Android 中ListView和GridView赋值错位

MyGridView.java

public class MyGridView extends GridView {

public boolean isOnMeasure;

public MyGridView(Context context) {

super(context);

}

public MyGridView(Context context, AttributeSet attrs) {

super(context, attrs);

}

public MyGridView(Context context, AttributeSet attrs, int defStyle) {

super(context, attrs, defStyle);

}

@Override

protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

isOnMeasure = true;

super.onMeasure(widthMeasureSpec, heightMeasureSpec);

}

@Override

protected void onLayout(boolean changed, int l, int t, int r, int b) {

isOnMeasure = false;

super.onLayout(changed, l, t, r, b);

}

}

@Override

public View getView(int position, View convertView, ViewGroup parent) {

System.out.println("xcqw getView 1***position"+position);

ViewHolder holder = null;

if (convertView == null) {

convertView = inflater.inflate(R.layout.item,

parent, false);

holder = new ViewHolder();

holder.tvContent = (TextView) convertView.findViewById(R.id.tv_content);

convertView.setTag(holder);

} else {

holder = (ViewHolder) convertView.getTag();

}

if(((MyGridView) parent).isOnMeasure){

//如果是onMeasure调用的就立即返回

return convertView;

}

System.out.println("xcqw getView 2***position"+position);

String content = contentList.get(position);

holder.tvContent.setText(content);

//如果不是onMeasure调用的就可以正常操作了

//赋值操作

return convertView;

}
