标签：android   延时   wifi连接检测   

Android检测系统WIFI是否连接？如没有连接，显示提示框，提示进行设置，当点击设置进入系统WIFI界面后1秒钟，提示框自动消失。

代码：

public boolean isWifiConnected(Context context) {
		ConnectivityManager connectivityManager = (ConnectivityManager) context
				.getSystemService(Context.CONNECTIVITY_SERVICE);
		NetworkInfo wifiNetworkInfo = connectivityManager
				.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
		if (wifiNetworkInfo.isConnected()) {
			return true;
		} else {
			builder.setMessage("请检查WIFI是否连接成功！");
			builder.setTitle("提示信息");
			builder.setPositiveButton("设置",
					new DialogInterface.OnClickListener() {
						public void onClick(final DialogInterface dialog,
								int which) {
							Intent intent = new Intent(
									Settings.ACTION_WIFI_SETTINGS);
							startActivity(intent);
							//点击设置1秒后消失
							new Handler().postDelayed(new Runnable() {
								@Override
								public void run() {
									dialog.dismiss();
								}
							}, 1000);
						}
					});

			builder.setNegativeButton("取消",
					new android.content.DialogInterface.OnClickListener() {
						public void onClick(DialogInterface dialog, int which) {
							dialog.dismiss();
						}
					});
			dialog = builder.create();
			dialog.show();
			return false;
		}
	}
