android – 具有双标签和缩放缩放的无限画廊图像

2019-06-24 23:10:04  阅读：191  来源： 互联网

标签：android image-gallery image-zoom


我有app,它的一个活动是无限的厨房,图像存储在res drawable文件夹中,

我想尝试双重标签和缩放图像,

我搜索谷歌没有任何与无限画廊缩放效果有关的例子,

任何建议将被认真考虑 .

DayGallery.java：

 @SuppressWarnings("deprecation")
public class DayGallery extends Activity {

/** Called when the activity is first created. */

main.xml中

<?xml version="1.0" encoding="utf-8" ?> 
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
   android:layout_width="match_parent" 
   android:layout_height="match_parent" 
   android:orientation="vertical" 
   android:background="#FFDAB9">
 <com.test.demo.InfiniteGallery 
   android:id="@+id/galleryOne" 
   android:layout_width="match_parent" 
   android:layout_height="match_parent" /> 
</LinearLayout>

更新：

根据Yoann Hercouet的回答我替换此代码：

 private ImageView getImageView() { 
  ImageView i = new ImageView(mContext); 
  return i; 
 } 
 }

使用以下代码：

 private GestureImageView getImageView() {   
  GestureImageView i = new GestureImageView(mContext); 
   return i; 
  } 
  }

还调整了getview,所以最后我的课程如下：

 @SuppressWarnings("deprecation")

    /** Called when the activity is first created. */

     tv.setTypeface(FontFactory.getBFantezy(getBaseContext()));
    }

  @SuppressWarnings("deprecation")
  class InfiniteGallery extends Gallery {

public InfiniteGallery(Context context) {

    }

private void init(){
    // These are just to make it look pretty
    setSpacing(25);
    setHorizontalFadingEdgeEnabled(false); 
}
}   
}

如果我使用我原来的main.xmla修改过的类：

<?xml version="1.0" encoding="utf-8" ?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
  android:layout_width="match_parent" 
  android:layout_height="match_parent" 
  android:orientation="vertical" 
  android:background="#FFDAB9">
<com.test.demo.InfiniteGallery
  android:id="@+id/galleryOne" 
  android:layout_width="match_parent" 
  android:layout_height="match_parent" /> 
</LinearLayout>

它使用下面的logcat强制关闭：

如果我使用修改后的main.xml修改后的类,如下所示：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

  android:id="@+id/layout"

   android:layout_height="match_parent" /> 

 <com.polites.android.GestureImageView
   android:id="@+id/image"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent" 
   gesture-image:min-scale="0.75"
  gesture-image:max-scale="10.0"
 />

它还使用以下logcat强制关闭：

更新2

解决方法:

你可以使用自定义imagGallery控件..查看这个https://github.com/kilaka/ImageViewZoom
您可以将图像作为图库视图滑动,并且可以进行缩放缩放.在这个例子中你有一个适配器类..检查出来.
