Add a call button to an Android App

Question

I'm trying to add a call button. Which would be button14. All the other buttons open a WebActivity file that has the strings as links in it.

I'm real new to programming in Android. I had someone help me create the app in the first place but he is out of town and I need to get this done. Any help would be great!!

package com.myapp.programname;

import com.myapp.programname.R;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

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

    public void onButton(View view) {

        int index = -1;
        int id = view.getId();

        if (id == R.id.button1) {

            index = 0;
        }
        else if (id == R.id.button2) {

            index = 1;
        }
        else if (id == R.id.button3) {

            index = 2;
        }
        else if (id == R.id.button4) {

            index = 3;
        }
        else if (id == R.id.button5) {

            index = 4;
        }
        else if (id == R.id.button6) {

            index = 5;
        }
        else if (id == R.id.button7) {

            index = 6;
        }
        else if (id == R.id.button8) {

            index = 7;
        }
        else if (id == R.id.button9) {

            index = 8;
        }
        else if (id == R.id.button10) {

            index = 9;
        }
        else if (id == R.id.button11) {

            index = 10;
        }
        else if (id == R.id.button12) {

            index = 11;
        }
        else if (id == R.id.button13) {

            index = 12;
        }
        else if (id == R.id.button14) {

            Intent callIntent = new Intent(Intent.ACTION_CALL);
            callIntent.setData(Uri.parse("tel:123456789"));
            startActivity(callIntent);
        }

        else {

            index = 0;
        }

        Intent intent = new Intent(this, WebActivity.class);
        intent.putExtra("link", index);
        this.startActivity(intent);
    }
}

Here is the WebActivity Code Also

package com.myapp.programname;

import com.myapp.programname.R;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class WebActivity extends Activity {

    private class MyWebViewClient extends WebViewClient{

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {

            return false;
        }
    }

    String links[] = {"http://somesite.com",
            "http://somesite.com",
            "http://somesite.com",
            "http://somesite.com",
            "http://somesite.com",
            "http://somesite.com",
            "http://somesite.com",
            "http://somesite.com",
            "http://somesite.com,
            "http://somesite.com",
            "http://somesite.com",
            "http://somesite.com",
            "http://somesite.com"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_web);

        int index = getIntent().getIntExtra("link", 0);
        WebView myWebView = (WebView) findViewById(R.id.webview);
        myWebView.getSettings().setJavaScriptEnabled(true);
        myWebView.getSettings().setLoadWithOverviewMode(true);
        myWebView.getSettings().setUseWideViewPort(true);
        myWebView.getSettings().setBuiltInZoomControls(true);
        myWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
        myWebView.setWebViewClient(new MyWebViewClient());
        myWebView.loadUrl(links[index]);
    }

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

}

You can use the default built-in Android "call application" or whatever the user wants to use. To do this use an implicit intent and eventually put in the bundle additional information, like the number to call. — type-a1pha, Jul 19 '13 at 20:47

You can prepare a Intent for a phone call and launch it like this...

String phoneNumber = "555-555-5555";
Intent callintent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:" + phoneNumber));
startActivity(callIntent);

And don't forget to include this permission in your AndroidManifest.xml file...

<uses-permission android:name="android.permission.CALL_PHONE" />

Reference from this question.
