使用Glide在ImageView中显示GIF

Question

我第一次使用Glide在ImageView中显示GIF。我已经按照几个站点的方式对其进行了编码。但它不起作用。我已经给出了以下所有代码：（如果我弄错了什么，请告诉我）

项目级build.gradle

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0'
        classpath 'com.google.gms:google-services:2.1.0-alpha5'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

应用程序级构建。gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.example.winner.myapplication"
        minSdkVersion 19
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        renderscriptTargetApi 19
        renderscriptSupportModeEnabled true

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:22.2.1'
    //compile files('libs/ion-2.1.6.jar')
    //compile files('libs/androidasync-2.1.6.jar')
    compile 'com.github.bumptech.glide:glide:3.7.0'
}

package com.example.winner.myapplication;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

import com.bumptech.glide.Glide;
import com.bumptech.glide.request.target.GlideDrawableImageViewTarget;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final Button submit = (Button) findViewById(R.id.submit);
        submit.setOnClickListener(onClickSubmit);
    }

    View.OnClickListener onClickSubmit = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            ImageView iView = (ImageView) findViewById(R.id.test_image);
            Glide.with(getApplicationContext()).
                    load("http://i.imgur.com/1ALnB2s.gif").into(iView);

        }
    };
}

单击“提交”按钮后，我没有看到GIF图像。

Answer 1

要使用glide加载gif，glide需要几秒钟来处理gif。因此，图像只能在该时间之后加载。所以，虽然你可以使用占位符。

glide.with（this）. load（"http://i.imgur.com/1ALnB2s.gif"）. asGif（）. place eHolder（R.drawable.any_normal_image.png）. into（iView）；

Answer 2

你可以用这个。它对我有用。我希望它也对你有用。

ImageView iView = (ImageView) findViewById(R.id.test_image); 
    GlideDrawableImageViewTarget imageViewPreview = new GlideDrawableImageViewTarget(iView);
    Glide
            .with(this)
            .load(url)
            .listener(new RequestListener<String, GlideDrawable>() {
                @Override
                public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {                       
                    return false;
                }

                @Override
                public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {
                    return false;
                }
            })
            .into(imageViewPreview);
}

它适用于图像和GIF。

Answer 3

正如Glide文档所述，

可以使用.asGif（）强制库加载动画gif，如果未加载，则加载失败：

Glide.with(activity).load(url).asGif().into(view);

我建议你做以下事情

ImageView iView = (ImageView) findViewById(R.id.test_image);
if (iView != null)
    Glide.with(this).load("http://i.imgur.com/1ALnB2s.gif").asGif().into(iView);

有关更多信息，请考虑阅读有关加载Gif的Glide示例https://github.com/bumptech/glide/wiki

提供的代码示例效果良好！
