这就是我设置listview行的方法。我想分别在大文本和小文本中使用t1,t2和一个复选框。
这是我的数据源类以及自定义适配器类。
我在getView方法中尝试了很多不能正常工作的东西,我无法理解实际应该去哪里....请有人帮忙吗...我希望我已经描述得很好......如果不,请让我知道......
public class Data{
String t1;
String t2;
Boolean isSelected = false;
public Data(String t1,String t2) {
this.t1 = t1;
this.t2 = t2;
}
public String t1() {
return t1;
}
public String t2() {
return t2;
}
public Boolean getIsSelected() {
return isSelected;
}
}
class CustomAdapter extends BaseAdapter{
Context mContext;
ArrayList<Data> mDataVariable;
public CustomAdapter(Context context, ArrayList<Data> dataVariable) {
this.mContext = context;
this.mDataVariable= dataVariable;
}
@Override
public int getCount() {
return 0;
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
return null;
}
}
这是我尝试弹出列表视图的活动......
public class MyActivity{
ArrayList<Data> mData;
ArrayAdapter<CustomAdapter> mCustomAdapter;
ListView listView;
}
onCreate{
listView= (ListView) findViewById(R.id.ActivityListview);
mData= new ArrayList<mData>();
mData.add(new Data("g1", "its g1"));
mData.add(new Data("g2", "its g2"));
mData.add(new Data("g3", "its g3"));
mData.add(new Data("g4", "its g4"));
mCustomAdapter = new ArrayAdapter<CustomAdapter>(this, R.layout.activity_listview, mData);
listView.setAdapter(mCustomAdapter);
}
我认为我设置得很好,但getView方法是我需要做的所有转换,我现在面临麻烦......
...指导
提前谢谢.....

定义xml文件row_layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/checkbox"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="@+id/checkbox">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/big_text"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/small_text"/>
</LinearLayout>
</RelativeLayout>
并像这样更新您的CustomAdapter
import android.content.Context;
import android.content.res.TypedArray;
import android.provider.ContactsContract;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.CheckBox;
import android.widget.TextView;
import com.newshunt.pracitce.R;
import java.text.DecimalFormat;
import java.util.ArrayList;
import java.util.zip.Inflater;
class CustomAdapter extends BaseAdapter {
Context mContext;
ArrayList<ContactsContract.Data> mDataVariable;
public CustomAdapter(Context context, ArrayList<ContactsContract.Data> dataVariable) {
this.mContext = context;
this.mDataVariable = dataVariable;
}
@Override
public int getCount() {
return 0;
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
RecyclerView.ViewHolder holder;
LayoutInflater inflator = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflator.inflate(R.layout.row_layout, null);
TextView bigText = (TextView) convertView
.findViewById(R.id.big_text);
TextView smallText = (TextView) convertView
.findViewById(R.id.small_text);
CheckBox checkBox = (CheckBox) convertView.findViewById(R.id.checkbox);
return convertView;
}
}
