当我在模拟器上运行我的应用程序时，它运行正常，没有问题发生。但是当我在手机上运行它时，出现的问题“意外停止”。当在手机上运行时，应用程序“意外停止”
在我的申请： 主要活动（背景）可以交换到4个活动：客厅，DiningRoom，Wc，车库。当我尝试去DiningRoom活动时，问题“意外停止”。
这是我的代码：
1.背景
package com.example.background;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import at.abraxas.amarino.Amarino;
public class BackgroundActivity extends Activity {
private Button Wc, Dining_Room, Living_Room, Garage;
private Intent D_intent, L_intent, G_intent, W_intent;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//Amarino.connect(this, DEVICE_ADDRESS);
Living_Room = (Button) findViewById(R.id.living);
//Living_Room.setBackgroundColor(Color.TRANSPARENT);
Living_Room.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
L_intent = new Intent(view.getContext(), LivingRoom.class);
startActivityForResult(L_intent, 0);
}
});
Dining_Room = (Button) findViewById(R.id.dining);
// Dining_Room.setBackgroundColor(Color.TRANSPARENT);
Dining_Room.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
D_intent = new Intent(view.getContext(), DiningRoom.class);
startActivityForResult(D_intent, 0);
}
});
Wc = (Button) findViewById(R.id.wc);
//Wc.setBackgroundColor(Color.TRANSPARENT);
Wc.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
W_intent = new Intent(view.getContext(), Wc.class);
startActivityForResult(W_intent, 0);
}
});
Garage = (Button) findViewById(R.id.garage);
// Garage.setBackgroundColor(Color.TRANSPARENT);
Garage.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
G_intent = new Intent(view.getContext(), Garage.class);
startActivityForResult(G_intent, 0);
}
});
}
}

我也尝试写另一个应用程序类似于上面的ap折叠。但我只有一个子活动：DiningRoom，然后在手机上运行良好。
的时候我只有一个子活动的背景
[CODE]
public class Test1Activity extends Activity {
private Button Dining_Room;
private Intent D_intent;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Dining_Room = (Button) findViewById(R.id.dining);
// Dining_Room.setBackgroundColor(Color.TRANSPARENT);
Dining_Room.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
D_intent = new Intent(view.getContext(), Dining.class);
startActivityForResult(D_intent, 0);
}
});
}
}
[/ CODE]
“light1”是int。问题在于使用相同的代码“DiningRoom”，但应用程序在它只有一个子活动时运行并且在应用程序有四个子活动时出错 – user1062335 2011-12-17 19:31:57
