如何让ImageView高度和宽度保持一致？

问题描述

<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/image"/>

解决方案

int squareDim = 1000000000;
@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec){

super.onMeasure(widthMeasureSpec, heightMeasureSpec);
int h = this.getMeasuredHeight();
int w = this.getMeasuredWidth();
int curSquareDim = Math.min(w,h);
if(curSquareDim < squareDim)
{
squareDim = curSquareDim;
}
Log.d("MyApp", "h "+h+"w "+w+"squareDim "+squareDim);
setMeasuredDimension(squareDim, squareDim);
}
