Android Studio 通用标题栏

    在开发APP的时候，每个页面的最上方都会出现一个标题栏目，如果每个页面都要去自己搭建一个标题栏，也挺麻烦，当然如果自己感觉自己能做一个好的通用标题栏也不错。但是有现成的插件不用，干嘛还给自己找事情，在说有可能会影响开发周期。所以，今天就介绍一个通用标题栏的插件TitleBar：

   引入TitleBar插件：

plugins {
    id 'com.android.application'
}

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.example.appview"
        minSdkVersion 17
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    repositories {
        flatDir {
            dirs 'libs'

        }
    }

    allprojects {
        repositories {
            maven { url 'https://jitpack.io' }
            maven{ url 'https://maven.aliyun.com/repository/google'}
            maven {
                url 'https://dl.bintray.com/cjt/maven'
            }

        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'com.google.android.material:material:1.2.1'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.1'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation 'com.google.android.gms:play-services-maps:17.0.0'

    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
    implementation 'com.github.getActivity:TitleBar:8.6'

}

新建一个测试类：

package com.example.appview;

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

import com.hjq.bar.OnTitleBarListener;
import com.hjq.bar.TitleBar;

public class Demo extends AppCompatActivity{
  private TitleBar mTitleBar;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_demo);

        //最上方标题栏
        mTitleBar=findViewById(R.id.demo_titlebar);
        mTitleBar.setOnTitleBarListener(new OnTitleBarListener() {

            @Override
            public void onLeftClick(View view) {
               //左侧按钮的监听
            }

            @Override
            public void onTitleClick(View view) {
               //中间标题的监听
            }

            @Override
            public void onRightClick(View view) {
              //右边标题的监听
            }
        });
    }

}

布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
    tools:context=".Demo">
    <com.hjq.bar.TitleBar
        android:id="@+id/demo_titlebar"
        android:background="#1296db"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:rightIcon="@mipmap/preject_item"
        app:leftTitle="返回"
        app:leftColor="@color/white"
        app:titleColor="@color/white"
        app:leftSize="15dp"
        app:leftIcon="@mipmap/fanhui"
        app:title="探测" />

</LinearLayout>

下面的是配置<com.hjq.bar.TitleBar的属性配置，可以根据属性配置任意调节标题栏的样式：

<declare-styleable name="TitleBar">
    <!-- 整体样式 -->
    <attr name="barStyle">
        <enum name="light" value="0x10" />
        <enum name="night" value="0x20" />
        <enum name="transparent" value="0x30" />
        <enum name="ripple" value="0x40" />
    </attr>
    <!-- 中间 -->
    <attr name="title" format="string" />
    <attr name="titleColor" format="color" />
    <attr name="titleSize" format="dimension" />
    <attr name="titleGravity">
        <flag name="left" value="0x03" />
        <flag name="right" value="0x05" />
        <flag name="center" value="0x11" />
        <flag name="start" value="0x00800003" />
        <flag name="end" value="0x00800005" />
    </attr>
    <attr name="titleStyle">
        <flag name="normal" value="0" />
        <flag name="bold" value="1" />
        <flag name="italic" value="2" />
    </attr>
    <!-- 左边 -->
    <attr name="leftTitle" format="string"/>
    <!-- leftIcon 优先于 backButton -->
    <attr name="leftIcon" format="reference" />
    <attr name="leftTint" format="color" />
    <!-- 返回按钮（默认开） -->
    <attr name="backButton" format="boolean" />
    <attr name="leftColor" format="color" />
    <attr name="leftSize" format="dimension" />
    <attr name="leftBackground" format="reference|color" />
    <!-- 右边 -->
    <attr name="rightTitle" format="string" />
    <attr name="rightIcon" format="reference" />
    <attr name="rightTint" format="color" />
    <attr name="rightColor" format="color" />
    <attr name="rightSize" format="dimension" />
    <attr name="rightBackground" format="reference|color" />
    <!-- 分割线 -->
    <attr name="lineVisible" format="boolean" />
    <attr name="lineColor" format="reference|color" />
    <attr name="lineSize" format="dimension" />
    <!-- 图标显示大小 -->
    <attr name="drawableSize" format="dimension" />
    <!-- 图标和文字的间距 -->
    <attr name="android:drawablePadding" />
    <!-- 控件水平内间距 -->
    <attr name="android:paddingVertical" />
    <!-- 控件垂直内间距（可用于调整标题栏自适应的高度） -->
    <attr name="android:paddingHorizontal" />
</declare-styleable>
