How to Android? Step3: Get contacts data from android.provider

如何透過Google的android.provider來取得手機通訊錄資料?

1. AndroidManifest.xml : 在此xml檔案加入下列籃色那個安全性設定，不然會一直發生安全性錯誤！

<?xml version="1.0" encoding="utf-8"?> <manifest android="http://schemas.android.com/apk/res/android" package="com.google.test"> <uses-permission android:name="android.permission.READ_CONTACTS" /> <application icon="@drawable/icon"> <activity class=".hello" label="@string/app_name"> <intent-filter> <action value="android.intent.action.MAIN"> <category value="android.intent.category.LAUNCHER"> </category> </action> </intent-filter> </activity> </application></manifest>

2. hello.java : 在Activity java檔中加入下列籃色部份程式碼！

package com.google.test; import android.app.Activity; import android.database.Cursor; import com.google.test.R; import android.os.Bundle; import android.widget.TextView; public class hello extends Activity { private TextView tv; @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); tv =(TextView) findViewById(R.id.test); // An array specifying which columns to return. String[] projection = new String[] { android.provider.BaseColumns._ID, android.provider.Contacts.PeopleColumns.NAME, android.provider.Contacts.PhonesColumns.NUMBER }; // Best way to retrieve a query; returns a managed query. Cursor managedCursor = managedQuery( android.provider.Contacts.Phones.CONTENT_URI, projection, //Which columns to return. null, // WHERE clause--we won't specify. android.provider.Contacts.PeopleColumns.NAME + " ASC"); // Order-by clause. getColumnData(managedCursor); } private void getColumnData(Cursor cur){ String name; String phoneNumber; int nameColumn = cur.getColumnIndex(android.provider.Contacts.PeopleColumns.NAME); int phoneColumn = cur.getColumnIndex(android.provider.Contacts.PhonesColumns.NUMBER); String imagePath; tv.setText(""); while (cur.next()) { name = cur.getString(nameColumn); phoneNumber = cur.getString(phoneColumn); tv.append(name+" : "+phoneNumber+"\n"); } } }

3. main.xml : 在layout資料夾下的main.xml檔案加入下列籃色部份，來顯示抓到的資料！

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