滑鼠點擊時間,跳到設定畫面
點擊按鈕,時間變綠色
重點XML,不要設CONFIGURE(這裡是要使用者點擊appwidget來設定),xml設錯,不是桌面加不上appwidget,不然就是程式繞半天繞不出來,試很久才試出我想要的
AndroidManifest.xml中指定activity既可(如下)
<activity android:name=".clockConfigure"/>
再來建立Intent指定activity,然後綁定textview,重點就這樣
1.Clock_widget.java,注意紅色部份getActivity,setOnClickPendingIntent來綁定
package test.Clock_widget1;
import java.util.Calendar;
import android.app.PendingIntent;
import android.app.Service;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.os.Handler;
import android.os.IBinder;
import android.os.Message;
import android.util.Log;
import android.widget.RemoteViews;
import android.widget.Toast;
//自定義clock_thread class 繼承Thread,s毫秒送出sendMessage
class clock_Thread extends Thread{
//變數宣告
Handler thandler;
private int sc;
private Message m;
boolean paused;
//建構子,初始化
public clock_Thread(Handler h,int s){
sc=s;//毫秒
thandler =h;
}
public void run(){
super.run();
try{
while(true){
Thread.sleep(sc);
m=new Message();
thandler.sendMessage(m);
}//while
}catch (Exception e) {
Log.d("tag", "error");
// handle exception
}//cttch
}//run
//set handler_
public void set_handler(Handler h){
this.thandler=h;
}
//set second
public void set_second(int s){
this.sc=s;
}
}//thread
public class Clock_widget extends AppWidgetProvider {
//變數宣告
//public Handler c_Handler;
public static Handler w_handler;
private static int[] sappWidgetIds;
private static AppWidgetManager sappWidgetManager;
private static Context scontext;
private clock_Thread cthread;
public static String CLICK_ACTION1 ;
public static String CLICK_ACTION2 ;
public static String CLICK_ACTION3 ;
static private boolean START_TIME;//是否顯示時間
private static final int SHOW_EDITOR = 0;
public static String ACTION_WIDGET_CONFIGURE = "ConfigureWidget";
private PendingIntent refreshPendingIntent;
// 建構子初始化Clock_widget,能初始化盡量初始化
public Clock_widget() {
//按鈕1字串
CLICK_ACTION1 = "test.widget_clock.CLICK1";
//按鈕2字串
CLICK_ACTION2 = "test.widget_clock.CLICK2";
//按鈕2字串
CLICK_ACTION3 = "test.widget_clock.CLICK3";
START_TIME=true;
w_handler=null;
//一開始handler null,1秒送出message
cthread=new clock_Thread(w_handler,1000);
//start thread
cthread.start();
}
@Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
final String action = intent.getAction();
if(action.equals(CLICK_ACTION1)){
//context.startService(intent1);
START_TIME=true;
Toast.makeText(context, "開時時間", Toast.LENGTH_LONG).show();
}
if(action.equals(CLICK_ACTION2)){
START_TIME=false;
Toast.makeText(context, "停止時間", Toast.LENGTH_LONG).show();
}
}
@Override
public void onUpdate(final Context context,AppWidgetManager appWidgetManager, int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
//onUpdate時放到全域變數
sappWidgetManager = appWidgetManager;
sappWidgetIds = appWidgetIds;
scontext = context;
//設定button1狀態
this.self_update_views(scontext,sappWidgetManager,sappWidgetIds,Clock_widget.CLICK_ACTION1,R.layout.main,R.id.button1,Clock_widget.class,false);
//設定button2狀態
this.self_update_views(scontext,sappWidgetManager,sappWidgetIds,Clock_widget.CLICK_ACTION2,R.layout.main,R.id.button2,Clock_widget.class,false);
//設定textview狀態
this.self_update_views(scontext,sappWidgetManager,sappWidgetIds,"ACTION_WIDGET_CONFIGURE",R.layout.main,R.id.textView1,clockConfigure.class,true);
//new handler,啟動service
w_handler =new Handler(){
public void handleMessage(Message msg) {
Intent intent = new Intent(scontext, MyService.class);
//start service
scontext.startService(intent);
}
};//Hamdler
//重設handler
cthread.set_handler(w_handler);
}//onupdate
//因為太多updateAppWidget,寫成method來處理,xid是xml的id,lid是layout中id(ex:button),as是ACTION STRING
private void self_update_views(final Context ct,AppWidgetManager aw, int[] aids,String as,int xid,int lid,Class ac,boolean at){
final Intent refreshIntent = new Intent(ct, ac);
//set action字串
RemoteViews updateViews = new RemoteViews( ct.getPackageName(), xid);
refreshIntent.setAction(as);
if(at){
//因為要切換到Activity,PendingIntent呼叫getActivity,這裡是重點!!
refreshPendingIntent = PendingIntent.getActivity(ct, 0,refreshIntent, PendingIntent.FLAG_UPDATE_CURRENT);
}else{
// 因為要Broadcast廣播,PendingIntent呼叫getBroadcast
refreshPendingIntent = PendingIntent.getBroadcast(ct, 0,refreshIntent, PendingIntent.FLAG_UPDATE_CURRENT);
}
//final PendingIntent refreshPendingIntent = PendingIntent.getService(cc, 0,refreshIntent, 0);
//設定button當使用者點擊button,然後onReceive接收作判斷,或綁定textview1,當使用者點擊textview啟動activity來改變appwidget
updateViews.setOnClickPendingIntent(lid, refreshPendingIntent);
//update view
aw.updateAppWidget(aids, updateViews);
}
//取得時間,宣告成static可值接用,不須new
public static String get_date(){
int c_Minutes; //分
int c_Hour; //時
int c_Second;
int c_year; //時
int c_month;
final String str;
long time=System.currentTimeMillis();
final Calendar c_Calendar = Calendar.getInstance();
c_Calendar.setTimeInMillis(time);
c_Hour=c_Calendar.get(Calendar.HOUR);
c_Minutes=c_Calendar.get(Calendar.MINUTE);
c_Second=c_Calendar.get(Calendar.SECOND);
c_month=c_Calendar.get(Calendar.MONTH);
c_year=c_Calendar.get(Calendar.YEAR);
str="西元"+c_year+"年"+c_month+"月"+c_Hour+"時"+c_Minutes+"分"+c_Second+"秒";
return str;
}
//MyService服務程式 ,背景運作
public static class MyService extends Service {
//onStart階段service啓動只執行一次
@Override
public void onStart(Intent intent, int startId) {
if(START_TIME){
ComponentName thisWidget = new ComponentName(this, Clock_widget.class);
AppWidgetManager manager = AppWidgetManager.getInstance(this);
RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.main);
//Toast.makeText(this, "開時時間", Toast.LENGTH_LONG).show();
//remoteViews.setTextColor(R.id.textView1, -1);
remoteViews.setTextViewText(R.id.textView1, get_date());
manager.updateAppWidget(thisWidget, remoteViews);
//Log.d("TAG","true") ;
}else{
//Log.d("TAG","false") ;
}//if
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
} //service
}//app class
2.clockConfigure.java,這裡activity只是作text顏色變換沒甚重點,要注意是clockConfigure.this.finish();讓activity還回appwidget
package test.Clock_widget1;
import android.app.Activity;
import android.appwidget.AppWidgetManager;
import android.content.ComponentName;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.widget.RemoteViews;
/**
* @author yplin66
*
*/
/**
* @author yplin66
*
*/
public class clockConfigure extends Activity {
public static String ACTION_WIDGET_CONFIGURE = "ConfigureWidget";
private int mAppWidgetId;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.conf);
}
//botton
public void set_ok(View cv) {
//RemoteViews views = new RemoteViews(clockConfigure.this, R.layout.main);
RemoteViews views = new RemoteViews(getPackageName(), R.layout.main);
ComponentName widget = new ComponentName(clockConfigure.this,Clock_widget.class);
//Updates AppWidget state; gets information about
//installed AppWidget providers and other AppWidget related state.
AppWidgetManager manager = AppWidgetManager.getInstance(clockConfigure.this);
views.setTextColor(R.id.textView1, Color.GREEN);
manager.updateAppWidget(widget, views);
clockConfigure.this.finish();
}//start_clock
}
3.AndroidManifest.xml多一行<activity android:name=".clockConfigure"/>不需要( <action android:name="android.appwidget.action.APPWIDGET_CONFIGURE"/>)
如下
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="test.Clock_widget1"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="11" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
<receiver android:name=".Clock_widget" >
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
<!--receiver註冊action-->
<action android:name="test.widget_clock.CLICK1" />
<action android:name="test.widget_clock.CLICK2" />
</intent-filter>
<meta-data android:name="android.appwidget.provider"
android:resource="@xml/clockprovider" />
</receiver>
<service android:enabled="true" android:name=".Clock_widget$MyService">
<intent-filter>
<!--service註冊action,mark掉>
<action android:name="test.widget_clock.CLICK3" />
</-->
</intent-filter>
</service>
<activity android:name=".clockConfigure"/>
</application>
</manifest>
4.clockprovider.xml(appwidget設定檔xml,並指定initialLayout)
也不需註明conigure來源(android:configure="test.widget_clock.colockConfigure")
<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider
xmlns:android="http://schemas.android.com/apk/res/android"
android:minWidth="100dp"
android:minHeight="50dp"
android:updatePeriodMillis="0"
android:initialLayout="@layout/main"
>
</appwidget-provider>
5.conf.xml 設定appwidget的activity的LAYOUT(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" >
<Button
android:id="@+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="set_ok" android:text="設定綠色"/>
</LinearLayout>
6.main.xml主要viewer(讓appwidget來顯示)
<?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" >
<TextView
android:id="@+id/textView1"
android:layout_width="843dp"
android:layout_height="wrap_content"
android:text="TextView"
android:textSize="18dp" >
</TextView>
<LinearLayout android:id="@+id/linearLayout1" android:layout_height="wrap_content" android:layout_width="match_parent" android:layout_weight="0.13" android:weightSum="1">
<LinearLayout
android:id="@+id/linearLayout2"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="顯示時間"></Button>
<Button android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="暫停時間"></Button>
</LinearLayout>
</LinearLayout>
</LinearLayout>
