============问题描述============

1.将Unity中的项目导出成Android项目，再放入到Eclipse中，然后新建一个Android项目，以Unity那个项目为类库。
2.然后我开始写一个xml布局，布局中间是一个LinearLayout，上下分别是Button。LinearLayout用来放Unity里的内容。
现在遇到的问题是如果再Unity画面加载完成之前，按钮的点击事件是可以执行的。当Unity加载完成以后，按钮就失效了。根本点不了。是因为Unity盖住了整个屏幕还是占据了整个焦点？现在不知道是应该在Unity代码里面改还是在Android里面改，有大神知道么？
下面附上代码：

package com.t.t;import com.unity3d.player.UnityPlayer;import com.unity3d.player.UnityPlayerNativeActivity;import android.os.Bundle;import android.view.View;import android.widget.Button;import android.widget.LinearLayout;import android.widget.Toast;public class MainActivity extends UnityPlayerNativeActivity{private LinearLayout unity;private Button round,right,left;private String Tag="Unity3D";@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);//设置布局文件setContentView(R.layout.test);//mUnityPlayer为一个全局的引用变量，而且已 经在父类中设置好了，所以直接拿来用就可以了View playerView = mUnityPlayer.getView();//将Unity的视图添加到我们为其准备的父容器中unity = (LinearLayout) findViewById(R.id.unity);playerView.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubToast.makeText(MainActivity.this, "222222", Toast.LENGTH_LONG).show();}});unity.addView(playerView);round = (Button) findViewById(R.id.trun_round);round.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubUnityPlayer.UnitySendMessage("shouchengchangmaobing", "Answer", "3");}});left = (Button) findViewById(R.id.left);left.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubUnityPlayer.UnitySendMessage("shouchengchangmaobing", "Answer", "1");}});}}

============解决方案1============

Unity盖住了整个屏幕？？？
按钮可见能点击不？
