Android 设置动态listview项的高度

我是Android开发新手，在设计方面遇到了麻烦。我正在尝试制作一个短信应用程序。我成功地访问了收件箱并显示了联系人姓名。现在，我想在每个

列表视图项上设置一个自定义高度，并删除看起来像底部边框的分隔线高度。
android:minHeight
在我的情况下似乎不起作用。我还想在每个动态创建的
listview项上添加click事件，但它似乎不起作用

这是我的密码：

MainActivity.java

public class MainActivity extends ListActivity {

    ArrayList<String> messages = new ArrayList<String>();

    ArrayAdapter<String> adapter;
    ArrayList<String> msglist = new ArrayList<String>();
    String num;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ListView lvmsgs = (ListView) findViewById(R.id.msglist);
        Uri uriSMSURI = Uri.parse("content://sms/inbox");
        Cursor cur = getContentResolver().query(uriSMSURI, null, null, null, null);
        String sms = null;
        ContentResolver resolver = null;
        while (cur.moveToNext()) {
            sms += "From :" + cur.getString(2) + " : " + cur.getString(cur.getColumnIndexOrThrow("body")) + "\n";
            num = cur.getString(2);
            num = num.replace("+639", "09");
            if (msglist.contains(num)) {

            } else {
                msglist.add(num);
                messages.add(getContactName(num).toString());
            }
        }
        adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, messages);
        setListAdapter(adapter);
        lvmsgs.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Toast.makeText(getApplicationContext(), "Toast",
                        Toast.LENGTH_LONG).show();
            }
        });
    }

    private String getContactName(String number) {

        String name = null;
        String[] projection = new String[]{ContactsContract.PhoneLookup.DISPLAY_NAME};
        Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
        Cursor cursor = getContentResolver().query(contactUri, projection, null, null, null);

        if (cursor.moveToFirst()) {
            name = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
        } else {
            return number;
        }
        return name;
    }
}

public类MainActivity扩展了ListActivity{
ArrayList消息=新建ArrayList（）；
阵列适配器；
ArrayList msglist=新的ArrayList（）；
字符串数；
@凌驾
创建时受保护的void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；

if（msglist.contains（num））{
}否则{
msglist.add（num）；
messages.add（getContactName（num.toString（））；
}
}
adapter=new ArrayAdapter（这是android.R.layout.simple\u list\u item\u 1，消息）；
setListAdapter（适配器）；
lvmsgs.setOnItemClickListener（新的AdapterView.OnItemClickListener（）{
@凌驾
public void onItemClick（AdapterView父对象、视图、整型位置、长id）{
Toast.makeText（getApplicationContext（），“Toast”，
Toast.LENGTH_LONG）.show（）；
}
});
}
私有字符串getContactName（字符串编号）{
字符串名称=null；
字符串[]投影=新字符串[]{ContactsContract.PhoneLookup.DISPLAY_NAME}；
Uri contactUri=Uri.withAppendedPath（ContactsContract.PhoneLookup.CONTENT\u FILTER\u Uri，Uri.encode（number））；
Cursor Cursor=getContentResolver（）.query（contactUri，projection，null，null，null）；
if（cursor.moveToFirst（））{
name=cursor.getString（cursor.getColumnIndex（ContactsContract.PhoneLookup.DISPLAY_name））；
}否则{
返回号码；
}
返回名称；
}
}

活动\u main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="#ffffff"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity">

    <ListView
        android:id="@+id/msglist"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true"
        android:descendantFocusability="blocksDescendants"
        android:focusable="false"
        android:focusableInTouchMode="false" />
</RelativeLayout>

我认为您可以将自己的布局传递给arrayadapter。创建一个只有文本视图而没有任何布局的布局。并将高度和填充设置为文本视图

activity_main:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity">

<ListView
    android:id="@+id/lvCustomList"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</RelativeLayout>

layout_list_item.xml

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_vertical"
    android:orientation="horizontal"
    android:padding="10dp">
    <ImageView
    android:id="@+id/ivIcon"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/start1" />
   <LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical">
    <TextView
        android:id="@+id/tvTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="5dp"
        android:text="Title" />
    <TextView
        android:id="@+id/tvDesc"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="5dp"
        android:text="Description" />
</LinearLayout>
</LinearLayout>

ModelClass:

package com.example.evuser.customlistviewdemo;

public class ListData {

String Description;
String title;
int imgResId;

public String getDescription() {
    return Description;
}

public void setDescription(String description) {
    Description = description;
}

public String getTitle() {
    return title;
}

public void setTitle(String title) {
    this.title = title;
}

public int getImgResId() {
    return imgResId;
}

public void setImgResId(int imgResId) {
    this.imgResId = imgResId;
}

导入java.util.ArrayList

public class MyBaseAdapter extends BaseAdapter {

ArrayList<ListData> myList = new ArrayList<ListData>();
LayoutInflater inflater;
Context context;


public MyBaseAdapter(Context context, ArrayList<ListData> myList) {
    this.myList = myList;
    this.context = context;
    inflater = LayoutInflater.from(this.context);
}

@Override
public int getCount() {
    return myList.size();
}

@Override
public ListData getItem(int position) {
    return myList.get(position);
}

@Override
public long getItemId(int position) {
    return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    MyViewHolder mViewHolder;

    if (convertView == null) {
        convertView = inflater.inflate(R.layout.layout_list_item, parent, false);
        mViewHolder = new MyViewHolder(convertView);
        convertView.setTag(mViewHolder);
    } else {
        mViewHolder = (MyViewHolder) convertView.getTag();
    }

    ListData currentListData = getItem(position);

    mViewHolder.tvTitle.setText(currentListData.getTitle());
    mViewHolder.tvDesc.setText(currentListData.getDescription());
    mViewHolder.ivIcon.setImageResource(currentListData.getImgResId());

    return convertView;
}

private class MyViewHolder {
    TextView tvTitle, tvDesc;
    ImageView ivIcon;

    public MyViewHolder(View item) {
        tvTitle = (TextView) item.findViewById(R.id.tvTitle);
        tvDesc = (TextView) item.findViewById(R.id.tvDesc);
        ivIcon = (ImageView) item.findViewById(R.id.ivIcon);
    }
}

要设置行项目的高度，您应该为行创建自定义布局，并将其作为第二个参数传递给
ArrayAdapter
，而不是使用默认的
android.R.layout.simple_list_item_1
@ρƏσѕρєK您能给我一个示例代码吗？对不起，我是新手。我如何创建自己的布局？创建新的xml？对不起，我对此一无所知。是的，在布局文件夹中创建一个新的xml。并将此文件的所有xml代码通过。
AdapterClass:

package com.example.evuser.customlistviewdemo;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

public class MyBaseAdapter extends BaseAdapter {

ArrayList<ListData> myList = new ArrayList<ListData>();
LayoutInflater inflater;
Context context;


public MyBaseAdapter(Context context, ArrayList<ListData> myList) {
    this.myList = myList;
    this.context = context;
    inflater = LayoutInflater.from(this.context);
}

@Override
public int getCount() {
    return myList.size();
}

@Override
public ListData getItem(int position) {
    return myList.get(position);
}

@Override
public long getItemId(int position) {
    return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    MyViewHolder mViewHolder;

    if (convertView == null) {
        convertView = inflater.inflate(R.layout.layout_list_item, parent, false);
        mViewHolder = new MyViewHolder(convertView);
        convertView.setTag(mViewHolder);
    } else {
        mViewHolder = (MyViewHolder) convertView.getTag();
    }

    ListData currentListData = getItem(position);

    mViewHolder.tvTitle.setText(currentListData.getTitle());
    mViewHolder.tvDesc.setText(currentListData.getDescription());
    mViewHolder.ivIcon.setImageResource(currentListData.getImgResId());

    return convertView;
}

private class MyViewHolder {
    TextView tvTitle, tvDesc;
    ImageView ivIcon;

    public MyViewHolder(View item) {
        tvTitle = (TextView) item.findViewById(R.id.tvTitle);
        tvDesc = (TextView) item.findViewById(R.id.tvDesc);
        ivIcon = (ImageView) item.findViewById(R.id.ivIcon);
    }
}

 In the above example, I have given how to create custom layout for listview and use that in adapter class. You modify this class according to your requirement.
