android根据屏幕高度改变item占ListView高度

首先要知道LayoutParams是什么。利用LayoutParams可以更改每个item在listview中的样子。

// 调整每个Item占屏幕的百分比AbsListView.LayoutParams lp = new AbsListView.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, mPullToRefreshListView.getHeight() / 5);convertView.setLayoutParams(lp);

mPullToRefreshListView为我的listview控件。先获取到该listview在布局中所占的高度。然后除以我想每个页面显示item的个数，就得到了每个item的高度。在用convertView.setLayoutParams(lp);改变当前item在view中的样子。
注意：setLayoutParams必须用父控件的LayoutParams。例如该item的父控件为listview所以使用的是AbsListView。
下面贴上我的适配器的所有代码：
package com.adapter;

import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AbsListView;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;

import com.android_demo.R;
import com.bean.MaoyanBean;

import java.util.List;

import adaptation.AbViewUtil;
import butterknife.BindView;
import butterknife.ButterKnife;

import com.bean.MaoyanBean.DataBean.MoviesBean;
import com.common.SystemApplication;
import com.pullToRefresh.PullToRefreshListView;

public class XlistViewAdapter extends BaseAdapter {
private Activity mActivity;
private LayoutInflater mInflater;
private MaoyanBean mData;
private List list;
private PullToRefreshListView mPullToRefreshListView;

public XlistViewAdapter(Activity mActivity, PullToRefreshListView mPullToRefreshListView, MaoyanBean mData) {    this.mActivity = mActivity;    mInflater = LayoutInflater.from(mActivity);    this.mData = mData;    list = mData.getData().getMovies();    this.mPullToRefreshListView = mPullToRefreshListView;}public int getCount() {    return list.size();}public Object getItem(int position) {    return list.get(position);}public long getItemId(int position) {    return position;}public View getView(int position, View convertView, ViewGroup parent) {    ViewHolder viewHolder = null;    if (convertView == null) {        convertView = mInflater.inflate(R.layout.item_main02, null);        viewHolder = new ViewHolder(convertView);        // 调整每个Item占屏幕的百分比        AbsListView.LayoutParams lp = new AbsListView.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, mPullToRefreshListView.getHeight() / 5);        convertView.setLayoutParams(lp);        convertView.setTag(viewHolder);    } else {        viewHolder = (ViewHolder) convertView.getTag();    }    //图片    SystemApplication.showImage(mActivity, list.get(position).getImg(), viewHolder.iv01);    //影片名    viewHolder.tv01.setText(list.get(position).getNm());    viewHolder.tv02.setText(list.get(position).getScm());    viewHolder.tv03.setText(list.get(position).getShowInfo());    return convertView;}/** * 优化机制 */static class ViewHolder {    @BindView(R.id.iv_01)    ImageView iv01;    @BindView(R.id.tv_01)    TextView tv01;    @BindView(R.id.tv_02)    TextView tv02;    @BindView(R.id.tv_03)    TextView tv03;    ViewHolder(View view) {        ButterKnife.bind(this, view);        AbViewUtil.scaleContentView((LinearLayout) view.findViewById(R.id.rootLayout));    }}
