CountDownTimer - ProgressBarが90％で停止する（Java）

Question

ボタンをクリックして10秒後にProgressBarを入力したいと思います。問題は、ProgressBarの進行状況が約90％で停止していることです。

public void klick(View v){ 

    mProgressBar=(ProgressBar)findViewById(R.id.progressbar); 
    mProgressBar.setProgress(i); 
    mProgressBar.setMax(100); 
    mCountDownTimer=new CountDownTimer(10000,100) { 

     @Override 
     public void onTick(long millisUntilFinished) { 
      Log.v("Log_tag", "Tick of Progress; i:"+ i+ "// "+ millisUntilFinished); 
      i++; 
      mProgressBar.setProgress(i); 

     } 

     @Override 
     public void onFinish() { 
      //Do what you want 
      b1.setText("Finished"); 
     } 
    }; 
    mCountDownTimer.start(); 
} 

なぜ停止しますか？私のコードではonTick()が0.1秒ごとに10秒間実行されると考えていたので、i = 100は10秒後に発生します。

Answer 1

これはあなたの問題を解決するために生成するコードですが、私は多くの数字を試しましたが、私は最初のティックとして3から始めなければならないと思います。時々この時間は9860に変更されました）しかし、これは平均ですので、我々は2つのダニが見当たらないことを発見します。

Tick of Progress; i:4// 9797

あなたが必要とする第二の部分は、ここで

   @Override 
      public void onTick(long millisUntilFinished) { 
       // 100 is the max value  
       i = 100 - (int) millisUntilFinished/100 ; 
       mProgressBar.setProgress(i); 

     Log.v("Log_tag", "Tick of Progress; i:" + i + "// " + millisUntilFinished); 

      } 

      @Override 
      public void onFinish() { 
       //you will figure you lost tick 
       // so I handle it with i++ 
       Log.v("Log_tag", "Last tick : " +i); 
       mProgressBar.setProgress(i++); 
       mtextview.setText("Finished"); 
      } 

UPDATE_ANSWERは、Javaコードであり、

のJavaのログを1つの目盛り以上を失うことを避けるためにonFinishで進捗状況を更新コード

private ProgressBar mProgressBar; 
private CountDownTimer mCountDownTimer; 
int i = 3; 
TextView mtextview; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    mtextview = (TextView) findViewById(R.id.textview); 
    klick(); // handle tick as you wish 
} 

public void klick() { 

    mProgressBar = (ProgressBar) findViewById(R.id.progressbar); 
    mProgressBar.setProgress(i); 
    mProgressBar.setMax(100); 
    mCountDownTimer = new CountDownTimer(10000, 100) { 

     @Override 
     public void onTick(long millisUntilFinished) { 
      Log.v("Log_tag", "Tick of Progress; i:" + i + "// " + millisUntilFinished); 
      i++; 
      mProgressBar.setProgress(i); 

     } 

     @Override 
     public void onFinish() { 
      //Do what you want 
      Log.v("Log_tag", "Last tick : " +i); 
      mProgressBar.setProgress(i); 
      mtextview.setText("Finished"); 
     } 
    }; 
    mCountDownTimer.start(); 
}

Answer 2

の前にタイマーが完了したので、私は最後のティックは到着しないと仮定します。最後のステップ（「確信してください」）のためにonFinishの進捗バーを設定しないでください。
