如何通过Android的java代码调整ImageView的大小

当我按下图像时，如何通过java代码调整ImageView的大小

这是我的xml

<ImageView
            android:id="@+id/MyPic"
            android:src="@drawable/clean"
            android:layout_gravity="center"
            android:gravity="center"
            android:layout_height="70dp"
            android:layout_width="90dp"
            android:adjustViewBounds="true"
            android:scaleType="fitXY"
             />

您可以调整图像大小，如下所示

MyPic = (ImageView) findViewById(R.id.MyPic);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(50, 50);
MyPic .setLayoutParams(layoutParams);

具体点。是否要缩放图像视图的动画？或者让它立即变大一倍？这次请不要忘记勾选答案。

MyPic = (ImageView) findViewById(R.id.MyPic);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(50, 50);
MyPic .setLayoutParams(layoutParams);
