Android 2.2的SDK - Droid X的摄像头活动未正常完成 [英] Android 2.2 SDK - Droid X Camera Activity doesn't finish properly

问题描述

我注意到了默认的摄像头的活动我请一个Droid X的不同，看起来比那个在我的Droid和Nexus One的。选择OK大家对Droid和Nexus One后，该活动会完成 - 在Droid X有一个完成按钮（这需要你背对着镜头，而不是结束的活动），并获得到的唯一途径屏幕我想是打了后退按钮。

下面是在Android 2.2 / 2.3，工程类，但不适合的Droid X的：

解决方案

多德...这只是一个错误。我有同样的问题，有没有办法解决办法的。它有时工作，有时没有。我问了摩托罗拉的人寻求帮助，他们说，有一个为Android的那些图像的支持。

I noticed the default camera activity I call on a Droid X is different looking than the one on my Droid and Nexus One. After selecting "OK" on the Droid and Nexus One, the activity would finish - the Droid X has a "Done" button (which takes you back to the Camera, instead of finishing the activity), and the only way to get to the screen I want is to hit the "Back" button.

Here is the class that works on Android 2.2/2.3, but not for Droid X's:

package com.android.xxx;

import java.io.File;

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import android.view.Window;

public class CameraView extends MenusHolder {

    protected String _path;
    protected boolean _taken;

    protected static final String PHOTO_TAKEN = "photo_taken";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.create_event_view);
        /*
         * save to sd
         */
        File imageDirectory = new File(
                Environment.getExternalStorageDirectory() + "/MyPath/");
        imageDirectory.mkdirs();
        /*
         * temp image overwrites each time for space
         */
        _path = Environment.getExternalStorageDirectory()
                + "/MyPath/temporary_image.jpg";
        startCameraActivity();
    }

    protected void startCameraActivity() {
        File file = new File(_path);
        Uri outputFileUri = Uri.fromFile(file);

        Intent intent = new Intent(
                android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
        startActivityForResult(intent, 0);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (resultCode) {
        case 0:
            setResult(5);
            finish();
            break;
        case -1:
            onPhotoTaken();
            break;
        }
    }

    protected void onPhotoTaken() {
        _taken = true;
        setResult(0);
        finish();
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        outState.putBoolean(CameraView.PHOTO_TAKEN, _taken);
    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        if (savedInstanceState.getBoolean(CameraView.PHOTO_TAKEN)) {
            onPhotoTaken();
        }
    }

}

解决方案

Dude... it's just a bug. I had the same problem and there's no way to workaround that. It sometimes work, and sometimes it does not. I asked the Motorola's guy for help and they said that there's no support for those Android images.
