當我在模擬器上運行我的應用程序時，它運行正常，沒有問題發生。但是當我在手機上運行它時，出現的問題「意外停止」。當在手機上運行時，應用程序「意外停止」
在我的申請： 主要活動（背景）可以交換到4個活動：客廳，DiningRoom，Wc，車庫。當我嘗試去DiningRoom活動時，問題「意外停止」。
這是我的代碼：
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);
}
});
}
}

我也嘗試寫另一個應用程序類似於上面的ap摺疊。但我只有一個子活動：DiningRoom，然後在手機上運行良好。
的時候我只有一個子活動的背景
[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。問題在於使用相同的代碼「DiningRoom」，但應用程序在它只有一個子活動時運行並且在應用程序有四個子活動時出錯 – user1062335 2011-12-17 19:31:57
