Question

当我旋转屏幕时，ImageView不会重新缩放图像，但原生Imageview会旋转图像。
我怎样才能做到这一点？

项目https://github.com/jasonpolites/gesture-imageview

清单：

<activity android:name="ScaleTypeCenterInsidePortrait"
                  android:configChanges="orientation|screenSize"></activity>

我的ScaleTypeCenterInsidePortrait类：

public class ScaleTypeCenterInsidePortrait extends ExampleActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.scale_type_inside_portrait);
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
    }

}

Answer 1

在代码中替换这些行

public class ScaleTypeCenterInsidePortrait extends ExampleActivity {

ImageView imv;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
imv=new ImageView(this);
imv.setimageResource(R.drawable."your image name in the drwable folder");
imv.setscaleType(ScaleType.Center_Inside);

    }
@Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        if(newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE){
            setContentView(imv);
        }
        else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
            setContentView(imv);         
        }
    }

} 并让你显示这些行

<activity android:name=".Activity_name"
          android:configChanges="orientation|keyboardHidden">

如何在方向更改后缩放ImageView？
