Android: Afzal ekrandagi tugmalardan qanday foydalanish kerak

TimePicker vidjetini o‘z ichiga olgan maxsus DialogPreference yarating. Hech qanday tugma kerak emas. Kodning 100 qatoridan kam bo'lishi kerak.

Bu yerda namunaviy loyiha, boshqa narsalar qatori, maxsus ColorPreference.

Siz tugmani activity_layout.xml ga qo'yishingiz mumkin. Misol uchun, agar "Activity_Setup.java" sizning sozlash faoliyatingiz bo'lsa, "activity_setup.xml" uning tartibi va "myprefs.xml" sizning afzal ko'rgan joyingiz saqlanadigan fayl bo'lsa, u holda

Siz tugmani ro'yxat ostidagi "activity_setup.xml" ga qo'yishingiz kerak, eng yaxshisi TableRow-da, masalan:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:id="@+id/llprefs">

<ListView
    android:id="@+id/android:list"
    android:tag="lvprefs"
    android:layout_width="match_parent"
    android:layout_height="0.0dp"
    android:layout_weight="1" >
</ListView>

    <TableRow
    android:id="@+id/tableRow1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="20dp"
     >

    <Button
        android:id="@+id/btRegister"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:text="@string/IdonothaveA"
        android:onClick="onClick"
         />

    <Button
        android:id="@+id/btForgot"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:text="@string/Iforgot"
        android:onClick="onClick" />
   <!--  
    <Button
        android:id="@+id/btContact"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:text="@string/Contact"
        android:onClick="onClick" />
     -->

</TableRow>
