Android 对话框在任何物理按键时关闭

Android dialog closes on any physical keypress

我有这个对话框,只有一个文本视图,没有按钮。它显示一些信息,我需要更改左右按键的信息。不幸的是,对话框关闭任何键。 MainActivity中这段代码调用对话框(省略多余代码)

@Override
public boolean dispatchKeyEvent(KeyEvent event) {
    if (event.getKeyCode() == KeyEvent.KEYCODE_MENU) {
        if (event.getAction() == KeyEvent.ACTION_UP) {
            InfoDialog infoDialog = new InfoDialog();
            infoDialog.showDialog(this,currentDateAndTime,chn);
            return true;
        }
    }
    return super.dispatchKeyEvent(event);
}

这是对话代码

public class InfoDialog {
    private int counter = 0;
    private Dialog dialog;
    
    public void showDialog(final Activity activity, final String DateTime, final ChannelList.Channel chn){
        dialog = new Dialog(activity);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setCancelable(false);
        dialog.setContentView(R.layout.info_dialog);

        counter = 0;
        setDialogText(chn,DateTime,counter);

        dialog.setOnKeyListener(new DialogInterface.OnKeyListener() {
            @Override
            public boolean onKey(DialogInterface dialogInterface, int i, KeyEvent keyEvent) {
                if (keyEvent.getKeyCode() == KeyEvent.KEYCODE_DPAD_LEFT) {
                    if (keyEvent.getAction() == KeyEvent.ACTION_UP) {
                        if (counter>0) counter--;
                        setDialogText(chn,DateTime,counter);
                        return true;
                    }
                }
                if (keyEvent.getKeyCode() == KeyEvent.KEYCODE_DPAD_RIGHT) {
                    if (keyEvent.getAction() == KeyEvent.ACTION_UP) {
                        if (counter<chn.infoText.size()-1) counter++;
                        setDialogText(chn,DateTime,counter);
                        return true;
                    }
                }
                dialog.dismiss();
                return false;
            }
        });

        dialog.show();

    }
}

当我按下任何按钮时,对话框关闭,即使 onKey 已被调用。 我错过了什么?如何仅处理我的对话框的按键? (其他对话框可能使用相同的按键进行不同的操作)

好吧,在 InfoDialog 中您正在设置 DialogInterface.OnKeyListener 并且在 onKey 方法的底部您正在调用 dialog.dismiss(),尝试删除此行...(并且 return true 对于任何情况)
