-01-31 19:36:54
