i seem to have encountered a problem here.. i have the 2 edittext boxes and one button. when i click the button it gives me an option of what way to send the message, however it does not capture what my inputs are but gives out a weird message saying This is a Testandroid.widget.EditText#47b84299android.widget.EditText#47b8f0d9. Neither does it go to email and fill up the subject header.
this is my code.

now i want to display name of trainees which is stored in database. can anyone help me??
If you want to see how a Cursor loader can work for you, you can review the following project that I have uploaded to github: GPS Distance Tracking
I have a problem with the concatenation of the strings that I will I enter.
This is the class:
package com.isma.multisitesearch.Siti;
import com.isma.multisitesearch.R;
import com.isma.multisitesearch.Webviews.GoogleWebView;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class Google extends Activity implements OnClickListener {
private String TAG_ACT = "Caricamento ricerca";
public EditText googletext;
private Button googlebutton;
private String googleurl = "https://www.google.it/search?q=";
public static String newgoogleurl;
public String space = " ";
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.google);
googletext = (EditText) findViewById(R.id.googletext);
googlebutton = (Button) findViewById(R.id.googlebutton);
googlebutton.setOnClickListener(this);
newgoogleurl = googleurl + googletext.getText().toString();
newgoogleurl.replaceAll(space, "%20");
System.out.println(newgoogleurl);
}
#Override
public void onClick(View v) {
Log.v(TAG_ACT, "in corso");
Intent intent = new Intent(Google.this, GoogleWebView.class);
startActivity(intent);
}
}
And this is the WebView to which I want to get the concatenation:
package com.isma.multisitesearch.Webviews;
import com.isma.multisitesearch.R;
import com.isma.multisitesearch.Siti.Google;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class GoogleWebView extends Activity {
private WebView googlewebview;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.googlewebview);
googlewebview = (WebView) findViewById(R.id.googlewebview);
googlewebview.getSettings().setJavaScriptEnabled(true);
googlewebview.getSettings().setLoadsImagesAutomatically(true);
googlewebview.setWebViewClient(new WebViewClient());
googlewebview.loadUrl(Google.newgoogleurl);
}
}
The app works fine but when I go to write the search text in the EditText, the google but I get the main page where you can enter the search instead of the url with already entered the search text.
I hope you know to help me, after this I was able to run the app.
Try this:
#Override
public void onClick(View v) {
newgoogleurl = googleurl + googletext.getText().toString();
newgoogleurl = newgoogleurl.replaceAll(space, "%20");
Log.v(TAG_ACT, "in corso");
Intent intent = new Intent(Google.this, GoogleWebView.class);
startActivity(intent);
}
Note that
newgoogleurl.replaceAll(space, "%20");
has no effect, you need to code:
newgoogleurl = newgoogleurl.replaceAll(space, "%20");
Have a look here:
http://javarevisited.blogspot.it/2011/12/java-string-replace-example-tutorial.html
Try below code:
String url;
url = googleurl+googletext.getText().toString();
if( url.contains(" ")){
newgoogleurl=url.replaceAll(" ","%20");
}else{
newgoogleurl=url;
}
This is containing validation part also.
Strings are immutable. That means that you cannot modify an instance of String, and need to create a new one each time you want to modify it.
In your case, replaceAll does not modify the String you call it on, but rather returns a new String with your modification applied.
Which is why you need to affect the returned value to the reference of your String.
newgoogleurl = newgoogleurl.replaceAll(space, "%20");
Moreover, you should read the documentation for replaceAll, because I don't think it does what you want. You probably want to use replace.
In my example, i am entering mobile no., message content in one activity. Before leaving that activity i am saving that info in "Shared Preference". In other activity i am trying to get those mob no,message,i am able to get no but unable to getting that message(second value).please help me to solve the issue.

Here def no getting message as Couldn't load data
please help me
Replace with this:
DefaultData = getSharedPreferences("defMobileNo",0);
final String defNo = DefaultData.getString("defMobileNo","Couldn't load data");
final String defMsg = DefaultData.getString("defMessgae","Couldn't load data");
This is how basically sharedpreference work
To Store the values
SharedPreferences preferences = getSharedPreferences("AUTHENTICATION_FILE_NAME", Context.MODE_WORLD_WRITEABLE);
SharedPreferences.Editor editor = preferences.edit();
editor.putString("Name","myNameisnothing");
editor.commit();
To get the values
SharedPreferences prfs = getSharedPreferences("AUTHENTICATION_FILE_NAME", Context.MODE_PRIVATE);
String name = prfs.getString("Name", "");
This way it'd return the value of the name as myNameisnothing.
PS.Correct me if im wrong.
You are wrongly using
DefaultData = getSharedPreferences("defMessgae",0); in DefSMS.java
Please remove this and it will work fine.
You were trying to get shared preference named defMessgae which doesnot even exist. So when you try to access it, android will create a new preference with default value. That is why you were getting "Couldn't load data"

<Button android:id="#id/button3" android:onClick="buttonhandler" ... />
I am developing an application in which I have to send an image through email. I succeeded in sending email, but the attachment sent is of 0KB size. I am not getting what is the problem. Below, I am posting my code.

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

Button email;
Intent in;
private static final String TAG = "EmailLauncherActivity";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
email = (Button)findViewById(R.id.email);
email.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
try {
in = new Intent(Intent.ACTION_SEND);
in.setType("image/jpeg");
in.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/android.jpg"));
startActivity(Intent.createChooser(in, "Email..."));
} catch (Exception e) {
Log.e(TAG, "email sending failed", e);
}//catch
}//onClick
});
}//onCreate
}//class
I also face the same problem which is solved by changing MIME type.
Try this in.setType("image/jpg");
Was your phone mounted to your computer at the time? The SD card may be inaccessible while connected to your computer, so it may not actually be attaching the image.
