Sample code for MainActivity.java
Button b1,b2,b3;
WebView webView;
LinearLayout l1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b1 = (Button)findViewById(R.id.btn1);
b2 = (Button)findViewById(R.id.btn2);
b3 = (Button)findViewById(R.id.btn3);
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
webView = (WebView) findViewById(R.id.webviewing);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("https://www.google.com");
}
});
b2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
webView = (WebView) findViewById(R.id.webviewing);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("https://play.google.com/");
}
});
b2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
webView = (WebView) findViewById(R.id.webviewing);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("https://www.youtube.com/");
}
});
}

Your code works fine, except you set the listener for b2 twice. Typo maybe?
If you are facing connection errors, just add the Internet permission to AndroidManifest.xml.
<uses-permission android:name="android.permission.INTERNET"/>

Change the text message, to be a clikable message

I'm trying to change the text message of the AlertDialog message. To be a clikable message.
With this code the text is blue, but not clikable
I want the phone, email and site from text to be clikable
final SpannableString All =
new SpannableString(textmess + "\n\nTel :\n " + phone + "\n\nEmail : \n " + email + "\n\nAddress: \n " + address + "\n\nWeb site : \n " + site );
Linkify.addLinks(All, Linkify.ALL );
AlertDialog.Builder builder = new AlertDialog.Builder( new
ContextThemeWrapper(context, R.style.AlertDialogCustom) );
builder.setTitle(title).setMessage(All);
builder.create();
//not working
//TextView textView = (TextView) findViewById(android.R.id.message);
builder.show();
GeoPoint1.close();
db1.close();

Create a custom layout for the dialog and also use setMovementMethod to get it done
Ex:
AlertDialog.Builder dialog = new AlertDialog.Builder(context);
LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
View view = inflater.inflate(R.layout.dialog_custom, null);
TextView dTitle = (TextView) view.findViewById(R.id.textDialogTitle);
TextView dMessage = (TextView) view.findViewById(R.id.textDialogMessage);
dMessage.setMovementMethod(LinkMovementMethod.getInstance());
dTitle.setText("Title");
dMessage.setText(ALL);
dialog.setView(view);
dialog.show();

This example will help you :
res/layout/dialog.xml :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

setContentView(R.layout.activity_main);
Button openDialog = (Button) findViewById(R.id.button1);
openDialog.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Dialog dialog = new Dialog(MainActivity.this); // here write the name of your activity in place of "YourActivity"
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.dialog);
TextView tv = (TextView)dialog.findViewById(R.id.tv_pc_dialogTitle);
Typeface tf = Typeface.createFromAsset(getAssets(), "fonts/GOTHIC.TTF"); // here GOTHIC.TTF is the font-file I have pasted in the asset/fonts folder in my project
tv.setTypeface(tf); // Set the typeface like this
Button bt = (Button) dialog.findViewById(R.id.bt_pc_goButton);
bt.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Write here, what do you want to do on button click
}
});
TextView tview = (TextView) dialog.findViewById(R.id.tv_pc_forDialog);
tview.setOnClickListener(new View.OnClickListener() { // set onClickListener to the textview
#Override
public void onClick(View v) {
// Write here, what do you want to do on Message click
Toast.makeText(getApplicationContext(), "You clicked on message", Toast.LENGTH_LONG).show();
}
});
dialog.show();
}
});
}
}
What I have done here is that I made a customised dialog, and set an onClickListener on the TextView shown as a message. Like this, you can achieve your goal.

Dialog is not displaying textview & imageview

I am new to android world and am working on dialog and in that I am trying to create a text view, button and imageview, but it is neither showing me error nor textview or imageview. It is showing a button. Here is the image:
.
But i am want to display my dialogue as follows
My xml file is as follows ....
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF"
tools:context=".AddFriendsCustomActivity">
<ImageView
android:id="#+id/add"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/submit_dialog"
android:layout_alignParentRight="true"
android:layout_marginRight="37dp"
android:contentDescription="#string/add_Friend"
android:src="#drawable/add" />
<Button
android:id="#+id/submit_dialog"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginRight="64dp"
android:layout_toLeftOf="#+id/add"
android:text="#string/submit" />
<EditText
android:id="#+id/writename"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/add"
android:layout_marginRight="17dp"
android:layout_toLeftOf="#+id/add"
android:ems="10" />
</RelativeLayout>
I am calling it in java file as follows
dialog = new Dialog(context);
LayoutInflater li = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = li.inflate(R.layout.activity_add_friends_dialog, null, false);
dialog.setContentView(view);
dialog.setCancelable(true);
//dialog.setContentView(R.layout.activity_add_friends_dialog);
//dialog.setTitle("Add Friends");
add= (ImageView) dialog.findViewById(R.id.add);
friends1 = (TextView) dialog.findViewById(R.id.writename);
submit_dialog = (Button) dialog.findViewById(R.id.submit_dialog);
add.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
try {
friendsCount++;
Log.d("addFriendsActivity", "ashish comes here ");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
submit_dialog.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent i = new Intent(AddFriendsActivity.this, DetailsFriendsActivity.class);
startActivity(i);
}
});
dialog.show();
After some google I understand that the issues might be in r.java or you have imported android .r but i have not done any thing in this ..
Thanks in advance.... :)

There is no error in your java code. Its perfect you have just change your xml. Use this.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF"
tools:context=".AddFriendsCustomActivity" >
<EditText
android:id="#+id/writename"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginTop="24dp"
android:ems="10" >
<requestFocus />
</EditText>
<ImageView
android:id="#+id/add"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/writename"
android:layout_marginLeft="20dp"
android:layout_toRightOf="#+id/writename"
android:contentDescription="Add Friend"
android:src="#drawable/ic_launcher" />
<Button
android:id="#+id/submit_dialog"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignRight="#+id/writename"
android:layout_below="#+id/add"
android:layout_marginRight="46dp"
android:text="Submit" />
</RelativeLayout>

For your xml I think it should look like this:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<EditText
android:id="#+id/my_edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#+id/add_btn" />
<ImageButton
android:id="#+id/add_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:src="#drawable/add_btn"
android:background="#null" />
<Button
android:id="#+id/submit_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_below="#+id/my_edit_text"
android:text="Submit" />
</RelativeLayout>
Be aware that there can be some typo mistakes, because I didn't compile that code, and you should change your real variables. And create your AlertDialog like this:
AlertDialog.Builder mBuilder = new AlertDialog.Builder(MyActivity.this);
View mView = mInflater.inflater(R.layout.my_layout, null, false);
EditText mEdit = (EditText) mView.findViewById(R.id.my_edit_text);
ImageButton mImageBtn = (ImageButton) mView.findViewById(R.id.add_btn);
Button mSubmit = (Button) mView.findViewById(R.id.submit_btn);
mBuilder.setView(mView);
AlertDialog mAlert = mBuilder.create();
mAlert.show();
Using AlertDialog.Builder instead of Dialog is lot more easier for your situation (at least in my opinion). And you can add your Submit Button to your AlertDialog as default positive button.
Hope this helps you.

Look at your code i think
add= (ImageView) dialog.findViewById(R.id.add);
friends1 = (TextView) dialog.findViewById(R.id.writename);
as
add= (ImageView) view.findViewById(R.id.add);
friends1 = (EditText) view.findViewById(R.id.writename);
That should work.

Try this..
final Dialog dialog = new Dialog(AddFriendsActivity.this);
dialog.setContentView(R.layout.activity_add_friends_dialog);
dialog.setCanceledOnTouchOutside(true);
add= (ImageView) dialog.findViewById(R.id.add);
EditText friends1 = (EditText) dialog.findViewById(R.id.writename);
submit_dialog = (Button) dialog.findViewById(R.id.submit_dialog);
add.setOnClickListener(new OnClickListener() {
//#Override
#SuppressWarnings({ "unchecked", "rawtypes" })
#SuppressLint("NewApi")
public void onClick(View v) {
friendsCount++;
//TextView textview = new TextView(context);
//textview.setId(friendsCount);
//final RelativeLayout.LayoutParams params= new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
//params.addRule(RelativeLayout.BELOW, friendsCount--);
//textview.setLayoutParams(params);
//textview.setVisibility(View.VISIBLE);
//relativelayout.addView(textview ,params);
Log.d("addFriendsActivity", "ashish comes here ");
}
});
submit_dialog.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent i = new Intent(AddFriendsActivity.this, DetailsFriendsActivity.class);
startActivity(i);
}
});
dialog.show();

Your view is covered.
May be you can try to set your parent layout to Linearlayout, not RelativeLayout.

button events in dynamic ListAcitvity android

Hi I have generated a dynamic list. I have SeekBar and a ToggleButton for each of the rows in List. I have been trying to generate events for the toggle and seek from the last 1 week but in vain. Please help me with it.
Here is the XML code with the List(smartunits.xml)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/unitsLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/grid_gradient"
android:orientation="vertical" >
<ListView
android:id="#android:id/android:list"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
Now the code for each row(listunits.xml)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="#+id/unitName"
android:layout_width="40px"
android:layout_height="wrap_content"
android:layout_weight="1"
android:padding="20px"
android:textColor="#ffffff" />
<TextView
android:id="#+id/unitCodeId"
android:layout_width="1dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textColor="#ffffff"
android:visibility="invisible" />
<SeekBar
android:id="#+id/unitsseek"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_marginTop="10dp" />
<ToggleButton
android:id="#+id/toggle"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginLeft="5dp"
android:background="#drawable/off_grey"
android:textOff=""
android:textOn="" />
</LinearLayout>
Here is the code for ListActivity
import android.app.ListActivity;
import android.database.Cursor;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.SimpleCursorAdapter;
import android.widget.ToggleButton;
public class UnitsListActivity extends ListActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
// put the bottom code here
setContentView(R.layout.smartunits);
Bundle extras = getIntent().getExtras();
final AutomationDBAccessor db = new AutomationDBAccessor(this);
Cursor cUnits = db.getUnits(extras.getInt("roomFloorId"), extras.getInt("roomId"));
String[] from = new String[] { AutomationDBAccessor.colUnitName, AutomationDBAccessor.colUnitCodeID };
int[] to = new int[] { R.id.unitName, R.id.unitCodeId };
SimpleCursorAdapter sca = new SimpleCursorAdapter(this, R.layout.listunits, cUnits, from, to);
this.setListAdapter(sca);
View viewUnits = LayoutInflater.from(getBaseContext()).inflate(R.layout.listunits, null);
final ToggleButton toggle = (ToggleButton) viewUnits.findViewById(R.id.toggle);
toggle.setOnClickListener(new OnClickListener() {
public void onClick(View v) { // TODO Auto-generated method stub
if (toggle.isChecked()) {
toggle.setBackgroundDrawable(getResources().getDrawable(R.drawable.on));
} else {
toggle.setBackgroundDrawable(getResources().getDrawable(R.drawable.off_grey));
}
}
});
}
}
Now I am unable to handle the ToggleButton events.

I never try this, But you can do something like,
In your listunits.xml
<ToggleButton
android:id="#+id/toggle"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginLeft="5dp"
android:textOff=""
android:textOn=""
android:onClick="toggleButtonClick" />
And in your UnitsListActivity
write this method..
public void toggleButtonClick(View view)
{
ToggleButton toggle = (ToggleButton) view;
if (toggle.isChecked()) {
toggle.setBackgroundDrawable(getResources().getDrawable(R.drawable.on));
} else {
toggle.setBackgroundDrawable(getResources().getDrawable(R.drawable.off_grey));
}
}
Run this code and let me know what happen..
