Close Custom Dialog from another function

I am trying to modify the layout of a dialog and then perform some function and close the alert box as my function is over.
Layout File
<LinearLayout
android:layout_width="match_parent"
android:layout_height="120dp"
android:orientation="horizontal"
android:layout_below="#+id/header"
android:paddingTop="15dp"
android:paddingBottom="15dp">
<ImageView
android:id="#+id/cam"
android:layout_width="0dp"
android:layout_height="match_parent"
android:padding="10dp"
android:paddingLeft="10dp"
android:src="#drawable/ic_cam"
android:layout_alignParentLeft="true"
android:layout_weight="1"
android:onClick="camera_listener"
/>
<ImageView
android:id="#+id/gal"
android:layout_width="0dp"
android:layout_height="match_parent"
android:padding="10dp"
android:paddingLeft="10dp"
android:src="#drawable/ic_gal"
android:layout_alignParentLeft="true"
android:layout_weight="1"
android:onClick="gallery_listener"
/>
</LinearLayout>
Java File
AlertDialog.Builder myAlertDialog; // Variable declared as a class member
private void startDialog() {
LayoutInflater inflater = this.getLayoutInflater();
final View view = inflater.inflate(R.layout.activity_fab, null);
myAlertDialog = new AlertDialog.Builder(this);
myAlertDialog.show();
}
public void gallery_listener(View view) {
pictureActionIntent = new Intent(Intent.ACTION_PICK, null);
pictureActionIntent.setType("image/*");
pictureActionIntent.putExtra("return-data", true);
startActivityForResult(pictureActionIntent, GALLERY_PICTURE);
myAlertDialog.setOnDismissListener();
}
public void camera_listener(View view) {
pictureActionIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
pictureActionIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(pictureActionIntent, CAMERA_REQUEST);
}
I'm displaying two images in dialog and defining function on their click... i want to close the DIALOG as soon as corresponding function is performed.
I tried using dismiss but it is not working..!

try this in your second method,
in Main.java
import android.app.Activity;
import android.os.Bundle;
import android.support.v7.app.AlertDialog;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;
public class DialogCustom extends Activity {
AlertDialog myAlertDialog;
ImageView ivOne,ivTwo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dialog_custom);
ivOne=(ImageView)findViewById(R.id.cam);
ivTwo=(ImageView)findViewById(R.id.gal);
myAlertDialog = new AlertDialog.Builder(this).create();
ivOne.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
startDialog();
}
});
ivTwo.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
runOnUiThread(new Runnable() {
#Override
public void run() {
dismis();
}
});
}
});
}
private void startDialog() {
myAlertDialog.show();
}
public void dismis()
{
myAlertDialog.dismiss();
}
}
and in main.xml file.
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="120dp"
android:layout_below="#+id/header"
android:orientation="horizontal"
android:paddingBottom="15dp"
android:paddingTop="15dp" >
<ImageView
android:id="#+id/cam"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_weight="1"
android:onClick="camera_listener"
android:padding="10dp"
android:paddingLeft="10dp"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/gal"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_weight="1"
android:onClick="gallery_listener"
android:padding="10dp"
android:paddingLeft="10dp"
android:src="#drawable/ic_launcher" />
</LinearLayout>

Alternate i found... is first create a alert dialog using builder then assign that to a dialog and use dismiss function with that
Update-
private AlertDialog dialog; // Variable with class scope
private void startDialog() {
LayoutInflater inflater = this.getLayoutInflater();
final View view = inflater.inflate(R.layout.activity_fab, null);
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setCancelable(true);
builder.setView(view);
dialog = builder.create();
dialog.show();
}
public void gallery_listener(View view) {
pictureActionIntent = new Intent(Intent.ACTION_PICK, null);
pictureActionIntent.setType("image/*");
pictureActionIntent.putExtra("return-data", true);
startActivityForResult(pictureActionIntent, GALLERY_PICTURE);
dialog.dismiss();
}
This has worked for me... if there is any better method plz share!

Not able to figure out what am i doing wrong, i updated android studio and downloaded API 22 and after that i got many errors in My gradle too. I some how fixed that but it is run time error how can i fix please help me out.

Is your activity added in the manifest?

use getSupportActionBar() instead of getActionBar().
Use
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
Instead of
getActionBar().setDisplayHomeAsUpEnabled(true);
and run the app again.

Android custom control is this possible?

Im searching this since yesterday. I've got on many Activities some piece of code which displays user name and login. I dont want to copy and paste code in layout into every Activity, but I want something just like user controls in .NET. I've read a lot of topic about custom controls but or I don't understand it or its not possible do to this (I dont belive in that option)

Yes it is possible. Look at this sample. It is a custom Numeric Keyboard or a custom View or a custom user control. Customize it and create your own user control:
import java.util.ArrayList;
import org.mabna.order.R;
import android.app.Activity;
import android.content.Context;
import android.text.InputType;
import android.util.AttributeSet;
import android.view.LayoutInflater;

import android.view.View.OnTouchListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.LinearLayout;
// this NumericKeyboard works only for EditTexts which
// have a tag with "usesNumericKeyboard" key and value of "true"
// use tag with "ignoreMeForNumericKeyboardTouchListener" key and
// value "true" for controls you do not want to set its touchListener
public class NumericKeyboard extends LinearLayout implements OnTouchListener {

ontouch and onclick on a textview not working

have a look at the code below...
i am setting the onclick listener on the textview and the ontouch listener but none of them is working...
what seems to be the problem>....?
AlertDialog.Builder builder;
AlertDialog a;
TextView text,txtNewUser ;
ImageView image;
View layout;
Button ok;
String pswrd;
LayoutInflater inflater;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
final Context mContext = this;
Dialog dialog = new Dialog(mContext);
inflater = (LayoutInflater) mContext
.getSystemService(LAYOUT_INFLATER_SERVICE);
ok = (Button) findViewById(R.id.buttonOK);
dialog.setContentView(R.layout.custom_dialog_private_space);
dialog.setTitle("Password");
dialog.setCancelable(true);
layout = inflater.inflate(R.layout.custom_dialog_private_space,
(ViewGroup) findViewById(R.id.layout));
text = (TextView) dialog.findViewById(R.id.tvDesc);
txtNewUser = (TextView) dialog.findViewById(R.id.tvNewUser);
image = (ImageView) layout.findViewById(R.id.image);
image.setImageResource(R.drawable.lock_symbol_android);
builder = new AlertDialog.Builder(mContext);
builder.setView(layout);
a = builder.create();
a.show();
txtNewUser.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
if(event.getAction() == MotionEvent.ACTION_UP)
Toast.makeText(mContext, "Clicked", Toast.LENGTH_SHORT).show();
Log.v("AS", "Clicked");
return true;
}
});
txtNewUser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(mContext, "Clicked", Toast.LENGTH_SHORT).show();
Log.v("AS", "Clicked");
}
});

here is the code of textview from the xml of the dialog layout

Instead of infalter use window class
return false in on Touch listener
set contenet view to your main activity
package com.collabera.labs.sai;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.util.Log;
import android.view.MotionEvent;
import android.view.View;
import android.view.Window;
import android.view.View.OnTouchListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
public class HomePage extends Activity {
AlertDialog.Builder builder;
AlertDialog a;
TextView text, txtNewUser;
ImageView image;
Button ok;
String pswrd;
public Window mWindow;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.custom_dialog_private_space);
ok = (Button) findViewById(R.id.buttonOK);
final Context mContext = this;
Dialog dialog = new Dialog(HomePage.this);
dialog.setContentView(R.layout.custom_dialog_private_space);
dialog.setTitle("Password");
dialog.setCancelable(true);
dialog.show();
mWindow = dialog.getWindow();
Log.w(" dialog is " + mWindow.toString(), "-------");
text = (TextView) mWindow.findViewById(R.id.tvDesc);
txtNewUser = (TextView) mWindow.findViewById(R.id.tvNewUser);
image = (ImageView) mWindow.findViewById(R.id.image);
image.setImageResource(R.drawable.icon);
txtNewUser.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP)
Toast.makeText(mContext, "Touched", Toast.LENGTH_SHORT)
.show();
Log.v("AS", "Touched");
return false;
}
});
txtNewUser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(mContext, "Clicked", Toast.LENGTH_SHORT).show();
Log.v("AS", "Clicked");
}
});
}
}

I think.. you should also return
return super.onTouchEvent(event);
from onTouch function.. instead of true because true means the event is consumed by touch and other actions are not called for this event.. in this case onClick

this is the way i used to make imageview clickable:
public class Main extends Activity **implements OnClickListener** {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView profile_btn=(ImageView) findViewById(R.id.x_Btn);
x_btn.setOnClickListener(this) ;
ImageView food_btn=(ImageView) findViewById(R.id.y_Btn);
ybtn.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId())
{
case R.id.x_Btn:
//do some thing;break;
case R.id.y_Btn:
//do some thing;break;
}
}
}

In toast both cases you have written clicked so change to touch in onTouch listener and return false at onTouch Listener:
public class HomePage extends Activity {
private TextView txtNewUser;
private Context mContext;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mContext = getApplicationContext();
txtNewUser = (TextView) findViewById(R.id.tvNewUser);
txtNewUser.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
if (event.getAction() == MotionEvent.ACTION_UP)
Toast.makeText(mContext, "Touched ", Toast.LENGTH_SHORT)
.show();
Log.v("AS", "Touched");
return false;
}
});
txtNewUser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(mContext, "Clicked", Toast.LENGTH_SHORT).show();
Log.v("AS", "Clicked");
}
});
}

connect activitys

Can some one tell me were i am going wrong. i have three activity's that i want to connect togever. This code is my first java file and first xml file. i think my onclick code some where is not right. my end result is that all 3 activity connect with 3 image buttons...thank
java 1.code
package my.hope;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;
import android.content.Intent;
public class NewhopeActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView myImage = (ImageView) findViewById(R.id.imageButton1);
myImage.setOnClickListener(new OnClickListener() {
intent intent = new intent(Newhopeactivity.this, Act2.class);
startActivity(intent);
public void onClick(View v) {
// TODO Auto-generated method stub
}
}
);
}
}
xml.code
<?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"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/bt" />
<ImageButton
android:id="#id/imageButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher"
android:onClick="Act2"/>

You have to put the startActivity() into the actual onClick() method.
myImage.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
intent intent = new intent(Newhopeactivity.this, Act2.class);
startActivity(intent);
}
}

Change
ImageView myImage = (ImageView) findViewById(R.id.imageButton1);
myImage.setOnClickListener(new OnClickListener() {
intent intent = new intent(Newhopeactivity.this, Act2.class);
startActivity(intent);
public void onClick(View v) {
// TODO Auto-generated method stub
}
}
to
ImageView myImage = (ImageView) findViewById(R.id.imageButton1);
myImage.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new intent(Newhopeactivity.this, Act2.class);
startActivity(intent);
}
}
