안드로이드 쓰레드 진행상황 프로그래스바로 보여주기

프로그래스 대화상자

 

프로그래스바가 있는 대화상자를 만들어봅시다.

 

 

xml은 위와 같습니다.

 

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

> 

<TextView

android:id="@+id/text"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="0"

android:textSize="40sp"

/>

<Button

android:id="@+id/update"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:onClick="mOnClick"

android:text="Update"

/>

</LinearLayout>

 

 

 

자바파일.
