Question

我需要在[Android]手机启动时启动应用我编译了这段代码，应用程序没有崩溃，但也没有向我显示任何内容！
现在我尝试Toast，但仍然没有找到。有人能帮助我吗？

这是主要活动：

package com.example.simplenotification;

import android.app.Activity;
import android.app.AlarmManager;
import android.app.Notification;
import android.app.NotificationManager; 
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.NotificationCompat;
import android.support.v4.app.NotificationManagerCompat;  
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.RemoteViews;
import android.widget.Toast;

public class MainActivity extends Activity {

 private static final int MY_NOTIFICATION_ID = 0;

 private int mNotificationCount;

 private final CharSequence tickerText ="this is tickerText";
 private final CharSequence contentTitle="this contentTitle";
 private final CharSequence contentText="this coontentText";

 private Intent mNotificationIntent;
 private PendingIntent mContentIntent;

 RemoteViews mContentView = new RemoteViews("com.example.simplenotification.StatusBarWithCustomView", R.layout.custom_view);
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mNotificationIntent = new Intent(getApplicationContext(),AppGet.class);
    mContentIntent = PendingIntent.getActivity(getApplicationContext(), 0, mNotificationIntent, Intent.FLAG_ACTIVITY_NEW_TASK);
    final Button button = (Button) findViewById(R.id.button1);


    button.setOnClickListener(new OnClickListener() {


        public void onClick(View v){


            startNotification();


        }



    });


 }


public void startNotification(){
    Intent notificationIntent = new Intent(getApplicationContext(), MainActivity.class);
    // set intent so it does not start a new activity
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
            Intent.FLAG_ACTIVITY_SINGLE_TOP);
    PendingIntent intent =
            PendingIntent.getActivity(MainActivity.this, 0, notificationIntent, 0);


    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(getApplicationContext())
    .setTicker(tickerText)
    .setSmallIcon(R.drawable.ic_launcher)
    .setAutoCancel(true)
    .setContentTitle("titolo content")
    .setContentText("content text")
    .setContentIntent(intent);


    NotificationManagerCompat mNotificationManager = NotificationManagerCompat.from(getApplicationContext());
    mNotificationManager.notify(MY_NOTIFICATION_ID,notificationBuilder.build());
}
}

这是Manifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.simplenotification"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="14" />


<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
     <receiver android:enabled="true" android:name=".BootUpReceiver"
    android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>
</application>

我不知道如何在模拟器上调试app autorun。我很抱歉

编辑：我在另一个课程中添加了接收器并更改了＆＃39; android名称＆＃39;

    package com.example.simplenotification;

    import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;

public class BootUpReceiver extends BroadcastReceiver {
    @Override
        public void onReceive(Context context, Intent intent) 
    {
        if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
            Intent i = new Intent();
            i.setAction("android.intent.action.MAIN");
            context.startService(i);
            Toast.makeText(context , "saranno 3?" , Toast.LENGTH_SHORT).show();

        }

    }

}

Answer 1

为BootUpReceiver创建一个单独的类。并且在定义接收器

时，android:name中的包名称的清单传递正确路径

 <receiver android:name=".receivers.BootUpReceiver"

更新 - ＆GT;

也可以在你的manisfest中使用此权限

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

Answer 2

不是100％肯定，但请尝试更改此

Toast.makeText(context , "saranno 3?" , Toast.LENGTH_SHORT).show();

进入

Toast.makeText(context.getApplicationContext() , "saranno 3?" , Toast.LENGTH_SHORT).show();

启动完成后自动运行应用程序
