如何更改日曆對話框的顏色Android

Question

在我的應用程序中，我使用DatePicker對話框和時間選擇器對話框來相應地選擇日期和時間。現在，在那些對話框中，根據我的Themecolor設置顏色。但我想做什麼，是手動改變這些顏色。例如，我改變了工具欄的顏色，以這種方式toolbar.setBackgroundColor（Constant.color）;但是，如何以同樣的方式手動更改標題顏色（當前日期顯示 - 我已附加圖片）和日期選擇器顏色（指示當前日期的圓形選擇器）。

這裏是我的日期選擇器的對話框代碼

public class TodoAddActivity extends AppCompatActivity { 

// Variables 
private Context mContext; 

.... 

private RealmResults<TodoModel> results; 

public final static String INTENT_KEY_ID = "taskId";

    app_preferences = PreferenceManager.getDefaultSharedPreferences(this); 
    appColor = app_preferences.getInt("color", 0xff3F51B5); 
    appTheme = app_preferences.getInt("theme", 0xff3F51B5); 
    themeColor = appColor; 
    constant.color = appColor; 

    if (themeColor == 0){ 
     setTheme(Constant.theme); 
    }else if (appTheme == 0){ 
     setTheme(Constant.theme); 
    }else{ 
     setTheme(appTheme);

Answer 1

new DatePickerDialog(MainActivity.this, R.style.DialogTheme, new DatePickerDialog.OnDateSetListener() { 
@Override 
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { 
    //Your Code 
} 
}, year, monthOfYear, dayOfMonth).show(); 

編輯 - 更改主題Theme.AppCompat .Light.Dialog建議

<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog"> 
     <item name="colorAccent">@color/xyz</item> 
</style> 

Answer 2

試着這樣做：

在你styles.xml添加以下內容：

<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog"> 
    <item name="colorAccent">@color/yourColor</item> 
</style> 

然後在你的日期選擇器做到這一點，而不是。

DatePickerDialog mDatePickerDialog = new DatePickerDialog(mContext, R.style.DialogTheme, new DatePickerDialog.OnDateSetListener()
