正好,今天项目中需要,先写了个demo,给大家参考参考、

先上图,需要的自己,看看具体的代码实现步骤

Android 多个listview的实现

大概说一下实现步骤:

1.布局中先用 scrollview 包裹 LinearLayout

  <ScrollView
android:id="@+id/scrollview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/relativeLayout1"
android:fadingEdge="none"
android:scrollbars="vertical"> <LinearLayout
android:id="@+id/linearlayout"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
</LinearLayout>
</ScrollView>

2.具体实现代码

import android.annotation.SuppressLint;
import android.content.Context;
import android.graphics.Color;
import android.os.Bundle;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewGroup.LayoutParams;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.ScrollView;
import android.widget.TextView; import java.util.ArrayList;
import java.util.List; public class SearchUserContentActivity extends BaseActivity { @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search_user_content); initView(); addUserListview(); addContentListview();
}
ScrollView scrollView;
LinearLayout all;
private void initView() {
LayoutInflater inflater = LayoutInflater.from(this);
//LinearLayout linearLayout = (LinearLayout) inflater.inflate(R.layout.main, null);
//layout_topic = (LinearLayout) linearLayout.findViewById(R.id.linearlayout);
all = (LinearLayout) findViewById(R.id.linearlayout);
scrollView = (ScrollView) findViewById(R.id.scrollview);
} private void addUserListview( ){
TextView textView = new TextView(this);
textView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
textView.setText("第一个ListView");
textView.setGravity(Gravity.CENTER);
textView.setTextSize(18);
textView.setTextColor(Color.BLACK);
all.addView(textView); ArrayList arraylist = new ArrayList(); // 生成动态数组
for (int i = 1; i <= 10; i ++) {
arraylist.add( "第一个测试" + i );
} ListViewAdapter listViewAdapter = new ListViewAdapter(this, arraylist);
ListView listView = new ListView(this);
int height = arraylist.size() * 50;
listView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, height));
listView.setDividerHeight(1); listView.setAdapter(listViewAdapter);
all.addView(listView);
} private void addContentListview( ){
TextView textView = new TextView(this);
textView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
textView.setText("第二个ListView");
textView.setGravity(Gravity.CENTER);;
textView.setTextSize(18);
textView.setTextColor(Color.BLACK);
all.addView(textView); ArrayList arraylist = new ArrayList(); // 生成动态数组
for (int i = 11; i <= 20; i ++) {
arraylist.add( "第二个测试" + i );
}
ListViewAdapter listViewAdapter = new ListViewAdapter(this, arraylist); ListView listView = new ListView(this);
int height = arraylist.size() * 50;
listView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, height));
listView.setDividerHeight(1); listView.setAdapter(listViewAdapter);
all.addView(listView);
} class ListViewAdapter extends android.widget.BaseAdapter {
Context context;
List<String> datas; public ListViewAdapter(Context _context,
List<String> relativesList) {
this.datas = relativesList;
this.context = _context;
} @Override
public int getCount() {
return datas.size();
} @Override
public Object getItem(int position) {
return position;
} @Override
public long getItemId(int position) {
return position;
}
public final class ViewHolder {
public TextView name;//昵称
}
@SuppressLint("InflateParams")
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if(convertView == null) {
holder = new ViewHolder();
convertView = LayoutInflater.from(context).inflate(R.layout.item_discovery_search_user, null);
holder.name = (TextView) convertView.findViewById(R.id.name);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.name.setText(datas.get(position));
return convertView;
} }
}
