Android键盘的显示控制、网络检查、网络监测，android网络监测

一、经常会用到隐藏输入键盘与显示键盘的操作，这里贴出控制代码：

//关闭键盘舒服法
		 public static void collapseSoftInputMethod(Context context, View v) {
		        if (v != null) {
		            InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
		            imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
		        }
		    }

		    //显示输入法
		 public static void showSoftInputMethod(Context context, View v) {
		        if (v != null) {
		            InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
		            imm.showSoftInput(v, 0);
		        }
		   }

二、检查网络是否可用

	/**
	 * @Name: checkNetwork
	 * @Description: 检查当前网络
	 * @param: 无
	 * @return: true--有网络 false---无网络
	 */
	public boolean checkNetwork() {
		ConnectivityManager conn = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
		NetworkInfo net = conn.getActiveNetworkInfo();
		if (net != null && net.isConnected()) {
			return true;
		}
		return false;
	}

检查wifi是否可用

public boolean isWifiConnected(Context context) { 
if (context != null) { 
ConnectivityManager mConnectivityManager = (ConnectivityManager) context 
.getSystemService(Context.CONNECTIVITY_SERVICE); 
NetworkInfo mWiFiNetworkInfo = mConnectivityManager 
.getNetworkInfo(ConnectivityManager.TYPE_WIFI); 
if (mWiFiNetworkInfo != null) { 
return mWiFiNetworkInfo.isAvailable(); 
} 
} 
return false; 
}

三、检查移动网络是否可用

public boolean isMobileConnected(Context context) { 
if (context != null) { 
ConnectivityManager mConnectivityManager = (ConnectivityManager) context 
.getSystemService(Context.CONNECTIVITY_SERVICE); 
NetworkInfo mMobileNetworkInfo = mConnectivityManager 
.getNetworkInfo(ConnectivityManager.TYPE_MOBILE); 
if (mMobileNetworkInfo != null) { 
return mMobileNetworkInfo.isAvailable(); 
} 
} 
return false; 
}

四、检查当前网络类型

public static int getConnectedType(Context context) { 
if (context != null) { 
ConnectivityManager mConnectivityManager = (ConnectivityManager) context 
.getSystemService(Context.CONNECTIVITY_SERVICE); 
NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo(); 
if (mNetworkInfo != null && mNetworkInfo.isAvailable()) { 
return mNetworkInfo.getType(); 
} 
} 
return -1; 
}
