MyTimerCheck.java

package home.mft;


public abstract class MyTimerCheck {
	private int mCount = 0;
	private int mTimeOutCount = 1;
	private int mSleepTime = 1000; // 1s
	private boolean mExitFlag = false;
	private Thread mThread = null;
	
	/**
	 * Do not process UI work in this.
	 */
	public abstract void doTimerCheckWork();
	
	public abstract void doTimeOutWork();
	
	public MyTimerCheck() {
		mThread = new Thread(new Runnable() {
			
			public void run() {
				// TODO Auto-generated method stub
				while (!mExitFlag) {
					mCount++;
					if (mCount < mTimeOutCount) {
						doTimerCheckWork();
						try {
							mThread.sleep(mSleepTime);
						} catch (InterruptedException e) {
							// TODO Auto-generated catch block
							e.printStackTrace();
							exit();
						}
					} else {
						doTimeOutWork();
					}
				}
			}
		});
	}
	
	/**
	 * start
	 * @param times  How many times will check?
	 * @param sleepTime ms, Every check sleep time.
	 */
	public void start(int timeOutCount, int sleepTime) {
		mTimeOutCount = timeOutCount;
		mSleepTime = sleepTime;
		
		mThread.start();
	}
	
	public void exit() {
		mExitFlag = true;
	}
	
}

然后是调用 HomeIndex.java

package home.mft;

import hotspot.mft.R;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

import android.app.Activity;
import android.content.Context;
import android.net.wifi.WifiConfiguration;
import android.net.wifi.WifiManager;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class HomeIndex extends Activity {
	private Button button1;
    /** Called when the activity is first created. */
	
	private Context mContext = null;
	
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mContext = HomeIndex.this;
        setContentView(R.layout.main);
        button1 = (Button)findViewById(R.id.button1);
        button1.setOnClickListener(new View.OnClickListener() {
			public void onClick(View v) {
				// TODO Auto-generated method stub
				
				WifiApAdmin wifiAp = new WifiApAdmin(mContext);
				wifiAp.startWifiAp("mftAP", "123456789");
				
				//\
			}
		});
        
        //\\
    }
}
