android - 如何在 Android 中以编程方式创建联系人组？

Question

我想创建一个联系人组，给它一个特定的名称，然后向其中添加联系人。

我可以使用 RawContacts 类建立联系，但我不知道如何

1. 创建联系人组
2. 然后将联系人添加到该特定组。

有人可以帮我提供一些示例代码吗？

请使用此代码。它会对某些人有所帮助。

ListView 控件的另外两个类。

package com.example.new_group_and_add_contacts;

import java.util.List;
import android.app.Activity;
import android.graphics.Bitmap;
import android.media.ThumbnailUtils;
import android.provider.MediaStore;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.ImageView;
import android.widget.TextView;

public class InteractiveArrayAdapter extends ArrayAdapter<Model> {

public static List<Model> list = null;
private final Activity context; 


public InteractiveArrayAdapter(Activity context, List<Model> list) {
    super(context, R.layout.rowbuttonlayout, list);
    this.context = context;
    this.list = list;
}

static class ViewHolder {
    protected TextView text;
    protected CheckBox checkbox;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View view = null;


    if (convertView == null) {
        LayoutInflater inflator = context.getLayoutInflater();
        view = inflator.inflate(R.layout.rowbuttonlayout, null);
        final ViewHolder viewHolder = new ViewHolder();
        viewHolder.text = (TextView) view.findViewById(R.id.label);     
        viewHolder.text.setText("Select Ringtone");         


        viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check);         
        viewHolder.checkbox
                .setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                    @Override
                    public void onCheckedChanged(CompoundButton buttonView,
                            boolean isChecked) {
                        Model element = (Model) viewHolder.checkbox
                                .getTag();
                        element.setSelected(buttonView.isChecked());                            
                    }
                });


        view.setTag(viewHolder);
        viewHolder.checkbox.setTag(list.get(position));
    } else {
        view = convertView;
        ((ViewHolder) view.getTag()).checkbox.setTag(list.get(position));
    }


    ViewHolder holder = (ViewHolder) view.getTag();
    holder.text.setText(list.get(position).getName());

    holder.checkbox.setChecked(list.get(position).isSelected());


    return view;
    }
} 

和

package com.example.new_group_and_add_contacts;

public class Model {

private String name;
private boolean selected;

public Model(String name) {
    this.name = name;
    selected = false;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public boolean isSelected() {
    return selected;
}

public void setSelected(boolean selected) {
    this.selected = selected;
}

} 

而 XML 文件是， 这个xml文件名为main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" 
android:id="@+id/layoutexample"
android:background="#000000"
>

<EditText
    android:id="@+id/textview"
    android:layout_width="200dp"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:hint="Enter Group Name"
    android:textColor="#000000"
    android:layout_marginLeft="10dp"
    android:layout_marginRight="10dp"
    android:layout_marginTop="10dp"
    />


<ListView
    android:id="@+id/mylist"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:layout_weight="1"
    android:background="#552244"
    android:cacheColorHint="#00000000"
    android:layout_margin="10dp"
    >
</ListView>

<Button 
     android:id="@+id/mybutton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:text="Create New Group"
    android:onClick="onClick"
    android:layout_gravity="center_horizontal"
    android:textColor="#000000"
    />



</LinearLayout>

ListView 的另一个 XML 文件，名称为 rowbuttonlayout.xml。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" 
android:orientation="horizontal"
>

<CheckBox
    android:id="@+id/check"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
</CheckBox>



<TextView
    android:id="@+id/label"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello"
    android:textSize="15dp"
    android:textColor="#FF0000"         
    >
</TextView>

</LinearLayout> 

此代码适用于Andoid2.2以上的手机。
