Question

我创建了一个选择器，用于从文件中选择图像或制作图片。

我使用的代码在Nexus 5上工作正常，但是当我在Samsung S5上试用时，选择器不会显示相机图标。

public Intent makePhotoIntent(String title, Context ctx, String uniqueImageId){

        //Build galleryIntent
        Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        galleryIntent.setType("image/*");

        //Create chooser
        Intent chooser = Intent.createChooser(galleryIntent,title);

        if (checkexCameraHardware()){
            Intent  cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            mTempImage = null;
            try {
                mTempImage = createImageFile(uniqueImageId);
            } catch (IOException e) {
                e.printStackTrace();
            }

            if (mTempImage != null){
                cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(mTempImage)); //add file ure (photo is saved here)
                Intent[] extraIntents = {cameraIntent};
                chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
            }
        }
        return chooser;
    }

Samsung Nexus

当我更改将意图添加到选择器的顺序时，三星设备会显示相机，但只显示android-system作为文件选项。

public Intent makePhotoIntent(String title, Context ctx, String uniqueImageId){

        //Build galleryIntent
        Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        galleryIntent.setType("image/*");

        //Create chooser
        Intent chooser = Intent.createChooser(galleryIntent,title);

        if (checkexCameraHardware()){
            Intent  cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            mTempImage = null;
            try {
                mTempImage = createImageFile(uniqueImageId);
            } catch (IOException e) {
                e.printStackTrace();
            }

            if (mTempImage != null){
                cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(mTempImage)); //add file ure (photo is saved here)

                //I have to re-create the chooser here or the Samsung will not show the 'camera' icons.
                //I have to add the cameraIntent first.
                chooser = Intent.createChooser(cameraIntent,title);
                Intent[] extraIntents = {galleryIntent};

                //Intent[] extraIntents = {cameraIntent};
                chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
            }
        }
        return chooser;
    }

Samsung Nexus

理想情况下，当我首先添加图库意图时，我希望三星设备显示与Nexus相同的设备。但是我无法让它发挥作用。

Answer 1

如果额外意图（Intent.EXTRA_INITIAL_INTENTS）有多个意图匹配，则会在＆＃34; Android系统＆＃34; 下显示所有意图匹配。当您点击＆＃34; Android系统＆＃34;时，它将打开另一个具有所有这些意图匹配的选择器。
所以，在你为samsung设备拍摄的第一张截图中，相机确实出现了 - 它刚好在＆＃34; Android Systeem＆＃34; （单击此按钮将显示所有相机意图匹配）。
如果你使galleryIntent更多而不是相机意图，它会将所有与画廊相关的意图组合在＆＃34; Android Systeem＆＃34; （如您在samsung设备的第二个屏幕截图中所示）

我想如果用户不知道这个＆＃34; Android Systeem＆＃34;是！

使用以下解决方案，您可以直接将每一个添加到chooser

在您的第二个代码段中，替换

Intent[] extraIntents = {galleryIntent};
chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);

with：

List<Intent> galleryIntents = new ArrayList<Intent>();
PackageManager pm = getApplicationContext().getPackageManager();
for (ResolveInfo ri: pm.queryIntentActivities(galleryIntent, PackageManager.MATCH_DEFAULT_ONLY)) {
    Intent intent = pm.getLaunchIntentForPackage(ri.activityInfo.packageName);
    intent.setAction(Intent.ACTION_PICK);
    galleryIntents.add(intent); 
}
chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, galleryIntents.toArray(new Parcelable[] {}));

这会将每个匹配的意图直接手动添加到您的chooser

Answer 2

试试这种方式，希望这可以帮助您解决问题

请按照以下步骤操作，这是从图库和相机中选择图像的最佳和最简单的方法，

步骤1.声明全局变量

public static final int rcCC = 33;
boolean isCC = false;

第2步。复制这些方法并粘贴代码

void picPhoto() {
    String str[] = new String[] { "Camera", "Gallery" };
    new AlertDialog.Builder(getActivity()).setItems(str,
            new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    performImgPicAction(which);
                }
            }).show();
}

void performImgPicAction(int which) {
    Intent in;
    if (which == 1) {
        in = new Intent(
                Intent.ACTION_PICK,
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    } else {
        in = new Intent();
        in.setAction(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    }
    startActivityForResult(
            Intent.createChooser(in, "Select profile picture"), which);
}

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


        try {
            if (rcCC == requestCode) {
                getActivity();
                if (resultCode == Activity.RESULT_OK) {
                    isCC = true;

                }
            } else {
                getActivity();
                if (resultCode == Activity.RESULT_OK) {
                    BitmapFactory.Options option = new BitmapFactory.Options();
                    option.inDither = false;
                    option.inPurgeable = true;
                    option.inInputShareable = true;
                    option.inTempStorage = new byte[32 * 1024];
                    option.inPreferredConfig = Bitmap.Config.RGB_565;
                    if (Build.VERSION.SDK_INT < 19) {
                        Uri selectedImageURI = data.getData();
                        uImage = BitmapFactory.decodeFile(Common.getPath(
                                selectedImageURI, getActivity()), option);
                    } else {

                        ParcelFileDescriptor pfd;
                        try {
                            pfd = context
                                    .getContentResolver()
                                    .openFileDescriptor(data.getData(), "r");
                            FileDescriptor fileDescriptor = pfd
                                    .getFileDescriptor();

                            uImage = BitmapFactory.decodeFileDescriptor(
                                    fileDescriptor, null, option);
                            pfd.close();

                        } catch (FileNotFoundException e) {
                            e.printStackTrace();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }
                    try {
                        ivProfile_image.setImageBitmap(uImage);

                    } catch (Exception e) {
                        e.printStackTrace();
                    }

                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

}

步骤3.调用方法，在那里选择图片并显示对话框

  picPhoto();

第4步。

在清单文件中设置用户权限

     <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
     <uses-permission android:name="android.permission.CAMERA" />

Answer 3

尝试这种方式，我希望它适合你，我检查三星galaxy tab 2它显示相机选项

声明你的意图

  Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    galleryIntent.setType("image/*");

    //Create chooser
    Intent chooser = Intent.createChooser(galleryIntent,title);

        Intent  cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        fileUri = getOutputMediaFileUri(uniqueImageId);
            cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, fileUri); //add file ure (photo is saved here)
            Intent[] extraIntents = {cameraIntent};
            chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);

            startActivityForResult(chooser, Constants.SEND_IMAGE_FROM_CEMERA);

和getOutputMediaFileUri（uniqueImageId）方法返回你的Uri图像

getOutputMediaFileUri(String uniqueImageId){

        File mediaStorageDir = new File(
                Environment
                        .getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
                "IMAGE_DIRECTORY_NAME");

        // Create the storage directory if it does not exist
        if (!mediaStorageDir.exists()) {
            if (!mediaStorageDir.mkdirs()) {
                return null;
            }
        }


        File mediaFile;
            mediaFile = new File(mediaStorageDir.getPath() + File.separator
                    + "IMG_" + uniqueImageId + ".jpg");

        return Uri.fromFile(mediaFile);
}

具有相机意图和图像选择器意图的选择器
