btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (btn.getText()=="More") {
btn.setText("Less"); tl.setVisibility(v.VISIBLE);
}
else
{
btn.setText("More"); tl.setVisibility(v.GONE);
}
}
});
}
give me the solutions.

Try with equalsIgnoreCase Like this to be more precise
if (btn.getText().toString().equalsIgnoreCase("More")) {...}

Change this:
if (btn.getText()=="More") {...}
to this:
if (btn.getText().toString().equals("More")) {...}

check if view is visible or not onClick of TextView:
if(panelProfile.getVisibility() == View.VISIBLE) {
panelProfile.setVisiblity(View.GONE);
} else {
panelProfile.setVisiblity(View.VISIBLE);
}
Note: You are declaring below code multiple times, instead just do it only once.
View panelProfile = findViewById(R.id.panelProfile);
same with,
View panelSettings = findViewById(R.id.panelSettings);
View panelPrivacy = findViewById(R.id.panelPrivacy);

Try this:
Globally define String Variable in which you need to store your different Spinner Selected Values.
Suppose you have 3 Spinners:
Then Define like:
String Spinner1Value,Spinner2Value,Spinner3Value;
before your
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
.....
}
Now on Every Spinner setOnItemSelectedListener():
spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int position,
long id) {
try
{
Spinner1Value= spinner1.getSelectedItem().toString();
}
catch(Exception e)
{
Toast.makeText(getBaseContext(), "Error::"+e.toString(), Toast.LENGTH_LONG).show();
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
and after that you can get the selected values from Spinner1Value,Spinner2Value,Spinner3Value.
Like:
edittext1.setText(Spinner1Value+Spinner2Value+Spinner3Value);
Hope this may help you!

Custom Alignment of RadioButtons in Android

I have 4 RadioButtons (part of same RadioGroup) and I want to align them like this :
Code I am using is :
<RadioGroup
android:id="#+id/add_reminder_type"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="#dimen/zero"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_horizontal"
android:orientation="vertical" >
<RadioButton
android:id="#+id/add_reminder_daily"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/add_reminder_daily" />
<RadioButton
android:id="#+id/add_reminder_weekly"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/add_reminder_weekly" />
</LinearLayout>
<LinearLayout
android:layout_width="#dimen/zero"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_horizontal"
android:orientation="vertical" >
<RadioButton
android:id="#+id/add_reminder_monthly"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/add_reminder_monthly" />
<RadioButton
android:id="#+id/add_reminder_yearly"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/add_reminder_yearly" />
</LinearLayout>
</RadioGroup>
But by using this code, RadioGroup loses its property and all the RadioButtons can be checked at same time.
Any idea how RadioGroup can retain its property using this type of alignment ?

You can Try This....
first declare all radio button
r1=(RadioButton) findViewById(R.id.add_reminder_daily);
r2=(RadioButton) findViewById(R.id.add_reminder_weekly);
r3=(RadioButton) findViewById(R.id.add_reminder_monthly);
r4=(RadioButton) findViewById(R.id.add_reminder_yearly);
now on - onclick listner do
r1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
r2.setChecked(false);
r3.setChecked(false);
r4.setChecked(false);
}
});
r2.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
r1.setChecked(false);
r3.setChecked(false);
r4.setChecked(false);
}
});
r3.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
r2.setChecked(false);
r1.setChecked(false);
r4.setChecked(false);
}
});
r4.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
r2.setChecked(false);
r3.setChecked(false);
r1.setChecked(false);
}
});

try below code works fine at my end:-
<RadioGroup
android:id="#+id/add_reminder_type"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginLeft="10dp"
android:gravity="center_horizontal"
android:orientation="vertical" >
<RadioButton
android:id="#+id/add_reminder_daily"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Daily" />
<RadioButton
android:id="#+id/add_reminder_weekly"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Monthly" />
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"

<RadioButton
android:id="#+id/add_reminder_yearly"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Yearly" />
</LinearLayout>
</RadioGroup>

use this code :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<RadioGroup

How to populate the same view with layout inflater?

I have a layout and every time my button is pressed I want to add a group of views stored in another layout. This is the way I tried it so far. The error in logcat is:
"E/AndroidRuntime(7900): java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first."
Code:
material_cost.xml
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/materialCostText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

android:text="Κόστος Υλικών"
android:textColor="#FF0000"
android:textSize="16sp"
android:textStyle="bold"
android:gravity="center_horizontal"
android:layout_margin="5dp"/>
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:layout_marginBottom="8dp"
android:layout_marginTop="4dp"
android:background="#33B5E5" />
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/materialWrapper">

<LinearLayout

<Button

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Προσθήκη πεδίου"
android:layout_weight="50"/>
</LinearLayout>
</LinearLayout>
</ScrollView>
material_cost_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/materialItem"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:layout_width="50dp"
android:layout_height="wrap_content"

android:text="Υλικό"
android:textSize="16sp"
android:textStyle="italic"
android:layout_weight="50"
android:layout_marginLeft="5dp"/>
<EditText
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="50"
/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:layout_width="50dp"
android:layout_height="wrap_content"
android:id="#+id/materialText"
android:text="Τιμή μονάδας"
android:textSize="16sp"
android:textStyle="italic"
android:layout_weight="50"
android:layout_marginLeft="5dp"/>
<EditText
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="50"
/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:layout_width="50dp"
android:layout_height="wrap_content"
android:id="#+id/materialText"
android:text="Ποσότητα"
android:textSize="16sp"
android:textStyle="italic"
android:layout_weight="50"
android:layout_marginLeft="5dp"/>
<EditText
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="50"
/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:layout_marginBottom="8dp"
android:layout_marginTop="4dp"
android:background="#33B5D8" />
</LinearLayout>
</LinearLayout>
And finally my class:
public class MaterialActivity extends Activity implements OnClickListener {
Button btnAdd;
LinearLayout rootLayout;
View layoutItem;
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.material_cost);
btnAdd = (Button) findViewById(R.id.btnMaterialAdd);
rootLayout = (LinearLayout) findViewById(R.id.materialWrapper);
layoutItem = getLayoutInflater().inflate(R.layout.material_cost_item, rootLayout,false);
rootLayout.addView(layoutItem);
btnAdd.setOnClickListener(this);
}
public void onClick(View v){
switch (v.getId()){
case R.id.btnMaterialAdd:{
inflateEntry();
break;
}
}
}
private void inflateEntry() {
// TODO Auto-generated method stub
Log.v("debug","pressed");
rootLayout.addView(layoutItem);
}
}

you need to inflate the view again every time you click the button:
private void inflateEntry()
{
// TODO Auto-generated method stub
Log.v("debug","pressed");
View layoutItem = getLayoutInflater().inflate(R.layout.material_cost_item, null);
rootLayout.addView(layoutItem);
}

Android Application force closes. (NullPointerException / ToggleButton)

My Code:
public class My_Application extends Activity {
public ToggleButton privBtn = (ToggleButton) findViewById(R.id.privacyShow);
public LinearLayout privLay = (LinearLayout) findViewById(R.id.privacyLayout);
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
privBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(privBtn.isChecked()) {
privLay.setVisibility(LinearLayout.VISIBLE);
}
else {
privLay.setVisibility(LinearLayout.INVISIBLE);
}
}
});
}
}
When I launch the application it force closes. I debugged the application with the built-in Dev Tools application in the emulator, and see the following:
[2011-06-23 20:27:06 - ddms]null

You can't set the privBtn and privLay before the setContentView() is called. Move those two statements into your onCreate().
public class My_Application extends Activity {
public ToggleButton privBtn;
public LinearLayout privLay;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
privBtn = (ToggleButton) findViewById(R.id.privacyShow);
privLay = (LinearLayout) findViewById(R.id.privacyLayout);
privBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(privBtn.isChecked()) {
privLay.setVisibility(LinearLayout.VISIBLE);
}
else {
privLay.setVisibility(LinearLayout.INVISIBLE);
}
}
});
}
}

Click on first not working in android code - android

Try with equalsIgnoreCase Like this to be more precise if (btn.getText().toString().equalsIgnoreCase("More")) {...}

Change this: if (btn.getText()=="More") {...} to this: if (btn.getText().toString().equals("More")) {...}
