I have a activity in that I need to change the layout.
In the first layout I have four buttons to display and in the second I need a GridView to display images.
I need to show the second layout in an AsyncTask onPostExecute method.
For now, I'm trying to set two setContentViews, but I get the following exception: ClassCastException
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_focusarea);
videoBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
new LoadFiles().execute();
}
});
animateBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
new LoadFiles().execute();
}
});
pdfBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
new LoadPDFFiles().execute();
}
});
}
And in my postExecute i try like this
protected void onPostExecute(String file_url) {
pDialog.dismiss();
runOnUiThread(new Runnable() {
public void run() {
setContentView(R.layout.gallery);
girGridView=(GridView) findViewById(R.id.gridView1_bir);
girGridView.setAdapter(new ImageAdapter(this));
girGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int position,long arg3) {
Toast.makeText(getApplicationContext(), GridViewConfig.getResim_list().get(position), Toast.LENGTH_SHORT).show();
}
});
}
});
Instead of using two layouts use a single layout as bellow
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/MyLayoutOne"
android:layout_width="fill_parent"
android:visibility="gone"
android:layout_height="fill_parent" >
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="Hi This is my first layout" />
<!-- Your first layout contents add here-->
</LinearLayout>
<LinearLayout
android:id="#+id/MyLayoutTwo"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="Hi This is my Second layout" />
<!-- Your second layout contents add here -->
</LinearLayout>
</LinearLayout>
Add your first layout contents inside MyLayoutOne and second layout contents inside MyLayoutTwo
And use following codes inside your activity,
public class MainActivity extends Activity {
LinearLayout MyLayoutOne;
LinearLayout MyLayoutTwo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MyLayoutOne=(LinearLayout)findViewById(R.id.MyLayoutOne);
MyLayoutTwo=(LinearLayout)findViewById(R.id.MyLayoutTwo);
// this will make first layout visible
MyLayoutOne.setVisibility(View.VISIBLE);
// this will make second layout hidden from your layout
MyLayoutTwo.setVisibility(View.GONE);
//=========================================
//in your post create add this codes
//=========================================
// this will make first layout hidden
MyLayoutOne.setVisibility(View.GONE);
// this will make second layout visible in your layout
MyLayoutTwo.setVisibility(View.VISIBLE);
//=========================================
}
}
This is a simplest method you must study fragments for better UI management. You can use viewflipper also.
So Study Fragments and Viewflipper..
Instead of that you can have a layout that contains both a wrapper for your four buttons and other for the GridView while this last one is with visibility set to 'gone'.
When the AsycTask finished, you hide the buttons layout and show the GridView layout.
Why don't you set one content view with two layouts or two fragments? A layout can be like this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="#string/text1">
</Button>
<Button
android:id="#+id/button2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="#string/text2">
</Button>
<Button
android:id="#+id/button3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="#string/text3">
</Button>
<Button
android:id="#+id/button4"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="#string/text4">
</Button>
<GridView
android:layout_width="match_parent"
android:layout_height="wrap_content"
...
</GridView>
</LinearLayout>
Use one setContentView() and define separates Linear/Relative layout one for buttons and second for gridView.And hide/show the Views according to your need.
onPostExecute of AsyncTask runs on UI thread so you need not specify runonUiThread explicitly.Instead of using 2 setcontent View it is better to have 2 views in your layout file and make it visible invisible as required.
Friend change the id of wrapper1 to child as below,
<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="match_parent"
tools:context=".Focusarea" >
<LinearLayout
android:id="#+id/wrapper1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:visibility="gone" >
<GridView
android:id="#+id/gridView1_bir"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center" >
</GridView>
</LinearLayout>
<RelativeLayout
android:id="#+id/wrapper2"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:id="#+id/vid_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="18dp"
android:src="#drawable/ic_launcher" />
</RelativeLayout>
</LinearLayout>
and initialize your linear layouts outside oncreate as below,
LinearLayout wrapper1;
RelativeLayout wrapper2;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
wrapper1 = (LinearLayout)findViewById(R.id.wrapper1);
wrapper2=(RelativeLayout)findViewById(R.id.wrapper2);
// this will make first layout visible
wrapper2.setVisibility(View.VISIBLE);
// this will make second layout hidden from your layout
wrapper1.setVisibility(View.GONE);
ImageView videoBtn = (ImageView) findViewById(R.id.vid_btn);
ImageView animateBtn = (ImageView) findViewById(R.id.anit_btn);
ImageView pdfBtn = (ImageView) findViewById(R.id.pdf_btn);
videoBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
new LoadFiles().execute();
}
});
animateBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
new LoadFiles().execute();
}
});
pdfBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
new LoadPDFFiles().execute();
}
});
}
protected void onPostExecute(String file_url) {
// dismiss the dialog after getting VIDEOS
pDialog.dismiss();
vid=new ArrayList<String>(new ArrayList<String>(vid));
videoUrl=parsing.parse(videoUrl);
System.out.println("VIDEO URL" +videoUrl);
runOnUiThread(new Runnable() {
public void run() {
//--here you wont need to initialize again--
// this will make first layout visible
wrapper1.setVisibility(View.VISIBLE);
// this will make second layout hidden from your layout
wrapper2.setVisibility(View.GONE);
girGridView=(GridView) findViewById(R.id.gridView1_bir);
//ListView gibi buna da adapter set ediliyor.
girGridView.setAdapter(new ImageAdapter(this));
girGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int position,long arg3) {
Toast.makeText(getApplicationContext(), GridViewConfig.getResim_list().get(position), Toast.LENGTH_SHORT).show();
}
});
}
});

I have a Linearlayouts, a ScrollView and a button, I am not able to figure out why when I programmatically add a Checkbox to the Linearlayout, at the end of the view, the method from the scrollview
scrollview.scrollto(0, ScrollView.FOCUS_DOWN);
will not focus the last item added.
here the XML
<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="match_parent"
android:orientation="vertical"
android:weightSum="100"
tools:context="com.eidotab.myapplication.MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:orientation="vertical"
android:padding="10dp"
android:layout_weight="30">
<ScrollView
android:id="#+id/scroll"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/linear"
android:gravity="center"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</LinearLayout>
</ScrollView>
</LinearLayout>
<Button
android:id="#+id/boton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="TEST"/>
</LinearLayout>
and here the java:
public class MainActivity extends AppCompatActivity {
ScrollView scrollView;
LinearLayout linearLayout;
Button button;
int num = -1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
scrollView = (ScrollView) findViewById(R.id.scroll);
linearLayout = (LinearLayout) findViewById(R.id.linear);
button = (Button) findViewById(R.id.boton);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
num++;
CheckBox checkBox = new CheckBox(getApplicationContext());
checkBox.setText("TEST " + num);
checkBox.setTextColor(Color.BLACK);
linearLayout.addView(checkBox);
scrollView.fullScroll(ScrollView.FOCUS_DOWN);
}
});
}
}
Im also addind the .rar so you just have to download it and try it.. I have spent several hours trying to make it work.. also tried to get the specific child from the LinearLayout with the
y = Linearlayout.getchildat(N).getBottom();
and works similar to the FOCUS_DOWN... I can never see the very last item.. only the item before the last.
Thanks in advance for the help.
Here is the program
https://www.dropbox.com/home/Public?preview=MyApplication.rar
Well after some research, seems like there is some kind of problem when trying to perform scrolls programmatically and the solution I have found that work best is to add a runable inside the onClick method in my code so I added
scrollView.post(new Runnable() {
#Override
public void run() {
scrollView.fullScroll(ScrollView.FOCUS_DOWN);
}
});
and the end result was
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
num++;
CheckBox checkBox = new CheckBox(getApplicationContext());
checkBox.setText("TEST " + num);
checkBox.setTextColor(Color.BLACK);
linearLayout.addView(checkBox);
//scrollView.fullScroll(ScrollView.FOCUS_DOWN);
scrollView.post(new Runnable() {
#Override
public void run() {
scrollView.fullScroll(ScrollView.FOCUS_DOWN);
}
});
}
});
it is now working flawlessly but that said, I don´t think it is the ideal solution.
Hello this is my xml file
<RelativeLayout
android:id="#+id/tutorialBox"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="15dip"
android:paddingBottom="15dip">
<Button
android:id="#+id/closeBen"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="#string/CloseBenny"
android:layout_alignBottom="#+id/bennybox"
android:layout_alignEnd="#+id/chatbub" />
</RelativeLayout>
i have made an on click listener for it
final Button closeBt = (Button) findViewById(R.id.closeBen);
closeBt.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
closeBt.setText("Im a button");
}
});
for some reason when i click this button nothing happens it doesnt look like it has been clicked.
when i took the button out of the realtive layout everything worked fine
any suggestions?
Instead of this add onClick attribute to the button tag in xml.
<Button
android:id="#+id/closeBen"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="#string/CloseBenny"
android:onClick = "close_clicked"
android:layout_alignBottom="#+id/bennybox"
android:layout_alignEnd="#+id/chatbub" />
Then in Main Activity just make a new method like this.
public void close_clicked (View v){
// Your code
}
No need to add on click listner.
Your RelativeLayout does not look good, is it your main container? Maybe try it this way
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin">
<Button
android:id="#+id/closeBen"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="#string/CloseBenny"
android:layout_alignBottom="#+id/bennybox"
android:layout_alignEnd="#+id/chatbub" />
</RelativeLayout>
And a good practice is to declare your widgets globally then instantiate them in theOnCreate
public class Foo extends AppCompatActivity {
private Button closeBenny;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
closeBenny = (Button)findViewById(R.id.closeBen);
closeBenny.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
closeBenny.setText("Im a button");
}
});
}
}
i want to have two relativelayout in first relativelayout have map and in second relativelayout i have the list..,i want on starting only layout with map will be visible on screen with a button,,when i click on button then layout with listview get open from right side with new new button on the top of it,,and prevoius button get hide.and screen get divided with two parts with different layouts..i have done some thing but from starting onward m getting half half screen.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</RelativeLayout>
</LinearLayout>
MainActivity
show = (TextView)findViewById(R.id.getdirection);
show1 = (TextView)findViewById(R.id.hide);
rt = (RelativeLayout)findViewById(R.id.rl_ListView2);
show.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(rt.getVisibility()==View.INVISIBLE)
{
rt.setVisibility(View.VISIBLE);
}
show.setVisibility(View.INVISIBLE);
}
});
show1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(rt.getVisibility()==View.VISIBLE)
{
rt.setVisibility(View.INVISIBLE);
}
show1.setVisibility(View.INVISIBLE);
}
});
Try this:
You are getting layout1 in half screen from starting due to weight property. You can try not giving weight in starting and give it programatically on button click.
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
button1.setVisibility(View.GONE); //hide old button
layout2.setVisibility(View.VISIBLE); //show layout2
//set Relativelayout 1 to half screen
RelativaLayout.LayoutParams params = layout1.getLayoutParams();
params.weight = 0.5;
layout1.setLayoutParams(params);
}
});
Hope this helps.
Set visibility as Gone instead of Invisible
button.setOnClickListener(this);
public void onClick(View v) {
layoutid.setVisibility(View.GONE);
}
You can try with isShown() as suggested by Amiya
<b>
button2.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view) {
if(button1.isShown()) {
// Your_Staff
}
else{
// Your_Staff
}
}
});
</b>
From my view you did not set the orientation in the LinearLayout to be vertical for the two RelativeLayouts. I also suggests you put the map and Button in a FrameLayout as well instead of RelativeLayout.
I a new to Android development, so this is kind of a basic question.
I would like to implement the same behavior as in the Contacts app. You have a ListView with a series of Contacts | phone icons. There you have one behavior when you click on the contact name, and another behavior when you click on the phone icon.
Here is my code.
Any help is much appreciated.
In summary, what is wrong with the approach
switch (v.getId()) {
case R.id.imageButtonAction:
Activity Class
public class CompaniesActivity extends Activity {
MyApp app;
ListView listCompanies;
Cursor cursor;
// Adapter and its corresponding FROM and TO statements. The number and sequence of the arguments must match in FROM / TO arguments.
SimpleCursorAdapter adapter;
static final String[] FROM = { MenuNavigationData.C_COMPANY, MenuNavigationData.C_DESCRIPTION};
static final int[] TO = { R.id.textCompany, R.id.textDescription }; //
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.companies);
//Gets a reference to the application
app = (MyApp) getApplication();
// Find your views
listCompanies = (ListView) findViewById(R.id.listCompanies);
addButton = (Button) findViewById(R.id.buttonAdd);
// Add actions to user interaction
listCompanies.setOnItemClickListener(new OnItemClickListener() {
#Override
**public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
switch (v.getId()) {
case R.id.imageButtonAction:
startActivity(new Intent(app, InstructionsActivity.class));
break;
default:
int i = adapter.getItemViewType(position);
startActivity(new Intent(app, EditMenuNavigationActivity.class));
break;
}**
}
});

Your onItemClick() callback receives both the specific view as well as its position (0-based), each of these can help you decide which view was clicked. The position is an index into the items you've added, and for more complicated scenarios you can view.setTag(Object o), and use getTag() to retrieve it from your callback.
New much better approach to solve this issue elegantly, and with less code!!!
With the following modifications, the User interface is much more responsive, no more double-clicking issues. :)
Much, much less code that simply works!
Modifications to Row xml
Insert a Linear layout to wrap both the
In this Linear layout, insert a tag named android:onClick="editCompanyClick"
This is the click handler that will be called in the Activity.

I finally found a solution.
This solves the issue. But adds another one. As expected, the ListView now behaves differently when the user clicks on different views(either TextView or ImageView).
But it seems unresponsive. I have to "double-click" in order to trigger either the company.setOnClick or dial.setOnClick. Any suggestions?
// Add actions to user interaction
listCompanies.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
TextView company = (TextView) v.findViewById(R.id.textCompany);
ImageView dial = (ImageView) v.findViewById(R.id.imageButtonDTMFDial);
company.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(app, EditMenuNavigationActivity.class));
}
});
dial.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(app, InstructionsActivity.class));
}
});
}
How would you do something like "Touch Anywhere to Continue."
Set an onclick listener for the layout of the entire screen
It's as simple as this.
Give an id to "main" layout
set the listener to the main layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:id="#+id/mainLayout"> //<--- Provide ID
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
/>
</RelativeLayout>
In this case, the main element is RelativeLayout. So add the listener to RelativeLayout to implement Touch anywhere to continue.
public class MainActivity extends AppCompatActivity {
private RelativeLayout layout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
layout = (RelativeLayout)findViewById(R.id.mainLayout);
layout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "Clicked", Toast.LENGTH_SHORT).show();
}
});
}
}
