Question

虽然在按下空档按钮时没有提及关闭或关闭我的对话框，但我的应用程序仍然感觉需要在按下时关闭对话框。

任何想法为什么？

dialogBox = (AlertDialog) dialogBoxHandler.locationDialog();
dialogBox.setButton(DialogInterface.BUTTON_NEUTRAL, "Use Current Location", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    EditText latitude = (EditText) dialogBox.findViewById(R.id.dl_et_latitude);
                    EditText longitude = (EditText) dialogBox.findViewById(R.id.dl_et_longitude);
                    LocationManager lm = (LocationManager) MessageSelection.this.getSystemService(Context.LOCATION_SERVICE);
                    try {
                        Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
                        double currentLongitude = location.getLongitude();
                        double currentLatitude = location.getLatitude();
                        latitude.setText(Double.toString(currentLatitude));
                        longitude.setText(Double.toString(currentLongitude));
                        Log.d(TAG, "Latitude " + currentLatitude + "  Longitude " + currentLongitude);
                    } catch (SecurityException e){
                        Log.d(TAG, e.toString());
                    }
                }
            });
 dialogBox.show();

原来需要一个OnShowListener，它必须在其中定义onClickListener。当在使用DialogBuilder时尝试定义中性按钮功能或在创建对话框之后（以及在显示对话框之前）设置按钮功能时，这将不起作用。

dialogBuilder.setView(inflater.inflate(R.layout.dialog_location, null))
            .setNeutralButton("Use Current Location", null);

final AlertDialog locationDialog = dialogBuilder.create();

locationDialog.setOnShowListener(new DialogInterface.OnShowListener() {

        @Override
        public void onShow(DialogInterface dialog) {

            Button button = ((AlertDialog) dialog).getButton(AlertDialog.BUTTON_NEUTRAL);
            button.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View view) {
                    EditText latitude = (EditText) locationDialog.findViewById(R.id.dl_et_latitude);
                    EditText longitude = (EditText) locationDialog.findViewById(R.id.dl_et_longitude);
                    LocationManager lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
                    try {
                        Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
                        double currentLongitude = location.getLongitude();
                        double currentLatitude = location.getLatitude();
                        latitude.setText(Double.toString(currentLatitude));
                        longitude.setText(Double.toString(currentLongitude));
                        Log.d(TAG, "Latitude " + currentLatitude + "  Longitude " + currentLongitude);
                    } catch (SecurityException e){
                        Log.d(TAG, e.toString());
                    }
                }
            });
        }
    });

AlertDialog中的每个按钮都会将其关闭只有你这样做：

mAlertDialog.setView(mButton);

mButton点击不会解雇它

Answer 3

所有AlertDialog按钮都会将其关闭。如果您需要一个按钮并且希望AlertDialog不被忽略，则必须使用内部按钮的自定义视图。

AlertDialog中性按钮解除对话框
