将 Imageview 设置为全屏 Activity
Set Imageview To Full Screen of Activity
我有一个线性布局，它有两个图像视图，第一个设置为显示正常图像，另一个设置为当任何用户触摸第一个图像视图时隐藏，第二个图像视图可见并设置为全屏..但在此期间我我发给你的错误...
我有 followed this code

propertyImage 是我的第一张图片，它显示我的图片，但是当我触摸它时，它会转到 zoomImagefromphoto class

findViewById(R.id.liimage).getGlobalVisibleRect(finalBounds, globalOffset);
如何解决？帮助我的朋友提前谢谢。
除了这种方法，您还可以这样做，当单击图像时添加一个 Fragment/Activity 全屏显示您的图像。
而不是 zoomImageFromPhoto(final View thumbView, ImageView property_image2)
使用 zoomImageFromPhoto(final View thumbView, int property_image2)
之后不要忘记做
expandedImageView.setImageResource(property_image2);
应该进行的更改如下...希望这会有所帮助

版面设计请找，

并为 'img_small_icon' 小图标添加点击监听器。
例如：
ImageView imgSmall,imgLarge;
imgSmall = (ImageView) findViewById(R.id.img_small_icon);
imgLarge = (ImageView) findViewById(R.id.img_large_icon);
imgSmall.setOnClickListener(new OnClickListener() {
@Override

// TODO Auto-generated method stub
if(imgLarge.getVisibility() == View.INVISIBLE){
//Here you can add the Fade In/Out animation start
imgLarge.setVisibility(View.VISIBLE);
}
}
});

android:fillAfter="true">
<alpha
android:duration="500"

android:toAlpha="5.0"/>
</set>
将此文件保存在 drawable fodler 中。
在您的 onClickListener 中
Animation fadeOutAnimation = AnimationUtils.loadAnimation(mContext, R.anim.fade_out);
imgLarge.startAnimation(fadeOutAnimation);
没有必要做这么冗长的过程..做你需要一个 xml class
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/img_large_icon"
android:layout_width="match_parent"
android:layout_height="match_parent" />
然后将该图像转换为字节数组
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byteArray = stream.toByteArray();
当点击图片时使用 intent 发送这个字节数组
intent.putExtra("Image", byteArray);
制作另一个activity
会转到下一个activity
写这段代码
public class Image_fullscreen_activity extends Activity {
private Bitmap bmp;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.fullscreen_image);
byte[] byteArray = getIntent().getByteArrayExtra("Image");
Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
ImageView iv=(ImageView)findViewById(R.id.img_large_icon);
iv.setImageBitmap(bmp);
}
@Override
public void onBackPressed() {
super.onBackPressed();
}
}
在你的 android 最主要的地方注册这个
<activity
android:name=".Image_fullscreen_activity"
android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"
android:label="@string/app_name" >
</activity>
只管去做你会得到准确的输出
