我看過其他Q和答案，但找不到我的代碼有什麼問題嗎？我一定在做錯事，所以如果有人能幫助我，那將是非常感謝。我檢查了第一頁和第二頁以及清單。Android應用程序不斷崩潰按鈕點擊

請發佈堆棧跟蹤 – Emmanuel

發佈'LogCat' – Rick

查找了跟蹤文件錯誤，但發現它通常是由'setContentView（R.layout.activity_main）'引起的;'在錯誤的地方，但我很確定它在適合我的地方？ – user3028988

沒有堆棧跟蹤可能很難說。從我看到你有兩個可能的罪魁禍首。

首先

Bundle extras = getIntent().getExtras(); 
public final String ID_CITY = extras.getString("CITY_TH");

在你的搜索類，你正試圖從包中獲取數據。但是在你的MainActivity.goMenu（）中，你沒有傳入一個包。這可能會導致NULLPOINTEREXCEPTION

二

setupActionBar();

請嘗試評論說出來你Search.class和看到的結果是什麼。我無法從清單中看到您的主題。所以你甚至可能沒有可能導致崩潰的操作欄。所以，如果註釋掉上述工程線路，以下內容添加到您的清單：

變化：

android:theme="@style/AppTheme"

要：

android:theme="@android:style/Theme.Holo"

，看看是否可行。

打敗我吧。絕對值得評論這兩行，看看問題是否消失。 – Squonk

此外，一旦這些工作，他們應該被移動像一個方法像'onCreate（）' – codeMagic

我一直在試圖將清單更改爲'android：theme =「@ style/Theme.Holo」'但我保持發現沒有找到資源的錯誤？ @Brianjs – user3028988

的問題應該是這樣的：

button.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View arg0) { 
       goMenu(); 
     } 

    }); 
} 


public void goMenu() 
{ 
    Intent myIntent = new Intent(this, Search.class); 
    startActivity(myIntent); 
}

剛剛嘗試替換此：

button.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Intent myIntent = new Intent(MainActivity.this,Search.class); 
      MainActivity.this.startActivity(myIntent); 

     } 
    });

希望它可以幫助你。

謝謝，但我最初有你的建議，並將其更改爲當前的一個試圖解決問題，所以我不認爲這是它（雖然你的可能更好）。 @ user2675569 – user3028988
