無限循環掛在運行（） - 方法（Android模擬器）

我們正試圖建立一個應用程序，每秒鐘左右記錄分貝級別。問題是我們需要在run（）方法中有一個無限循環來輪詢分貝級別，但是當我們添加無限循環時，它會掛起。任何人都可以將我們指向正確的方向嗎？謝謝。無限循環掛在運行（） - 方法（Android模擬器）

下面的代碼：

package tpsip.tpsip; 

import android.app.Activity; 
import android.graphics.Color; 
import android.media.AudioManager; 
import android.media.ToneGenerator; 
import android.os.Bundle; 
import android.os.Handler; 
import android.widget.Button; 
import android.widget.TextView; 


public class tpsip extends Activity implements Runnable{ 

private TextView decibelMeter; 
private TextView timeRemaining; 
private Button button; 
private int safetyTime; 


ExposureCalculator calculator = new ExposureCalculator(); 
Handler handler = new Handler(); 
Thread thread = new Thread(); 
LogicLayer logicLayer = new LogicLayer(); 


/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 

    this.safetyTime = 28800; //8 hours of safe time when the decibel level is between 90-92, levels below this are not considered dangerous to hearing 

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    this.decibelMeter = (TextView)findViewById(R.id.textView2); 
    this.decibelMeter.setText("0 dB"); 

    this.timeRemaining = (TextView)findViewById(R.id.textView3); 
    this.timeRemaining.setText("Safety time remaining " + safetyTime + " seconds"); 

    this.button = (Button) findViewById(R.id.button1); 
    button.setBackgroundColor(Color.GREEN); 
    button.setText("Ear protection not needed"); 

    handler.post(thread); 

    this.run(); 

} 

@Override 
public void run() { 
     int a = 10; 
    while(true) { 
     this.decibelMeter.setText("0safsafsafa dB"); 
     if (a == Math.random() * 100) break; 
    } 
} 
}
