如何在我的Android应用中添加一个按钮，将图片视图中的图片仅发布到脸书页？
此按钮此处将图像分享给所有不需要的媒体
这里init是执行任务的方法。
以下是我的尝试：
`private void init(){
File dir = new File("/sdcard/Testing/");
try {
if (dir.mkdir()) {
System.out.println("Directoryted");
} else {
System.out.println("Directoryot created");
}
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_click:
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent,CAMERA_REQUEST);
break;
case R.id.btn_share:
Bitmap bitmap1 = loadBitmapFromView(relativeLayout, relativeLayout.getWidth(), relativeLayout.getHeight());
saveBitmap(bitmap1);
String str_screenshot = "/sdcard/Testing/" + "testing" + ".jpg";
fn_share(str_screenshot);
break;
}
}
public void saveBitmap(Bitmap bitmap) {
File imagePath = new File("/sdcard/Testing/" + "testing" + ".jpg");
FileOutputStream fos;
try {
fos = new FileOutputStream(imagePath);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
fos.flush();
fos.close();
Log.e("ImageSave", "Saveimage");
} catch (FileNotFoundException e) {
Log.e("GREC", e.getMessage(), e);
} catch (IOException e) {
Log.e("GREC", e.getMessage(), e);
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
image.setImageBitmap(photo);
}
}
public static Bitmap loadBitmapFromView(View v, int width, int height) {
Bitmap b = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
v.draw(c);
return b;
}
public void fn_share(String path) {
File file = new File("/mnt/" + path);
Bitmap bmp = BitmapFactory.decodeFile(file.getAbsolutePath());
Uri uri = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(intent, "Share Image"));
}`
