全屏背景半透明对话框用PhotoView显示图片放大缩小图片

需求：在当前页面悬浮显示图片，背景位透明色。

废话不多说，直接上代码。

 

 

先引入两个库，很常见的啦~~

compile 'com.github.chrisbanes.photoview:library:+'
compile 'com.github.bumptech.glide:glide:3.7.0'

<!--全屏背景半透明 dialog-->
<style name="transparentBgDialog" parent="@android:style/Theme.Dialog">
    <item name="android:windowFrame">@null</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@color/transparent</item>
    <item name="android:backgroundDimEnabled">true</item>
    <item name="android:background">@color/transparent</item>
    <item name="android:windowNoTitle">true</item>
</style>

 

颜色值要透明哦，也可其他色。看产品需求吧，嘻嘻
<color name="transparent">#00000000</color>

 

敲黑板划重点啦！！！代码Ctrl +C 吧。哈哈

public class ShowImagesDialog extends Dialog {

    private View mView;
    private Activity mContext;
    private PhotoView photoView;
    private String imgUrls;

    public ShowImagesDialog(@NonNull Activity context, String imgUrls) {
        super(context, R.style.transparentBgDialog);
        this.mContext = context;
        this.imgUrls = imgUrls;


        initView();
        initData();
    }

    private void initView() {
        photoView = new uk.co.senab.photoview.PhotoView(mContext);

    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(photoView);
        Window window = getWindow();
        WindowManager.LayoutParams wl = window.getAttributes();
        wl.x = 0;
        wl.y = 0;

        DisplayMetrics metrics = new DisplayMetrics();
        mContext.getWindowManager().getDefaultDisplay().getMetrics(metrics);
        wl.height = metrics.heightPixels;
        wl.width = metrics.widthPixels;
        wl.gravity = Gravity.CENTER;
        window.setAttributes(wl);
    }

    private void initData() {
        //点击图片监听

        Glide.with(mContext)
                .load(imgUrls)
                .placeholder(R.mipmap.ic_launcher)
                .error(R.mipmap.ic_launcher)
                .into(new SimpleTarget<GlideDrawable>() {
                    @Override
                    public void onResourceReady(GlideDrawable resource, GlideAnimation<? super GlideDrawable> glideAnimation) {
                        photoView.setImageDrawable(resource);
                    }
                });

    }
}

 

看效果：惊艳吧。哈哈
