In another activity I wanted to call the lat and long of the above code but don't want to rewrite the code to the activity. I just want to call it and display the result in another activity. please help. thanks
make your variable static and define it before onCreate() method use that variable in another activity by call like this.
YourMainActivity.yourstaticvariable
after long googling days, no success.
i just want to get the first number from "result=0.23 562"
here is my code, i will appreciate any help!

I've been trying to import a very simple project I've started on a differnt laptop but for some reson the project now is full of errors.
Eclipse does not recognize imports being made and thus refuse to recognize simple classes as ActionBarActivity and methods like onCreate.
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.Toast;
import android.os.Build;
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment()).commit();
}
}
#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;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**

*/
public static class PlaceholderFragment extends Fragment {
public PlaceholderFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container,
false);
return rootView;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
Button bEnter=(Button) getActivity().findViewById(R.id.bEnter);
Button bSignup=(Button) getActivity().findViewById(R.id.bSignup);
bEnter.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String toastText="It's Working!!!";
int toastDuration=Toast.LENGTH_SHORT;
Toast toast=Toast.makeText(getActivity(), toastText, toastDuration);
toast.show();
}
});
}
}
}
What am I missing here??
What errors are you getting ?
Trick1:
If the appcompat_v7 project(library) is causing the problem, remove it from the project properties, then perform the following steps.
1) Right click on the main.
2) Hover over Android Tools.
3) Click 'Add Support Library'.
It will download the required library and the clean the project. It should work.
if doesn't work, let me know.
Trick2: Update to the latest Revisions ( Tools and SDKs using SDK manager)
Happy Coding.
I am bran new to this but I have successfully created a functional button.
I am attempting to pass user input (editText1 on activity_main) to Recipe (my second activity) The first code is my functional button. What am I doing wrong in the second round of code in my attempt at passing information to be displayed on the second activity layout?
package com.example.andrew;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button b=(Button) findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener() {
public void onClick(View v){
startActivity(new Intent(MainActivity.this, Recipe.class));
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
Second round of code: My attempt at passing information. First activity
package com.example.andrew;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Edit Text et = (Edit Text) findViewById(R.id.editText1);
String theText = et.getText().toString();
Intent i = new Intent(this, Recipe.class);//Recipe is my second class
i.putExtra("text_label", theText);//what is "text_label"? Where should it be?
Button b=(Button) findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener() {
public void onClick(View v){
startActivity(new Intent(MainActivity.this, Recipe.class));
}
});
}
}
And in my second activity I have:
public class Recipe extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.recipe_layout);
Intent i = getIntent();
uriStringi = i.getStringExtra("text_label");//is text_label on actv. 1?
startActivity(i);
}
You are adding data in the intent but while starting the activity you are not using it. Instead creating new intent.
Solution:
In your current Activity, create a new Intent:
Intent i = new Intent(this, Recipe.class);
i.putExtra("text_label", theText);
startActivity(i); // Write this in onClick()
Then in the Recipe, retrieve those values:
Bundle extras = getIntent().getExtras();
if (extras != null) {
String value = extras.getString("text_label");
}
I would like to open url´s in webview instead of in a webbrowser. I´m no programmer and can´t find a solution. Help would be greatly apreciated. I would like the url to open in a new activity called: activity_webview. Thanks in advance
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import com.casovi.luxury_new.R;
public class MainCars extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cars);
}
public void GoKoenigsegg(View view) {
goToUrl("http://www.koenigsegg.com/");
}
public void GoMercedes(View view) {
goToUrl("http://www.mercedes-amg.com/#/home");
}
private void goToUrl(String url) {
Uri uriUrl = Uri.parse(url);
Intent launchBrowser = new Intent(Intent.ACTION_VIEW, uriUrl);
startActivity(launchBrowser);
}
}
}
Make your main activity like this:
first create a webview,
second enable webviewclients,
third enable contentview,
finally load your desired url.
All the best..
public class MainCars extends Activity {
WebView web;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
web = (WebView) findViewById(R.id.webView1);
web = new WebView(this);
web.getSettings().setJavaScriptEnabled(true);
web.loadUrl("http://www.koenigsegg.com/");
web.setWebViewClient(new myWebClient());
web.setWebChromeClient(new WebChromeClient());
setContentView(web);
}
