クイズの進行状況バー（Androidスタジオ）

Question

私はクイズゲームを作成しており、進行状況バーを追加しました。プログレスバーに各質問に10秒間答えてもらい、時間がなくなると結果画面が表示されます。 どうすればよいですか？

Answer 1

あなたの活動では、実行中のスレッド、あなたの活動のXMLで について

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="vertical" android:layout_width="match_parent" 
android:layout_height="match_parent"> 
<ProgressBar 
    style="@android:style/Widget.ProgressBar.Horizontal" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_margin="10dp" 
    android:progress="100" 
    android:id="@+id/progress"/> 
</LinearLayout> 

を実行中のスレッドやAsyncTask 1）を使用することができ

public class TestActivity extends AppCompatActivity{ 

private ProgressBar moveBar; 
private int count; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_test); 

    moveBar = (ProgressBar)findViewById(R.id.progress); 
    moveBar.setProgress(100); 

    startProgress(); 

} 

private void startProgress() { 

    Thread sleep = new Thread(new Runnable() { 
     @Override 
     public void run() { 
      for(count =10; count >=0; count --) { 

       try { 
        Thread.sleep(1000); //every 1sec 

        // here you check for the result if correct 
        //i use count == 5 as an example, uncomment to see 
        /*if(count == 5){ 
         count = 10; 
         moveBar.setProgress(100); 
         startProgress(); 
         break; 
        }*/ 
       }catch (Exception i){ 
        i.printStackTrace(); 
       } 
       runOnUiThread(new Runnable() { 
        @Override 
        public void run() { 
         moveBar.setProgress(10 * count); 
         Log.e("Count", " " + count); 


         if(count == 0){ 
          Toast.makeText(getApplicationContext(), 
            "Result screen", Toast.LENGTH_SHORT).show(); 
         } 
        } 
       }); 

      } 
     } 
    });sleep.start(); 
} 
}
