本文介绍了从捕获的画廊和放大器形象;摄像头的Android的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
第一件事，我知道这是重复的问题，但我没有问题，从画廊或照相机拍摄的图像。我对虚拟项目中创建到这里检查我的code它的正常工作 但是，当我在我的项目和功放使用相同的code;在这里它不工作，即使我没有得到任何错误 当我开始活动导致它被取消，但我仍可以看到图库＆放图像;我可以从相机拍摄的图像。
First thing I know this is repeated question but I don't have problem in capturing image from gallery or camera. I created on dummy project to check my code here it's working fine But when I used same code in my project & here it's not working even I didn't get any error as soon as I start activity for result it get cancelled but still I can see images from gallery & I can capture image from camera.
当我检查我的logcat发现以下警告不知道为什么它的未来和放大器;如何可以解决这件事情
When I checked logcat I found following warning don't know why it's coming & how I can fix this thing
W/NetworkConnectivityListener(2399): onReceived() called with CONNECTED and Intent { act=android.net.conn.CONNECTIVITY_CHANGE flg=0x10000000 (has extras) }
编辑： - 增加了code
-- Added Code
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.camera:
//define the file-name to save photo taken by Camera activity
String fileName = "new-photo-name.jpg";
//create parameters for Intent with filename
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
values.put(MediaStore.Images.Media.DESCRIPTION,"Image capture by camera");
//imageUri is the current activity attribute, define and save it for later usage (also in onSaveInstanceState)
imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
//create new Intent
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, PICK_Camera_IMAGE);
return true;
case R.id.gallery:
try {
Intent gintent = new Intent();
gintent.setType("image/*");
gintent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
Intent.createChooser(gintent, "Select Picture"),
PICK_IMAGE);
} catch (Exception e) {
Toast.makeText(getApplicationContext(),
e.getMessage(),
Toast.LENGTH_LONG).show();
Log.e(e.getClass().getName(), e.getMessage(), e);
}
return true;
}
return false;
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case PICK_IMAGE:
if (resultCode == Activity.RESULT_OK) {
Uri selectedImageUri = data.getData();
String filePath = null;
try {
// OI FILE Manager
String filemanagerstring = selectedImageUri.getPath();
// MEDIA GALLERY
String selectedImagePath = getPath(selectedImageUri);
if (selectedImagePath != null) {
filePath = selectedImagePath;
} else if (filemanagerstring != null) {
filePath = filemanagerstring;
} else {
Toast.makeText(getApplicationContext(), "Unknown path",
Toast.LENGTH_LONG).show();
Log.e("Bitmap", "Unknown path");
}
if (filePath != null) {
decodeFile(filePath);
} else {
bitmap = null;
}
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Internal error",
Toast.LENGTH_LONG).show();
Log.e(e.getClass().getName(), e.getMessage(), e);
}
}
break;
case PICK_Camera_IMAGE:
if (resultCode == RESULT_OK) {
//use imageUri here to access the image
Toast.makeText(this, "Picture was taken", Toast.LENGTH_SHORT).show();
Uri selectedImageUri = imageUri;
String filePath = null;
try {
// OI FILE Manager
String filemanagerstring = selectedImageUri.getPath();
// MEDIA GALLERY
String selectedImagePath = getPath(selectedImageUri);

Toast.LENGTH_LONG).show();
Log.e(e.getClass().getName(), e.getMessage(), e);
}
} else if (resultCode == RESULT_CANCELED) {
Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT).show();
}
break;
}

推荐答案
看看 LinderdaumEngineActivity.java 从我的项目的 Linderdaum引擎：
从相机拍摄的图像：
public void CapturePhoto( String FileName )
{
try
{
File f = new File(FileName);
if ( f.exists() && f.canWrite() ) f.delete();
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,Uri.fromFile(f));
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, CAPTURE_IMAGE_CALLBACK);
}
catch ( ActivityNotFoundException e )
{
Log.e( TAG, "No camera: " + e );
}
catch ( Exception e )
{
Log.e( TAG, "Cannot make photo: " + e );
}
}
从库中打开图像：
Open image from gallery:
public static void OpenImage()
{
try
{
Intent intent = new Intent( Intent.ACTION_GET_CONTENT );
intent.setType( "image/*" );
startActivityForResult( intent, SELECT_PICTURE_CALLBACK );
}
catch ( ActivityNotFoundException e )
{
Log.e( TAG, "No gallery: " + e );
}
}
另外，不要忘了权限添加到您的清单：
Also, do not forget to add permissions to your manifest:
<uses-feature android:name="android.hardware.camera" android:required="false"/>
<uses-permission android:name="android.permission.CAMERA" android:required="false"/>
