Android 底部導航欄以及導航欄角標顯示，使用LinearLayout+Fragment實作-有解無憂

Android 底部導航欄以及角標顯示，使用LinearLayout+Fragment實作

- 1、自定義按鈕控制元件
- 2、自定義底部欄
- 3、使用

看過網上很多大神寫的關于底部導航欄的實作方式，但是總感覺用的不是那么隨意，作為一個專業的出色的自學者，要借鑒大神的，實作自己的，有何不足之處，歡迎大家批評指正，
特點：可以自由設定每個底部欄按鈕的樣式，大小
MyBottomForLinearLayout中的setMarkerNum方法設定角標
如：bottomForLinearLayout.setMarkerNum(5,122);
5是導航欄第幾個按鈕，122是設定的數字，超過99顯示99

在這里插入圖片描述

1、自定義按鈕控制元件

3、使用

邏輯代碼 activity_start_expense

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    tools:context="erp.expense.StartExpenseActivity">
    <FrameLayout
        android:id="@+id/start_activity_framelayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/start_activity_mylayout"
        />
    <erp.mylib.mystyle.from.MyBottomForLinearLayout
        android:id="@+id/start_activity_mylayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:background="@color/color_recycle_rectangle"
        />
</RelativeLayout>

邏輯代碼 StartExpenseActivity.
ToastUtil 是自定義的彈出視窗，使用系統的替換即可
自定義代碼部分就不貼了，很簡單的幾個個Fragment

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;

    //自定義fragment
    BottomFragmentForIndex index;

    BottomFragmentForApproval approval;

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

        initFragment();//初始化自定義Fragment頁面
        getSupportFragmentManager().beginTransaction().add(R.id.start_activity_framelayout,index).commitNowAllowingStateLoss();
        initBottom();//初始化底部欄
    }

    /**

        a2.selectId = R.mipmap.fragment_install_before;
        a2.text = "測驗3";
        a2.listener = new View.OnClickListener() {

}

以上內容是看過很多大神寫的關于底部導航欄實作的思想，根據個人需求一行一行寫出，
