我需要采取picture与camera， 保存picture， 显示ImageView当我点击Imageview显示全屏 mode .
将来需要发送picture to the internet.
这就是我所做的：
public void captureImage(View v) {
Intent camera_intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(camera_intent, CAMERA_PIC_REQUEST);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
imgView = (ImageView) findViewById(R.id.formRegister_picture);
imgView.setScaleType(ImageView.ScaleType.CENTER_CROP);
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode){
case CAMERA_PIC_REQUEST:
if(resultCode==RESULT_OK){
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
imgView.setImageBitmap(thumbnail);
}
}
}
您可以通过在代码中添加以下行来调用相机活动：
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
private static int RESULT_IMAGE_CLICK = 1;
cameraImageUri = getOutputMediaFileUri(1);
// set the image file name
intent.putExtra(MediaStore.EXTRA_OUTPUT, cameraImageUri);
startActivityForResult(intent, RESULT_IMAGE_CLICK);
现在创建文件Uri因为在某些 Android 手机中你会得到null数据输入return
所以这是获取图像的方法URI :
/** Create a file Uri for saving an image or video */
private static Uri getOutputMediaFileUri(int type) {
return Uri.fromFile(getOutputMediaFile(type));
}
/** Create a File for saving an image or video */
private static File getOutputMediaFile(int type) {
// Check that the SDCard is mounted
File mediaStorageDir = new File(
Environment.getExternalStorageDirectory(), Environment.DIRECTORY_PICTURES);
// Create the storage directory(MyCameraVideo) if it does not exist
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
Log.e("Item Attachment",
"Failed to create directory MyCameraVideo.");
return null;
}
}
java.util.Date date = new java.util.Date();
String timeStamp = getTimeStamp();
File mediaFile;
if (type == 1) {
// For unique video file name appending current timeStamp with file
// name
mediaFile = new File(mediaStorageDir.getPath() + File.separator +abc+ ".jpg");
} else {
return null;
}
return mediaFile;
}
用于检索单击的图像：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == RESULT_IMAGE_CLICK) {
// Here you have the ImagePath which you can set to you image view
Log.e("Image Name", cameraImageUri.getPath());
Bitmap myBitmap = BitmapFactory.decodeFile(cameraImageUri.getPath());
yourImageView.setImageBitmap(myBitmap);
// For further image Upload i suppose your method for image upload is UploadImage
File imageFile = new File(cameraImageUri.getPath());
uploadImage(imageFile);
}
}
}
