프로그래스바를 이용하여 진행도 알려주기

0. 응용한 기술

- 해당 섹션이 완료되면, 그 섹션만큼 진행도를 증가시키는 것.

( 여기서는 섹션을 sleep()을 주었다. )

( 구현하고 싶다면, sleep()을 진행시키고 여러 쓰레드를 수행하면 된다. )

 

 

 

 

1. 구현해야 할 것

 

 

 

2. 제약조건

- 없음.

 

 

 

3. java 소스코드

 

( 아래는 MainActivity.java의 코드이다. )

package com.example.exercise001;

import android.app.ProgressDialog;
import android.content.Context;
import android.os.Bundle;
import android.os.Handler;
import android.os.Looper;
import android.view.View;
import android.widget.Button;
import android.widget.ProgressBar;
import android.widget.Toast;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity implements Runnable{
    static ProgressDialog dialog;
    static ProgressBar progressBar;
    static Context mContext;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        progressBar = findViewById(R.id.progressBar);
        progressBar.setIndeterminate(false);
        mContext = getApplicationContext();

        Button btn1 = findViewById(R.id.btn1);
        btn1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog = new ProgressDialog(MainActivity.this);
                dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
                dialog.setMessage("메시지를 전송중입니다.");
                dialog.setTitle("알림");
                progressBar.incrementProgressBy(30);
                dialog.show();

                try{
                    //ThreadEX1 t1 = new ThreadEX1();
                    //t1.start();

                    MainActivity m = new MainActivity();
                    Thread t1 = new Thread(m);
                    t1.start();
                }catch (Exception e) {

                }finally {
                    printStr("전송 중...");
                }
            }
        });

        Button btn2 = findViewById(R.id.btn2);
        btn2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                progressBar.setProgress(0);
            }
        });
    }

    public void printStr(String msg){
        Toast.makeText(getApplicationContext(), msg, Toast.LENGTH_SHORT).show();
    }

    @Override
    public void run() {
        try {
            if(progressBar.getProgress() == 100){
                progressBar.setProgress(30);
            }
            Thread.sleep(2000);
            progressBar.incrementProgressBy(10);
            Thread.sleep(1000);
            progressBar.incrementProgressBy(15);
            Thread.sleep(300);
            progressBar.incrementProgressBy(15);
            Thread.sleep(300);
            progressBar.incrementProgressBy(20);
            Thread.sleep(1000);
            progressBar.incrementProgressBy(10);
            dialog.dismiss();
        } catch (Exception e) {
            e.printStackTrace();
        }finally {
            Handler handler = new Handler(Looper.getMainLooper());
            handler.postDelayed(new Runnable() {
                @Override
                public void run()
                {
                    Toast.makeText(mContext, "전송 완료", Toast.LENGTH_SHORT).show();
                }
            }, 0);
        }
    }
}

 

 

 

4. xml 소스코드

 

( 아래는 activity_main.xml의 코드이다. )

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">


    <ProgressBar
        android:id="@+id/progressBar"
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:max="100" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal">

        <Button
            android:id="@+id/btn1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="보여주기" />

        <Button
            android:id="@+id/btn2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="리셋" />
    </LinearLayout>
</LinearLayout>
