@Override
public void onClick(View arg0) {
/* Intent i = new Intent(Tab1.this, ImageMain.class);
startActivity(i);*/
// selectImageFromGallery();
AlertDialog.Builder builder = new AlertDialog.Builder(Tab1.this);
builder.setMessage("Select Image From")
.setCancelable(true)
.setPositiveButton("camera", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
// start the image capture Intent
startActivityForResult(intent, CAMERA_REQUEST);
}
})
.setNegativeButton("gallary", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, RESULT_LOAD_IMAGE);
}
});
AlertDialog alert = builder.create();
alert.show();
}
});
听到我的onActiivityResult
Hear is my onActiivityResult
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// if the result is capturing Image
if (requestCode == CAMERA_REQUEST) {
if (resultCode == RESULT_OK) {
launchUploadActivity(true);
} else if (resultCode == RESULT_CANCELED) {
// user cancelled Image capture
Toast.makeText(getApplicationContext(),
"User cancelled image capture", Toast.LENGTH_SHORT)
.show();
} else {
// failed to capture image
Toast.makeText(getApplicationContext(),
"Sorry! Failed to capture image", Toast.LENGTH_SHORT)
.show();
}
}
else if(requestCode==RESULT_LOAD_IMAGE){
if (resultCode==RESULT_OK){
launchUploadActivity(true);
}
}
}
private void launchUploadActivity(boolean isImage){
Intent i = new Intent(Tab1.this,UploadAvtivity.class);
i.putExtra("filePath", fileUri.getPath());
i.putExtra("isImage", isImage);
startActivity(i);
}
推荐答案
这是通过默认相机拍摄照片的代码片段（这里我实现了Intent来获取图像）。之后将其存储到SD卡（这里将创建一个新文件并存储新拍摄的图像）;如果您不想存储，则从代码中删除保存部分。之后，您可以使用文件路径进行上传。然后你可以引用它并改变以获得你想要的路径。
Here is the Code piece for Taking a Picture through Default Camera (here I implemented Intent to to fetch the image). After that store it to SD card(here a new file will be created and the newly taken image will be stored ); and if you don't want to store then remove the saving part from code. After that you can use the file path for your upload purpose. You can then refer it and change to get the path as your wish.
在课程区域放这些行
final int TAKE_PHOTO_REQ = 100;
String file_path = Environment.getExternalStorageDirectory()
+ "/recent.jpg";//Here recent.jpg is your image name which will going to take
之后通过将这些行放入调用方法来调用相机。
After that invoke the camera by putting these line in calling method.
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, TAKE_PHOTO_REQ);
然后在您的Activity中添加此方法以获取图片并将其保存到SD卡并且您可以调用你的上传方法从这里通过了解它的路径来上传图片。
then add this method in your Activity to get the picture and save it to sd card and you can invoke your upload method from here to upload the image by knowing its path.
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case TAKE_PHOTO_REQ: {
if (resultCode == TakePicture.RESULT_OK && data != null) {
Bitmap srcBmp = (Bitmap) data.getExtras().get("data");
// ... (process image if necesary)
imageView.setImageBitmap(srcBmp);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
srcBmp.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
// you can create a new file name "test.jpg" in sdcard folder.
File f = new File(file_path);
try {
f.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// write the bytes in file
FileOutputStream fo = null;
try {
fo = new FileOutputStream(f);
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
fo.write(bytes.toByteArray());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// remember close de FileOutput
try {
fo.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.e("take-img", "Image Saved to sd card...");
// Toast.makeText(getApplicationContext(),
// "Image Saved to sd card...", Toast.LENGTH_SHORT).show();
break;
}
}
}
}
