Android 连接Wifi和创建Wifi热点 demo

android的热点功能不可见，用了反射的技术搞定之外。

Eclipse设置语言为utf-8才能查看中文注释

上代码：

MainActivity.java

package com.widget.hotspot;

import android.os.Bundle;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity {

	public static final String TAG = "MainActivity";
	
	private Button mBtn1, mBtn2;
	
	private WifiAdmin mWifiAdmin;
	
	private Context mContext = null;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		
		mContext = this;
		
		setContentView(R.layout.activity_main);
		
		mBtn1 = (Button)findViewById(R.id.button1);
		mBtn2 = (Button)findViewById(R.id.button2);
		mBtn1.setText("点击连接Wifi");
		mBtn2.setText("点击创建Wifi热点");
		mBtn1.setOnClickListener(new Button.OnClickListener() {
			
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub

				mWifiAdmin = new WifiAdmin(mContext) {
					
					@Override
					public void myUnregisterReceiver(BroadcastReceiver receiver) {
						// TODO Auto-generated method stub
						MainActivity.this.unregisterReceiver(receiver);
					}
					
					@Override
					public Intent myRegisterReceiver(BroadcastReceiver receiver,
							IntentFilter filter) {
						// TODO Auto-generated method stub
						MainActivity.this.registerReceiver(receiver, filter);
						return null;
					}
					
					@Override
					public void onNotifyWifiConnected() {
						// TODO Auto-generated method stub
						Log.v(TAG, "have connected success!");
						Log.v(TAG, "###############################");
					}
					
					@Override
					public void onNotifyWifiConnectFailed() {
						// TODO Auto-generated method stub
						Log.v(TAG, "have connected failed!");
						Log.v(TAG, "###############################");
					}
				};
				mWifiAdmin.openWifi();
				mWifiAdmin.addNetwork(mWifiAdmin.createWifiInfo("YOU_WIFI", "MM123456", WifiAdmin.TYPE_WPA));
				
			}
		});
		
		mBtn2.setOnClickListener(new Button.OnClickListener() {
			
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				
				WifiApAdmin wifiAp = new WifiApAdmin(mContext);
				wifiAp.startWifiAp("\"HotSpot\"", "hhhhhh123");
			}
		});
		
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.activity_main, menu);
		return true;
	}

	 @Override
	    public void onResume() {
	        super.onResume();
	        
	        Log.d("Rssi", "Registered");
	    }

	    @Override
	    public void onPause() {
	        super.onPause();
	        
	        Log.d("Rssi", "Unregistered");
	    }
	
}
