android GIF drawable和PhotoView图片缩放

1、添加依赖

  project：maven { url "https://jitpack.io" }//第三方


 app：   implementation 'pl.droidsonroids.gif:android-gif-drawable:1.1.17'

2、编写XML

 <pl.droidsonroids.gif.GifImageButton
        android:id="@+id/gifImageButton"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />
        <!--android:src="@mipmap/timg"-->

3、Activity使用

package com.example.administrator.baserecyclerviewadapterhelper.duo;

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.MediaController;

import com.example.administrator.baserecyclerviewadapterhelper.R;

import pl.droidsonroids.gif.GifDrawable;
import pl.droidsonroids.gif.GifImageButton;

public class GifActivity extends AppCompatActivity implements View.OnClickListener {
    private GifImageButton gifImageButton;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.gif_main);
        initView();
        gifImageButton = (GifImageButton) findViewById(R.id.gifImageButton);
        gifImageButton.setImageResource(R.drawable.timg);
        final MediaController mc = new MediaController(this);
        mc.setMediaPlayer((GifDrawable) gifImageButton.getDrawable());
        mc.setAnchorView(gifImageButton);
        gifImageButton.setOnClickListener(
                new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                       mc.show();//显示进度条
                    }
                }
        );
    }

    private void initView() {
        gifImageButton = (GifImageButton) findViewById(R.id.gifImageButton);
        gifImageButton.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            default:
                break;
            case R.id.gifImageButton:

                break;
        }
    }
}

二、PhotoView
1、添加依赖

//图片缩放
    implementation 'com.github.chrisbanes:PhotoView:2.0.0'

2、XML使用

<com.github.chrisbanes.photoview.PhotoView
        android:id="@+id/imageView2"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/hehe"/>

3、设置图片就可以了

package com.example.administrator.baserecyclerviewadapterhelper;

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;

import com.github.chrisbanes.photoview.PhotoView;

public class PhotoViewActivity extends AppCompatActivity {
    private PhotoView mImageView2;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.photo_name);
        initView();
    }

    private void initView() {
        mImageView2 = (PhotoView) findViewById(R.id.imageView2);
        mImageView2.setImageResource(R.drawable.hehe);
    }
}
