我在android活動中的對話崩潰，我錯過了什麼？

-2

這是我的OnClickListener其中i超載我的方法稱爲我在android活動中的對話崩潰，我錯過了什麼？

DialogueSuccessful();

應啓動的臺詞。

if (Inserted == true) { 
    DialogueSuccessful(); 
    txt_FromDate.setText(""); 
    txt_ToDate.setText(""); 
    txt_total_payment.setText(""); 
} else { 
    Toast.makeText(getApplicationContext(), "Did not Insert Data", Toast.LENGTH_LONG).show(); 
}

這裏是我的方法實現，方法的具體實現過程中的應用程序崩潰

public void DialogueSuccessful() { 
    AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext()); 
    builder.setMessage("Successfull") 
     .setTitle("Hotels Reservation") 
     .setPositiveButton("Nice", new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog, int id) { 
       // FIRE ZE MISSILES! 
      } 
     }); 
    // Create the AlertDialog object and return it 
    AlertDialog Dialogue = builder.create(); 
    Dialogue.show(); 
}

這是我在logcat的例外：

這是所有的代碼，我使用啓動我的期望的臺詞，我應該添加任何東西嗎？

幫我一個忙，如果ü請，您的幫助將不勝感激謝謝

更改方法簽名'公共無效DialogueSuccessful（查看視圖）'如果使用'機器人：的onclick = 「DialogueSuccessful」'以xml –

此外代替使用'getApplicationContext（）'使用當前活動上下文創建AlertDialog –

謝謝，切換到活動上下文是成功的 –

從

getApplicationContext()

切換到活動上下文是succesul

public void DialogueSuccessful(){ 
    AlertDialog.Builder builder = new AlertDialog.Builder(this); 
    builder.setMessage("Successfull") 
      .setTitle("Hotels Reservation") 
      .setPositiveButton("Nice", new DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface dialog, int id) { 
        // FIRE ZE MISSILES! 
       } 
      }); 
    // Create the AlertDialog object and return it 
    AlertDialog Dialogue=builder.create(); 
    Dialogue.show(); 
}

在AndroidManifest.xml檔案活動標籤添加

android:theme="@style/Theme.AppCompat.Light"

。

我認爲你已經在xml-layout文件中使用onClick屬性。你也沒有使用適合你的項目的主題。顯示你的XML或應用主題活動。

修改您dialogueSuccessful方法

替換此線

AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());

與

AlertDialog.Builder builder =new AlertDialog.Builder(
    new ContextThemeWrapper(getApplicationContext(), android.R.style.Theme_Dialog));
