私はアンドロイドアプリケーションで作業しているので、写真を撮って保存する必要があります。それは働いて、私の画像は電話のディレクトリに保存されます。特に、Pictureディレクトリにあります。Androidアプリケーション：ディスプレイ画像
だから、ここカメラ（新しいアクティビティ）を起動し、写真を撮るためにボタンとの私のクラスのパラメータ：
public class Parametre extends Activity {
private EditText ETpseudo= null;
private Button buttonPhoto = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.parametres);
ETpseudo =(EditText) findViewById(R.id.editPseudo);
buttonPhoto = (Button) findViewById(R.id.buttonPhoto);
//ivPhoto.setImageBitmap();
buttonPhoto.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity(new Intent(Parametre.this, CameraActivity.class));
}
});
}
}
CameraActivity：だから
public class CameraActivity extends Activity {
private Camera mCamera;
private CameraPreview mCameraPreview;
private ImageView cadrePhoto = null;
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
Log.d("DEBUG", String.valueOf(grantResults[0]));
startCamera();
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.camera);
Button captureButton = (Button) findViewById(R.id.button_capture);
startCamera();
captureButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mCamera.takePicture(null, null, mPicture);
}
});
}
private void startCamera(){
mCamera = getCameraInstance();
mCamera.startPreview();
mCameraPreview = new CameraPreview(this, mCamera);
FrameLayout preview = (FrameLayout) findViewById(R.id.camera_preview);
preview.addView(mCameraPreview);
setCameraDisplayOrientation(this, 1, mCamera);
}
/**
* Helper method to access the camera returns null if it cannot get the
* camera or does not exist
*
* @return
*/
@TargetApi(Build.VERSION_CODES.GINGERBREAD)
private Camera getCameraInstance() {
Camera camera = null;
try {
camera = Camera.open(1);
} catch (Exception e) {
e.printStackTrace();
}
return camera;
}
@TargetApi(Build.VERSION_CODES.GINGERBREAD)
public void setCameraDisplayOrientation(Activity activity, int cameraId,android.hardware.Camera camera) {
android.hardware.Camera.CameraInfo info = new android.hardware.Camera.CameraInfo();
android.hardware.Camera.getCameraInfo(cameraId, info);
int rotation = activity.getWindowManager().getDefaultDisplay().getRotation();
int degrees = 0;
switch (rotation) {
case Surface.ROTATION_0:
degrees = 0;
break;
case Surface.ROTATION_90:
degrees = 90;
break;
case Surface.ROTATION_180:
degrees = 180;
break;
case Surface.ROTATION_270:
degrees = 270;
break;
}
int result;
if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
result = (info.orientation + degrees) % 360;
result = (360 - result) % 360; // compensate the mirror
} else { // back-facing
result = (info.orientation - degrees + 360) % 360;
}
camera.setDisplayOrientation(result);
}
Camera.PictureCallback mPicture = new Camera.PictureCallback() {
@Override
public void onPictureTaken(byte[] data, Camera camera) {
File pictureFile = getOutputMediaFile();
if (pictureFile == null) {
Log.d("Error", "Error creating media file, check storage permissions: ");
return;
}
try {
FileOutputStream fos = new FileOutputStream(pictureFile);
fos.write(data);
fos.close();
} catch (FileNotFoundException e) {
Log.d("DBG", "File not found: " + e.getMessage());
} catch (IOException e) {
Log.d("Error", "Error accessing file: " + e.getMessage());
}
}
};
private static File getOutputMediaFile() {
File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "MyCameraApp");
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
Log.d("MyCameraApp", "failed to create directory");
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
File mediaFile;
mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_" + timeStamp + ".jpg");
return mediaFile;
}
}
、服用後写真、私はImageView上の画像をパラメータビューで表示したいと思います。しかし、私はこれを行う方法を知らない。どのように写真を取得し、パラメータの表示で彼を表示するには？
ありがとうございました。
私の英語のため申し訳ありません：/
