我有2个Android应用程序。两者都安装在手机上。比方说两个包的名称是com.android.test1和com.android.test2。我怎样才能调用该方法 Main2method（）从test1.Main类？

有关测试1级：

 包com.android.test1;
进口android.app.Activity;
进口android.os.Bundle;

公共类主要扩展活动{

    公共无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.main）;
    }
}
 

有关测试2级：

 包com.android.test2;
进口android.app.Activity;
进口android.os.Bundle;

公共类MAIN2延伸活动{

    公共无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.main）;
    }

    公共静态无效Main2method（）{
        //做一点事..
    }
}
 

解决方案

也许你可以播放一个Intent调用它。

 意图是=新的意向书（com.android.test2.Main2method）;
context.sendBroadcast（IT）
 

请在com.android.test1.Main2一个BroadcastReceiver接收广播：

 公共类ActionReceiver扩展的BroadcastReceiver {
    @覆盖
    公共无效的onReceive（上下文的背景下，意图意图）{
        如果（com.android.test2.Main2method.equalsIgnoreCase（intent.getAction（）））{
            Main2method（）;
        }
    }
}
 

在类MAIN1的onCreate方法注册接收器：

 公共无效的onCreate（包savedInstanceState）{
    super.onCreate（savedInstanceState）;
    ...

    接收器=新ActionReceiver（）;
    IntentFilter的过滤器=新的IntentFilter（）;
    filter.addAction（com.android.test2.Main2method）;
    registerReceiver（接收机，过滤器）;
    ...
}
 

I have 2 android apps. Both are installed on the phone. Lets say the package name for the two are com.android.test1 and com.android.test2. How can i call the method Main2method() from the test1.Main class ?

Class for test1:

package com.android.test1;
import android.app.Activity;
import android.os.Bundle;

public class Main extends Activity {  

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}

Class for test2:

package com.android.test2;
import android.app.Activity;
import android.os.Bundle;

public class Main2 extends Activity {  

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    public static void Main2method() {
        //do something..
    }
}

Maybe you can broadcast an Intent to call it.

Intent it = new Intent("com.android.test2.Main2method");
context.sendBroadcast(it)

make a BroadcastReceiver in com.android.test1.Main2 to receive the broadcast:

public class ActionReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if ("com.android.test2.Main2method".equalsIgnoreCase(intent.getAction())) {
            Main2method();
        } 
    }
}

register the receiver in onCreate method of class Main1:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...

    receiver = new ActionReceiver();
    IntentFilter filter = new IntentFilter();
    filter.addAction("com.android.test2.Main2method");
    registerReceiver(receiver, filter);
    ...
}
