如何让搜索按钮从关闭一个AlertDialog？ [英] How to keep search button from closing an AlertDialog?

问题描述

如果我创建一个独立的alertdialog与建筑商（未连接到活动/视图）我怎能搜索按钮从导致alertdialog关闭？

If I create a standalone alertdialog with the builder (not connected to the activity/view) how can I keep the search button from causing the alertdialog to close?

感谢。

我也面临同样的问题，同时显示最终用户许可协议对话框。 它是由setOnKeyListener解决。

I'm also faced the same problem while showing EULA Dialog. It was solved by setOnKeyListener.

下面是解决方案：

                AlertDialog.Builder builder = new AlertDialog.Builder(mActivity)
                    .setTitle(title)
                    .setMessage(message)
                    .setPositiveButton(android.R.string.ok, new Dialog.OnClickListener() {

                        @Override
                        public void onClick(DialogInterface dialogInterface, int i) {
                            SharedPreferences.Editor editor = prefs.edit();
                            editor.putInt(Constants.EULA_VERSION, versionInfo.versionCode);
                            editor.commit();
                            dialogInterface.dismiss();
                        }
                    })
                    .setNegativeButton(android.R.string.cancel, new Dialog.OnClickListener() {

                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            // Close the activity once the EULA is declined.
                            mActivity.finish(); 
                        }

                    });

            //To avoid skipping EULA screen through search & menu button.
            builder.setOnKeyListener(new DialogInterface.OnKeyListener() {
                public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {
                    if (keyCode < KeyEvent.KEYCODE_DPAD_UP || keyCode > KeyEvent.KEYCODE_DPAD_CENTER) 
                    {
                        return true;
                    }
                    else
                        return false;
                }
            });
            builder.create().show();
