Android 与Unity交互之Toast消息

Toast.makeText(MainActivity.this,message.obj.toString(),Toast.LENGTH_SHORT).show();这一句代码不能直接放在

public void ShowMessage(String msg){    Log.e("-------", msg);    // And this is how you call it from the worker thread:

　　Toast.makeText(MainActivity.this,message.obj.toString(),Toast.LENGTH_SHORT).show();

}来接收Unity发送过来的消息。具体是这样的，在继承UnityPlayerActivity或UnityNativePlayerActivity的Activity中：在onCreate中加入下列代码：

（需要import android.os.Message;）

//处理事件mHandler = new Handler(Looper.getMainLooper()) {    @Override    public void handleMessage(Message message) {        // This is where you do your work in the UI thread.        // Your worker tells you in the message what to do.        if(message.what == 1111){            Toast.makeText(MainActivity.this,message.obj.toString(),Toast.LENGTH_SHORT).show();        }    }};

然后在类体中加入

public void ShowMessage(String msg){    Log.e("-------", msg);    // And this is how you call it from the worker thread:    Message message = mHandler.obtainMessage( 1111,msg);    message.sendToTarget();}
