glide set gif start stop

一张gif图片，控制播放和暂停，用了一个取巧的办法实现的，使用glide和selector.xml文件实现

step1: D:\workspace\MyApplication26\app\build.gradle

 implementation 'com.github.bumptech.glide:glide:4.11.0'
    annotationProcessor 'com.github.bumptech.glide:compiler:4.11.0'

step2:

package com.example.ali.myapplication

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.widget.Button
import android.widget.ImageView
import com.bumptech.glide.Glide

class MainActivity : AppCompatActivity() {
    
    private lateinit var btn_start: Button
    private lateinit var btn_stop: Button
    private lateinit var iv_rc_home: ImageView

    override fun onCreate(savedInstanceState: Bundle?) {
    
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        btn_stop = findViewById(R.id.btn_stop)
        btn_start = findViewById(R.id.btn_start)
        iv_rc_home = findViewById(R.id.iv_rc_home)

        btn_start.setOnClickListener {
    
            Glide.with(this).load(R.drawable.fan_five.gif).into(iv_rc_home);
        }

        btn_stop.setOnClickListener {
    
            Glide.with(this).load(R.drawable.home_select_fan.xml).into(iv_rc_home);
        }
    }
}

step3: home_select_fan.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/fan_five.gif" />
</selector>

step4:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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=".MainActivity">

    <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical">

        <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Hello World!" />

        <Button android:id="@+id/btn_start" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="开始播放" />

        <Button android:id="@+id/btn_stop" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="停止" />

        <ImageView android:id="@+id/iv_rc_home" android:layout_width="335dp" android:layout_height="252dp" android:src="@mipmap/ic_launcher" />


    </LinearLayout>


</androidx.constraintlayout.widget.ConstraintLayout>
