Android的我怎么能说相机或画廊意图一起 [英] Android How can I call Camera or Gallery Intent Together
本文介绍了Android的我怎么能说相机或画廊意图一起的处理方法，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
如果我想从本机相机拍摄的图像，我可以做的：
If I want to capture image from native camera, I can do:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, IMAGE_CAPTURE);
如果我想从画廊的形象，我可以做的：
If I want to get image from gallery, I can do:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
我想知道怎样才能把上述两者结合起来。
这意味着获取图像从画廊或拍摄照片
I am wondering how can put the above two together.
That means GET IMAGE FROM GALLERY OR CAPTURE PHOTO
有没有例如code办呢？ 谢谢你。
Is there any example code to do it? Thanks.
推荐答案
如果你想拍照，从摄像机或图库意图一起，然后检查下面的链接。同样的问题也张贴在这里。
If you want to take picture from Camera or Gallery Intent Together, Then check below link. Same question also posted here.

更新时间是code：
检查以下code，在这种code，只要你想进入列表视图不一样的，但它给了DialogBox的选项从GALLARY或相机选择图像。
check below code, In this code not same as you want into listview, but it gives the option in the dialogBox choose image from Gallary OR Camera.
public class UploadImageActivity extends Activity {
ImageView img_logo;
protected static final int CAMERA_REQUEST = 0;
protected static final int GALLERY_PICTURE = 1;
private Intent pictureActionIntent = null;
Bitmap bitmap;
String selectedImagePath;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main1);
img_logo= (ImageView) findViewById(R.id.imageView1);
img_logo.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
startDialog();
}
});
}
private void startDialog() {
AlertDialog.Builder myAlertDialog = new AlertDialog.Builder(
getActivity());
myAlertDialog.setTitle("Upload Pictures Option");
myAlertDialog.setMessage("How do you want to set your picture?");
myAlertDialog.setPositiveButton("Gallery",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
Intent pictureActionIntent = null;
pictureActionIntent = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(
pictureActionIntent,
GALLERY_PICTURE);
}
});
myAlertDialog.setNegativeButton("Camera",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
Intent intent = new Intent(
MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment
.getExternalStorageDirectory(), "temp.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(f));
startActivityForResult(intent,
CAMERA_REQUEST);
}
});
myAlertDialog.show();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
bitmap = null;
selectedImagePath = null;
if (resultCode == RESULT_OK && requestCode == CAMERA_REQUEST) {
File f = new File(Environment.getExternalStorageDirectory()
.toString());
for (File temp : f.listFiles()) {
if (temp.getName().equals("temp.jpg")) {
f = temp;
break;
}
}
if (!f.exists()) {
Toast.makeText(getBaseContext(),
"Error while capturing image", Toast.LENGTH_LONG)
.show();
return;
}
try {
bitmap = BitmapFactory.decodeFile(f.getAbsolutePath());
bitmap = Bitmap.createScaledBitmap(bitmap, 400, 400, true);
int rotate = 0;
try {
ExifInterface exif = new ExifInterface(f.getAbsolutePath());
int orientation = exif.getAttributeInt(
ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 270;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
break;
}
} catch (Exception e) {
e.printStackTrace();
}
Matrix matrix = new Matrix();
matrix.postRotate(rotate);
bitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(),
bitmap.getHeight(), matrix, true);
img_logo.setImageBitmap(bitmap);
//storeImageTosdCard(bitmap);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} else if (resultCode == RESULT_OK && requestCode == GALLERY_PICTURE) {
if (data != null) {
Uri selectedImage = data.getData();
String[] filePath = { MediaStore.Images.Media.DATA };
Cursor c = getContentResolver().query(selectedImage, filePath,
null, null, null);
c.moveToFirst();
int columnIndex = c.getColumnIndex(filePath[0]);
selectedImagePath = c.getString(columnIndex);
c.close();
if (selectedImagePath != null) {
txt_image_path.setText(selectedImagePath);
}
bitmap = BitmapFactory.decodeFile(selectedImagePath); // load
// preview image
bitmap = Bitmap.createScaledBitmap(bitmap, 400, 400, false);
img_logo.setImageBitmap(bitmap);
} else {
Toast.makeText(getApplicationContext(), "Cancelled",
Toast.LENGTH_SHORT).show();
}
}
}
}
另外补充pemission：
Also add pemission:
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature
android:name="android.hardware.camera.autofocus"
android:required="false" />
<uses-feature
android:name="android.hardware.camera"
android:required="false" />
店面形象，以SD卡：
store Image to sdcard:
private void storeImageTosdCard(Bitmap processedBitmap) {
try {
// TODO Auto-generated method stub
OutputStream output;
// Find the SD Card path
File filepath = Environment.getExternalStorageDirectory();
// Create a new folder in SD Card
File dir = new File(filepath.getAbsolutePath() + "/appName/");
dir.mkdirs();
String imge_name = "appName" + System.currentTimeMillis()
+ ".jpg";
// Create a name for the saved image
File file = new File(dir, imge_name);
if (file.exists()) {
file.delete();
file.createNewFile();
} else {
file.createNewFile();
}
try {
output = new FileOutputStream(file);
// Compress into png format image from 0% - 100%
processedBitmap
.compress(Bitmap.CompressFormat.PNG, 100, output);
output.flush();
output.close();
int file_size = Integer
.parseInt(String.valueOf(file.length() / 1024));
System.out.println("size ===>>> " + file_size);
System.out.println("file.length() ===>>> " + file.length());
selectedImagePath = file.getAbsolutePath();
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
