对于
活动
，您必须在每次加载
活动
时声明并初始化该
底部栏

关于你的问题，我的答案是否定的

顺便说一句，你可以用它来帮助你解决这个问题

是时候学点新东西了，兄弟

编辑

您只在
1活动中带
Fragment
。让
BottomBar
进入
Activity
，而所有其他人都在
片段中查看和设置数据


试试看
 我用以下方法解决了这个问题：

1.使用底部导航栏创建一个基本活动


 package com.example.apple.bottomnavbarwithactivity;

 import android.content.Intent;
 import android.support.v7.app.AppCompatActivity;
 import android.os.Bundle;
 import android.util.Log;
 import android.widget.RadioButton;
 import android.widget.RadioGroup;

public class BaseActivity extends AppCompatActivity {


RadioGroup radioGroup1;
RadioButton deals;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_base);


    radioGroup1=(RadioGroup)findViewById(R.id.radioGroup1);
    deals = (RadioButton)findViewById(R.id.deals);
    radioGroup1.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener()
    {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId)
        {
            Intent in;
            Log.i("matching", "matching inside1 bro" + checkedId);
            switch (checkedId)
            {
                case R.id.matching:
                    Log.i("matching", "matching inside1 matching" +  checkedId);
                    in=new Intent(getBaseContext(),MatchingActivity.class);
                    startActivity(in);
                    overridePendingTransition(0, 0);
                    break;
                case R.id.watchList:
                    Log.i("matching", "matching inside1 watchlistAdapter" + checkedId);

                    in = new Intent(getBaseContext(), WatchlistActivity.class);
                    startActivity(in);
                    overridePendingTransition(0, 0);

                    break;
                case R.id.rates:
                    Log.i("matching", "matching inside1 rate" + checkedId);

                    in = new Intent(getBaseContext(),RatesActivity.class);
                    startActivity(in);
                    overridePendingTransition(0, 0);
                    break;
                case R.id.listing:
                    Log.i("matching", "matching inside1 listing" + checkedId);
                    in = new Intent(getBaseContext(), ListingActivity.class);
                    startActivity(in);
                    overridePendingTransition(0, 0);
                    break;
                case R.id.deals:
                    Log.i("matching", "matching inside1 deals" + checkedId);
                    in = new Intent(getBaseContext(), DealsActivity.class);
                    startActivity(in);
                    overridePendingTransition(0, 0);
                    break;
                default:
                    break;
            }
        }
    });
   }
 }

注意：确保正确处理反压操作。我没有为反压操作编写任何代码










你能提供屏幕截图吗？除了你的问题，Main3活动甚至不应该工作，因为如果你没有内容视图，findViewById就找不到视图。我的应用程序有五个主屏幕，都是活动，现在将这些活动更改为片段是非常困难和耗时的。是否有任何方法可以让我使用现有活动实现底部导航视图。您是否研究了
片段
？我认为这不会太难，也不会有太多的工作，只有5个屏幕：D.
Activity
和
Fragment
没有太大区别。您应该为以后的维护更换。设置活动如何？我可以把它放在底部导航栏吗？我正在实现这段代码，我不明白的是如何避免重新创建活动？我的意思是，我失去了活动状态，它是从头开始创建的。你可以保存活动状态签出这篇文章-
