上下文菜单(复制号码、复制号码到短信界面、复制号码到拨号盘功能的实现)

效果图：

代码实现：

1、main.xml

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

2、MainActivity

里面包括了读取通话记录中一些表的URI、以及打电话、发短信的SCHEMA,要是忘了的话，可以在可以查一下

但建议还是到android中去查

package com.njupt.contextmenu1;import android.net.Uri;import android.os.Bundle;import android.provider.CallLog.Calls;import android.app.Activity;import android.content.Context;import android.content.Intent;import android.database.Cursor;import android.graphics.Color;import android.text.ClipboardManager;import android.view.ContextMenu;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.view.ViewGroup;import android.view.ContextMenu.ContextMenuInfo;import android.widget.AdapterView.AdapterContextMenuInfo;import android.widget.CursorAdapter;import android.widget.ListView;import android.widget.TextView;public class MainActivity extends Activity {private static final int MENU_DIAL_ID = 0;private static final int MENU_SMS_ID = 1;private static final int MENU_COPY_ID = 2;private MyAdapter adapter;private ListView listview;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);    listview = (ListView) findViewById(R.id.listview);Cursor c = getContentResolver().query(Calls.CONTENT_URI ,new String[]{Calls._ID,Calls.NUMBER}, null,null, null);adapter = new MyAdapter(this,c);listview.setAdapter(adapter);registerForContextMenu(listview);}    @Override    public void onCreateContextMenu(ContextMenu menu, View v,    ContextMenuInfo menuInfo) {    menu.add(0,MENU_DIAL_ID,0,"复制号码到拨号盘");    menu.add(0,MENU_SMS_ID,0,"发送短信");    menu.add(0,MENU_COPY_ID,0,"复制号码");        super.onCreateContextMenu(menu, v, menuInfo);    }        @Override    public boolean onContextItemSelected(MenuItem item) {    AdapterContextMenuInfo acmi =  (AdapterContextMenuInfo) item.getMenuInfo();    int position = acmi.position;    Cursor cursor = (Cursor) adapter.getItem(position);    String number = cursor.getString(cursor.getColumnIndex(Calls.NUMBER));    int id = item.getItemId();             Intent intent = null;    switch (id) {case MENU_DIAL_ID:intent = new Intent();intent.setAction(Intent.ACTION_DIAL);intent.setData(Uri.parse("tel:" + number));startActivity(intent);break;case MENU_SMS_ID:intent = new Intent();intent.setAction(Intent.ACTION_SENDTO);intent.setData(Uri.parse("smsto:" + number));startActivity(intent);break;case MENU_COPY_ID:ClipboardManager cm = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);cm.setText(number);default:break;}        return super.onContextItemSelected(item);    }        private class MyAdapter extends CursorAdapter{    public MyAdapter(Context context , Cursor cursor) {    super(context, cursor);}        @Override    public View newView(Context context, Cursor cursor, ViewGroup parent) {        TextView tv = new TextView(context);    tv.setTextSize(22);    tv.setTextColor(Color.GREEN);    return tv;    }            @Override    public void bindView(View view, Context context, Cursor cursor) {        String number = cursor.getString(cursor.getColumnIndex(Calls.NUMBER));    TextView tv = (TextView) view;    tv.setText(number);    }    }@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}}

3、AndroidManifest.xml

<uses-permission android:name="android.permission.READ_CONTACTS"/>
