Android Studio-如何关闭对话框

萨马德

只是想知道选择一个选项后如何关闭对话框。

这是代码

public boolean onOptionsItemSelected(MenuItem item) {
    super.onOptionsItemSelected(item);

    if (item.getItemId() == R.id.launch_voip_call) {
        Utils.startCall(this, contact);
        return true;
    } 
    else if(item.getItemId() == R.id.launch_attachment){

        AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
        dialogBuilder.setCancelable(true);

        View choiceView = getLayoutInflater().inflate(R.layout.dialog_image_source_chooser, null);

        ImageButton cameraButton = (ImageButton) choiceView.findViewById(R.id.cameraButton);

        ImageButton galleryButton = (ImageButton) choiceView.findViewById(R.id.galleryButton);

        cameraButton.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                Intent cameraIntent = new Intent(SingleConversationActivity.this, CameraActivity.class);
                cameraIntent.putExtra("EXTRA_CONTACT_JID", contact.getJid());
                startActivity(cameraIntent);

            }
        });

AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(YourActivity.this);

                LayoutInflater inflater = YourActivity.this.getLayoutInflater();
                View dialogView = inflater.inflate(R.layout.dialog_image_source_chooser, null);
                dialogBuilder.setView(dialogView);

               ImageButton cameraButton = (ImageButton) dialogView.findViewById(R.id.cameraButton);

    ImageButton galleryButton = (ImageButton) dialogView.findViewById(R.id.galleryButton);


                final AlertDialog alertDialog = dialogBuilder.create();
                alertDialog.show();

                cameraButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {

                         alertDialog.dismiss();
                         Intent cameraIntent = new Intent(SingleConversationActivity.this, CameraActivity.class);
            cameraIntent.putExtra("EXTRA_CONTACT_JID", contact.getJid());
            startActivity(cameraIntent);

                    }
                });
