我有两项活动(A1,A2).A1调用A2,从A2调用相机意图,如下所示

launchIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
launchIntent.putExtra(MediaStore.EXTRA_OUTPUT,photoPath);   
startActivityForResult(launchIntent,CAMERA_REQUEST);

它打开相机,我可以拍照.但是当我点击保存按钮(s3中的勾选按钮)时出现问题,我的onActivityResult没有被调用,而是调用了A2的onDestroy方法.我在onActivityResult fn中完成的逻辑很少.

我已经阅读了Stackoverflow中的一些关于此的帖子,但我无法从中得到有用的输出.我的第二个活动(A2)有我的清单

android:configChanges="keyboardHidden|orientation|locale"
android:screenOrientation="portrait

注意:在HTC One X中我的onActivityResult fn被调用,但在我的S3中,第二个Activity(A2)被破坏了

Plz分享你对此的想法.提前致谢

我有两个选项"选择照片"和"拍照" - 我的选择照片功能完全正常,但拍照时出现问题.主要是保存的图像在保存后显示在图像视图中.

定义了我的照片位置:

public class photoActivity extends Activity {   
      private String photoPath;
      private ImageView imgView;
{...} 

我的相机听众:

bPicFromCam.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {

            String state = Environment.getExternalStorageState();

            if (Environment.MEDIA_MOUNTED.equals(state)) {

                long captureTime = System.currentTimeMillis();

                photoPath = Environment.getExternalStorageDirectory() + "/MYAPP" + captureTime + ".jpg";

                getPicFromCam(v);
            }
            else{

                Toast.makeText(getApplicationContext(),
                    "Sorry there is a problem accessing your SDCard, " +
                    "please select a picture from your gallery instead.", Toast.LENGTH_LONG).show();
            }

        }
    });

然后我的代码启动相机意图(注意photoPath是正确的):

    public void getPicFromCam(View view){

    System.out.println("photoPath: " + …

在我的应用程序中,我想从中选择图像Gallery并设置图像ListView.在我的ListView I have 16 rows. So when ever item click inListView open the gallery and set the image toListView中,. But my problem is some times afterstartActivityForResult(),oncreate()`方法被调用.这是onclick代码

Intent intent = new Intent(
                            Intent.ACTION_PICK,
                            android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                    intent.setType("image/*");
                    startActivityForResult(
                            Intent.createChooser(intent, "Select File"),
                            SELECT_PICTURE);

这是一个非常活跃的结果

public void onActivityResult(int requestcode, int resultcode, Intent data) {
    Log.e("result", "result");
    displayMetrics = this.getResources().getDisplayMetrics();
    Ew = displayMetrics.widthPixels;
    Eh = displayMetrics.heightPixels;

    switch (requestcode) {
    case SELECT_PICTURE:
        if (resultcode == RESULT_OK) { …

我有下一个问题：

当我尝试启动相机时，我可以拍摄照片，甚至将其保存在sdcard上，但是当我准备在设备上显示该照片的路径时，会出现错误。

我的全局变量为2（我使用了1，但最好使用2来确保这是一个奇怪的错误）：

    private File photofile;
private Uri mMakePhotoUri;

这是我的入门相机功能：

@SuppressLint("SimpleDateFormat")
public void farefoto(int num){
// For naming the picture
    SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd_HHmmss");
    String n = sdf.format(new Date());
    String fotoname = "Immagine-"+ n +".jpg";

//Going through files and  folders
    File photostorage = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
    File photostorage2 = new File(photostorage, "Immagini");
    System.out.println(photostorage+"\n"+photostorage2);
    photostorage2.mkdirs();
// My file (global)
    photofile = new File(photostorage2, fotoname);
    Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); //intent to start camera
// My URI (global)
    mMakePhotoUri = Uri.fromFile(photofile);
    new Bundle(); …
