嘗試使用廣播接收器時遇到一些問題。Android。廣播接收器
目標: 我有三個應用程序,它將工作下一個架構 1.首先 - 廣播接收器應用程序,它會寫一些數據時,它會收到一條消息數據庫。 2.第二 - 是應用程序的Android的將發送一些意圖必須保存在數據庫中的數據。 3.第三 - 在主屏幕上的小部件,它也會發送一些意圖,必須保存在數據庫中的數據。
因此,我在日食上製作了三個應用程序。 1. BroadcastReceiverExample - 廣播接收機,它有下一個文件
package com.test.receive;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;
public class SimpleReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "service get started action", Toast.LENGTH_LONG).show();
Log.e("START","START");
}
}
和清單文件源
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.test"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="7" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
<receiver android:enabled="true" android:name=".receive.SimpleReceiver" android:exported="false">
<intent-filter android:priority="999">
<action android:name="com.test.SIMPLE_TEST_SERVICE"></action>
</intent-filter>
</receiver>
</application>
</manifest>
也是我在Eclipse 創建應用項目(BroadcastSenderExample),並將其與下一發送代碼
文件package com.test.sender;
import com.test.R;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class BroadcastSenderExample extends Activity {
public final static String ACTION="com.test.SIMPLE_TEST_SERVICE";
public final static String TYPE="type";
public final static int START=1;
public final static int STOP=0;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnStart=(Button)findViewById(R.id.btnStart);
btnStart.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent bcIntent=new Intent(ACTION);
sendBroadcast(bcIntent);
}
});
btnEnd=(Button)findViewById(R.id.btnEnd);
btnEnd.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent bcIntent=new Intent(ACTION);
sendBroadcast(bcIntent);
}
});
}
private Button btnStart=null;
private Button btnEnd=null;
}
然後我在設備上安裝第一個應用程序(並且模擬器也嘗試),然後安裝第二個應用程序。 然後第二個應用程序運行意圖調用什麼都沒有發生。
我在做什麼錯?
我就與下一個代碼
項目一個wBRReceiver
文件WBRReceiver.java
包com.x.brreceiver兩個項目;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;
public class WBRReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context arg0, Intent arg1) {
Log.i("THIS IS A TEST RECEIVER","THIS IS A TEST RECEIVER");
Toast.makeText(arg0, "this is a test receiver", Toast.LENGTH_LONG).show();
}
}
AndroidManifest.xml中
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.x.brreceiver"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
<receiver android:name="WBRReceiver">
<intent-filter>
<action android:name="com.x.START"></action>
</intent-filter>
</receiver>
</application>
</manifest>
而且項目中的兩個wBRSender
文件WBRSenderActivity.java
package com.x.brsender;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class WBRSenderActivity extends Activity {
private String ACTION_NAME="com.x.START";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent brr=new Intent(ACTION_NAME);
//I can't use this
//brr.setClass(this, WBRReceiver.class);
//Because i just don't have this class in this case
sendBroadcast(brr);
}
}
和明顯
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.x.brsender"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".WBRSenderActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
然後我安裝的第一個應用到模擬器,然後運行第二個應用程序。它的工作原理。
