Android 开启网络

主要是通过Intent来调用开启网络的Activity。

 

private boolean CheckNetwork() {boolean flag = false;ConnectivityManager cwjManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);if (cwjManager.getActiveNetworkInfo() != null)flag = cwjManager.getActiveNetworkInfo().isAvailable();if (!flag) {Builder b = new AlertDialog.Builder(this).setTitle("没有可用的网络").setMessage(getResources().getString("请开启GPRS或WIFI网络连接"));b.setPositiveButton("确定", new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int whichButton) {Intent mIntent = new Intent("/");ComponentName comp = new ComponentName("com.android.settings", "com.android.settings.WirelessSettings");mIntent.setComponent(comp);mIntent.setAction("<span class="hilite">android</span>.intent.action.VIEW");startActivity(mIntent);}}).setNeutralButton("取消", new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int whichButton) {dialog.cancel();}}).create();b.show();}return flag;}
