我是靠谱客的博主尊敬网络，最近开发中收集的这篇文章主要介绍安卓按键顺序检测触发隐藏入口的实现方式，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

需求场景：在AndroidTv上隐藏式调出不开放给用户的开发模式或者工厂模式。

思路：在设置或者特定的页面下，按指定顺序按下遥控按键触发。

封装类如下：

import android.util.Log;
import android.view.KeyEvent;

/***
 * LankyBin 2022.08.19
 * 隐藏入口
 * 组合顺序按键调用隐藏动作
 */
public class HiddenEntrance {
    private final String TAG = this.getClass().getSimpleName();
    private final int[] mPassword;

    public HiddenEntrance(int[] password) {
        mPassword = password;
    }

    private OnPasswordCheckedListener mListener = new OnPasswordCheckedListener() {
        @Override
        public void onPasswordChecked(boolean passed) {
            Log.d(TAG, "onPasswordChecked: " + passed + " TO DO?");
        }
    };
    private int mPwdNo = 0;

    public boolean checkPassword(int keyCode) {
        boolean ret = false;
        if (keyCode == KeyEvent.KEYCODE_UNKNOWN) {
            return false;
        }
        if (keyCode == mPassword[mPwdNo]) {
            ++mPwdNo;
        } else {
            mPwdNo = 0;
        }
        if (mPwdNo == mPassword.length) {
            ret = true;
            mPwdNo = 0;
        }
        mListener.onPasswordChecked(ret);
        return ret;
    }

    public void setOnPasswordCheckedListener(OnPasswordCheckedListener listener) {
        mListener = listener;
    }

    public interface OnPasswordCheckedListener {
        void onPasswordChecked(boolean passed);
    }
}

调用方式demo：

    private static final int[] PASSWORD = {
            KeyEvent.KEYCODE_DPAD_UP,
            KeyEvent.KEYCODE_DPAD_LEFT,
            KeyEvent.KEYCODE_MENU,
            KeyEvent.KEYCODE_DPAD_DOWN,
            KeyEvent.KEYCODE_DPAD_RIGHT
    };

    private final HiddenEntrance mHiddenEntrance = new HiddenEntrance(PASSWORD);

    @Override
    protected void onResume() {
        mHiddenEntrance.setOnPasswordCheckedListener(new HiddenEntrance.OnPasswordCheckedListener() {
            @Override
            public void onPasswordChecked(boolean passed) {
                if (passed) {
                    Log.d(TAG, "onPasswordChecked: todo");
                    //做你想做的事
                }
            }
        });
        super.onResume();
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (event.getAction() == KeyEvent.ACTION_DOWN) {

            mHiddenEntrance.checkPassword(keyCode);

        }
        return super.onKeyDown(keyCode, event);
    }
