I am trying to make Alert Dialog Box when internet is not available but I get error that cannot resolve method setButton(java.lang.String, anonymous android.content.DialogInterface.On Click Listener)
The error Shows after setting the OK button, I cannot see the problem but it is linked with import android.support.v7.app.AlertDialog;
Here is my splash activity code:
package com.SplashTest.mk;
import android.app.Activity;
import android.support.v7.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Bundle;
public class SplashActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
setContentView(R.layout.activity_splash);
if(isWorkingInternetPersent()){
splash();
}
else{
showAlertDialog(SplashActivity.this, "No Internet!",
"It looks like you dont have intrenet connection", false);
}
}
public void splash() {
Thread timerTread = new Thread() {
public void run() {
try {
sleep(4000);
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
finish();
}
}
};
timerTread.start();
}
public boolean isWorkingInternetPersent() {
ConnectivityManager connectivityManager = (ConnectivityManager) getBaseContext()
.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivityManager != null) {
NetworkInfo[] info = connectivityManager.getAllNetworkInfo();
if (info != null)
for (NetworkInfo anInfo : info)
if (anInfo.getState() == NetworkInfo.State.CONNECTED) {
return true;
}
}
return false;
}
public void showAlertDialog(Context context, String title, String message, Boolean status) {
AlertDialog alertDialog = new AlertDialog.Builder(context).create();
// Setting Dialog Title
alertDialog.setTitle(title);
// Setting Dialog Message
alertDialog.setMessage(message);
// Setting alert dialog icon
// alertDialog.setIcon((status) ? R.mipmap.ic_launcher : R.mipmap.ic_launcher);
// Setting OK Button
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
finish();
System.exit(0);
}
});
// Showing Alert Message
alertDialog.show();
}}
You are missing the first argument for the method. Try
alertDialog.setButton(DialogInterface.BUTTON_POSITIVE, "OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
finish();
System.exit(0);
}
});

I want to evaluate a Dialog under Android.
My problem is that the Dialog does not wait
with returning a value until I pressed a
button. And when I use a Semaphore the
program hangs at Semaphore.acquire().
Why does it hang at Semaphore.acquire()?
Can you see where I go wrong?
Here is the main activity
package com.example.modaldialog;
import android.app.Activity;
import android.os.Bundle;
import android.widget.Toast;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDialog meinDialog = new mDialog(this);
if (meinDialog.ShowMyModalDialog() == 1)
Toast.makeText(this, "Pressed Button 1",
Toast.LENGTH_LONG).show();
}
}
and here the dialog class
package com.example.modaldialog;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.widget.Toast;
import java.util.concurrent.Semaphore;
import android.app.Activity;
import java.lang.Runnable;
public class mDialog
{
int pressedButtonID;
Activity act;
private final Semaphore dialogSemaphore;
mDialog(Activity act_in)
{
act = act_in;
dialogSemaphore = new Semaphore(0, true);
};
final Runnable mMyDialog = new Runnable()
{
public void run()
{
AlertDialog errorDialog = new
AlertDialog.Builder(act).create();
errorDialog.setMessage("Press a Button!");
errorDialog.setButton("Button2", new
DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
pressedButtonID = 2;
dialogSemaphore.release();
}
});
errorDialog.setButton2("Button1", new
DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
pressedButtonID = 1;
dialogSemaphore.release();
}
});
errorDialog.setCancelable(false);
errorDialog.show();
}
};
public int ShowMyModalDialog() //should be called from non-UI thread
{
pressedButtonID = 0;
act.runOnUiThread(mMyDialog);
try
{
dialogSemaphore.acquire();
}
catch (InterruptedException e)
{
}
return(pressedButtonID);
}
}
I am not much aware about the Semaphore but you can achieve the same with Interface. I have updated your code please find it below,
package com.example.modaldialog;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.widget.Toast;
public class mDialog
{
int pressedButtonID=0;
private HandleDialogEvent dialogEvent;
mDialog(HandleDialogEvent dialogEvent)
{
this.dialogEvent = dialogEvent;
}
public void ShowMyModalDialog() //should be called from non-UI thread
{
pressedButtonID = 0;
AlertDialog errorDialog = new
AlertDialog.Builder(act).create();
errorDialog.setMessage("Press a Button!");
errorDialog.setButton("Button2", new
DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
pressedButtonID = 2;
dialogEvent.getDialogId(pressedButtonID);
}
});
errorDialog.setButton2("Button1", new
DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
pressedButtonID = 1;
dialogEvent.getDialogId(pressedButtonID);
}
});
errorDialog.setCancelable(false);
errorDialog.show();
}
public interface HandleDialogEvent{
public void getDialogId(int Id);
}
}

To achieve the behavior you want, move your call to open Wireless Settings to the MainActivity, and add a boolean variable to its Intent to indicate whether the Settings should be opened in MainActivity.onCreate.
Total Redo Edit
This is your SplashActivity.java. The only problem you should have is the layout name. I don't remember what you named it.
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog.OnClickListener;
import android.content.Context;

import android.util.Log;
import android.widget.Toast;
public class SplashScreen extends Activity
{
static ConnectivityManager cm;
AlertDialog dailog;
AlertDialog.Builder build;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);// checking
build = new AlertDialog.Builder(this);
setContentView(R.layout.activity_splash);
// if connection is
// there screen goes
// to next screen
// else shows
// message
if (cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI).isConnectedOrConnecting()
|| cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).isConnectedOrConnecting())
{
Log.e("cm value", "" + cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI)
.isConnectedOrConnecting());
Toast.makeText(this, "Internet is active", 2000).show();
Thread mythread = new Thread() {
public void run()
{
try
{
sleep(5000);
}
catch (Exception e)
{
}
finally
{
Intent intent = new Intent(SplashScreen.this,
MainActivity.class);
startActivity(intent);
finish();
}
}
};
mythread.start();
}
else
{
build.setMessage("This application requires Internet connection. Would you connect to internet ?");
build.setPositiveButton("Yes", new OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which)
{
// TODO Auto-generated method stub
Intent intent = new Intent(SplashScreen.this,

}
});
build.setNegativeButton("No", new OnClickListener() {
#Override

build.setMessage("Are sure you want to exit?");
build.setPositiveButton("Yes", new OnClickListener() {

dialog.dismiss();
}
});
dailog = build.create();

And this is your MainActivity.
import android.app.Activity;

ToggleButton toggle;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toggle = (ToggleButton)findViewById(R.id.tglbtn1);
toggle.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
if (toggle.isChecked())
{
Toast.makeText(getApplicationContext(), "Boosting For Next 60 Minutes, Minimize the Application", Toast.LENGTH_LONG).show();
}
else
{
Toast.makeText(getApplicationContext(), "Boosting Turned Off", Toast.LENGTH_LONG).show();
}
}
}
);
Intent intent = getIntent();
boolean show = intent.getBooleanExtra("showSettings", false);
if (show)
{
startActivity(new Intent(Settings.ACTION_WIRELESS_SETTINGS));
}
}
}
Fix the layout name issue in SplashScreen and you should be good. I just ran this code and it performs as expected.
Basic question, what did i do? Hahaha. What did i do to make url load inside webview?
At first i overridden shouldOverrideUrlLoading to control where the link loads, then i one time i removed it but url still loads inside webview. And now i need to once again override url loading because i need a link to be opened on the default browser, but i don't know how. I even tried what others suggested to force url loading on the default browser, but it doesn't work. Please help me. Here's my code:

Should i include manifest? Thanks in advance.
let's say you want to handle caturl
then, in
if (url.contains(caturl){
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(mycaturl));
startActivity(i);
}
I have a webview, yes i do. :)
Anyway, I load my main URL fine, but i need to load another url programmatically at some point. The problem is that it somewhat opens another webview, and I know this because when I exit the app using finish() method, the webview with the latter url closes, but another webview stays open. What should I do? Should i call destroy webview or something else?
I just load them URLs using webview.loadUrl(url here) method.

Should I also include manifest? Thanks in advance.
Put this in your web Activity :
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
Then set :
your_webview.setWebViewClient(new MyWebViewClient());
Hope this will help you
Without the necessary code I have to assume this is what you need to add to your implementation.
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
webview.loadUrl(url);
return true;
}
My Alert dialog message doesn't come out because I cannot get the text of the button. After that the program will directly go to my EventActivity. How can settle this problem?
public void onClick(View v) {
// TODO Auto-generated method stub
if (v.getId() == insertButton.getId()) {
if(colorButton.getText().toString().equals("Color")){
colorAlert.show();
}
}
}
This is variable
AlertDialog colorAlert;
AlertDialog in the OnCreate()
AlertDialog.Builder CA = new AlertDialog.Builder(this);
CA.setTitle("Alert Message!");
CA.setMessage("Please insert the level of important for the event.");
CA.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
colorAlert.dismiss();
startActivity(new Intent(this, EventActivity.class));
}
});
colorAlert = CA.create();
When you compare a String in Java, use YOUR_STRING.equals("Color");
Update:
change your while into if , because your are running it once.
The move your
startActivity(new Intent(this, EventActivity.class));
in your alertbox positive button handler.

Ok look like you need more help, here is one solution... i let you deal with the EventActivity ;)
import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Context;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.widget.*;
public class MainActivity extends Activity {
final Context context=this;
public static String EXTRA_MESSAGE;
Button colorButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_test);
colorButton = (Button) findViewById(R.id.button1);
colorButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(colorButton.getText().toString().equals("Color")){
AlertDialog.Builder alertBuilder = new AlertDialog.Builder(context);
alertBuilder.setMessage("myDialog").setCancelable(false).setPositiveButton("yes", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
Intent intent = new Intent(MainActivity.this, EventActivity.class);
String message = colorButton.getText().toString();
intent.putExtra(EXTRA_MESSAGE, message);
startActivity(intent);
}
}).setNegativeButton("cancel", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog myAlert = alertBuilder.create();
myAlert.show();
}
}
});
}
Adding to wtsang02 answer, you shouldn't put your alert.show in a while like this one... I see coming the infinite loop ;)
