Android: TextView alignment with respect to RadioGroup

Android: TextView alignment with respect to RadioGroup - android

Hi i'm trying to implement the following design (RadioGroup is parallel to TextView of rignt side)
for this requirement i wrote the bellow xml code
<RelativeLayout
android:id="#+id/rl_group_create_group_privacy"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/rl_group_create_group_icon"
android:layout_marginTop="10dp"
android:background="#drawable/rl_bg_board_group_create_group"
android:padding="10dp" >
<TextView
android:id="#+id/tv_group_create_group_privacy"
android:layout_width="60dp"
android:layout_height="wrap_content"
android:text="#string/group_create_new_group_privacy"
android:textColor="#color/Black"
android:textSize="15sp" />
<RadioGroup
android:id="#+id/rg_group_create_group_privacy"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/tv_group_create_group_privacy"
android:orientation="vertical" >
<RadioButton
android:id="#+id/rb_group_create_group_public"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:checked="false"
android:text="#string/group_create_new_group_public"
android:textSize="12sp" />
<RadioButton
android:id="#+id/rb_group_create_group_closed"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:layout_weight="1"
android:checked="false"
android:text="#string/group_create_new_group_closed"
android:textSize="12sp" />
<RadioButton
android:id="#+id/rb_group_create_group_secret"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="19dp"
android:layout_weight="1"
android:checked="false"
android:text="#string/group_create_new_group_secret"
android:textSize="12sp" />
</RadioGroup>
<RelativeLayout
android:id="#+id/rl_group_create_group_privacy_desc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_toRightOf="#+id/rg_group_create_group_privacy"
android:background="#color/White" >
<TextView
android:id="#+id/tv_group_create_group_public_desc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:text="#string/group_create_new_group_public_desc"
android:textColor="#color/Black"
android:textSize="12sp" />
<TextView
android:id="#+id/tv_group_create_group_closed_desc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/tv_group_create_group_public_desc"
android:layout_marginTop="10dp"
android:text="#string/group_create_new_group_closed_desc"
android:textColor="#color/Black"
android:textSize="12sp" />
<TextView
android:id="#+id/tv_group_create_group_secret_desc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/tv_group_create_group_closed_desc"
android:layout_marginTop="10dp"
android:text="#string/group_create_new_group_secret_desc"
android:textColor="#color/Black"
android:textSize="12sp" />
</RelativeLayout>
</RelativeLayout>
But it changing the alignment according to the device like the following picture (Some times radio button at middle of textView and some times at starting of textView and some more times at end of textView). By implementing the design in layout-large, layout-small, layout-xlarge we can achieve this some how but i don't want to follow. So, how to implement first image design without following layout-large, layout-small, layout-xlarge

I hope this may helpful to you

No Action onRadioButton click after reset

I'm an Android beginner and I have a little problem.
I have 2 radioButtons titled "Yes" and "No", 4 editTexts which are disabled and a button titled "Reset All".
Now, when I select the "No" radioButton, editTexts 1 and 2 become enabled and 1 gains focus. This is the desired behaviour. But When I select "Reset All" and again repeat the procedure, only editText 2 gets enabled and the "No" radioButton is still unchecked.
Following is my code:
MainActivity.java
package com.example.chris.myapplication;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.RadioButton;
public class MainActivity extends AppCompatActivity {
EditText e1;
EditText e2;
EditText e3;
EditText e4;
RadioButton yes;
RadioButton no;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
e1 = (EditText)findViewById(R.id.e1);
e2 = (EditText)findViewById(R.id.e2);
e3 = (EditText)findViewById(R.id.e3);
e4 = (EditText)findViewById(R.id.e4);
yes = (RadioButton)findViewById(R.id.yes);
no = (RadioButton)findViewById(R.id.no);
}
public void onClickreset(View v){
yes.setChecked(false);
no.setChecked(false);
e1.setEnabled(false);
e2.setEnabled(false);
e3.setEnabled(false);
e1.setText("");
e2.setText("");
e3.setText("");
e4.setText("");
};
public void onRadioButtonClicked(View v)
{
boolean checked = ((RadioButton) v).isChecked();
switch(v.getId()){
case R.id.yes:
if(checked)
e1.setEnabled(false);
e2.setEnabled(false);
e3.setEnabled(true);
e3.requestFocus();
break;
case R.id.no:
if(checked)
e1.setEnabled(true);
e2.setEnabled(true);
e2.requestFocus();
e2.clearFocus();
e3.setEnabled(false);
break;
}
}
}

It's better to use RadioGroup.OnCheckedChangeListener, first of all, get rid of android:onClick attributes and assign an id to RadioGroup in XML:
<RadioGroup
android:id="#+id/yes_no_radio_group"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_span="3"
android:gravity="center"
android:orientation="horizontal">
<RadioButton
android:id="#+id/yes"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="1dp"
android:checked="false"
android:text="yes" />
<RadioButton
android:id="#+id/no"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="4dp"
android:checked="false"
android:text="no" />
</RadioGroup>
Then make your Activity implements RadioGroup.OnCheckedChangeListener and move there code from onRadioButtonClicked(View v) method:
public class MainActivity extends AppCompatActivity implements RadioGroup.OnCheckedChangeListener {
//Some activity code
#Override
public void onCheckedChanged(RadioGroup radioGroup, int i) {
switch (radioGroup.getCheckedRadioButtonId()) {
case R.id.yes: //Not needed to
e1.setEnabled(false); //which RadioButton clicked
e2.setEnabled(false);
e3.setEnabled(true);
e3.requestFocus();
break;
case R.id.no:
e1.setEnabled(true);
e2.setEnabled(true);
e2.requestFocus();
e2.clearFocus();
e3.setEnabled(false);
break;
}
}
}
Then, assign OnCheckedChangeListener with RadioGroup:
yesNoGroup = findViewById(R.id.radio_group);
yesNoGroup.setOnCheckedChangeListener(this);
And change:
yes.setChecked(false);
no.setChecked(false);
To
yesNoGroup.clearCheck();

EditText OnFocusChangeListener() doesn't hide cursor and view

I made an EditText OnFocusChangeListener that supposedly hides the cursor and another view when it's not in focus (i.e. clicking anywhere on the screen aside from the EditText will hide those items). Clicking on the EditText is the only time that will display them.
This is my OnFocusChangeListener for my EditText pageTitle:
pageTitle.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean b) {
if(b) {
pageTitle.setCursorVisible(true);
saveCancelBar.setVisibility(View.VISIBLE);
} else {
pageTitle.setCursorVisible(false);
saveCancelBar.setVisibility(View.GONE);
}
}
});
I also made an OnclickListener:
pageTitle.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
pageTitle.setCursorVisible(true);
saveCancelBar.setVisibility(View.VISIBLE);
}
});
The OnClickListener works but not the OnFocusListener. Ideally, pageTitle's cursor and saveCancelBar are initially hidden and will only appear when pageTitle is clicked.

If you check the definition of onFocusChange(View v, boolean hasFocus) you will notice that your code must change like this:
pageTitle.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean hasFocus) {
if(!hasFocus) {
pageTitle.setCursorVisible(true);
saveCancelBar.setVisibility(View.VISIBLE);
} else {
pageTitle.setCursorVisible(false);
saveCancelBar.setVisibility(View.GONE);
}
}
});
This is the code for checking the soft keyboard visibility in Android
public class MainActivity extends AppCompatActivity
{
public static String TAG = MainActivity.class.getSimpleName();
private TextView saveCancelBar;
private EditText pageTitle;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setListenerToRootView();
saveCancelBar = (TextView) findViewById(R.id.cancel_bar);
pageTitle = (EditText) findViewById(R.id.title);
pageTitle.setOnFocusChangeListener(new View.OnFocusChangeListener()
{
#Override
public void onFocusChange(View view, boolean hasFocus)
{
...
}
});
}
public void setListenerToRootView()
{
final View activityRootView = getWindow().getDecorView().findViewById(android.R.id.content);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener()
{
#Override
public void onGlobalLayout()
{
Rect r = new Rect();
activityRootView.getWindowVisibleDisplayFrame(r);
int screenHeight = activityRootView.getRootView().getHeight();
// r.bottom is the position above soft keypad or device button.
// if keypad is shown, the r.bottom is smaller than that before.
int keypadHeight = screenHeight - r.bottom;
Log.e(TAG, "keypadHeight = " + keypadHeight);
if (keypadHeight > screenHeight * 0.15) {
// 0.15 ratio is perhaps enough to determine keypad height.
Toast.makeText(getApplicationContext(), "Gotcha!!! softKeyboard open", Toast.LENGTH_SHORT).show();
} else {
// keyboard is closed
Toast.makeText(getApplicationContext(), "Gotcha!!! softKeyboard closed", Toast.LENGTH_SHORT).show();
saveCancelBar.setVisibility(View.GONE);
}
}
});
}
}

I think you forgot to add focusableInTouchMode. Add focusableInTouchMode to your editText to get focused on touching the view.
android:focusableInTouchMode="true"

Hello I am developing an application android, I have a problem with a text view that retrieves the data via web service, the data retrieve appears but infringe on the other text view of the page, Here is my code from my xml page:

Then my code that says or go data :
public class DetailEtab extends Activity {
private TextView tv;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.etabdetail);
tv = (TextView) findViewById(R.id.tvl);
tv.setText(search_ville.etabSELECT.getLibelle());
tv = (TextView) findViewById(R.id.tvcp);
tv.setText(search_ville.etabSELECT.getCp());
tv = (TextView) findViewById(R.id.tvv);
tv.setText(search_ville.etabSELECT.getVille());
tv = (TextView) findViewById(R.id.tvp);
tv.setText(search_ville.etabSELECT.getPresentation());
Button btnSa = (Button) findViewById(R.id.btnMa);
btnSa.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(DetailEtab.this, MaterielAssocie.class);
startActivity(intent);
Log.i("ETAB", "servcies associes");
Toast toast = Toast.makeText(getApplicationContext(), "services associes", Toast.LENGTH_SHORT);
toast.show();
}
});
}
}
If anyone can tell me why it does that thanks

You have problems with your layouts. I recommend you to wrap every line into separate LinearLayout and then use LinearLayout to wrap all new LinearLayouts. Also due to long text it's better to wrap parent LinearLayout into Scroll.
NOTE: This is just example that was written inside text box that simply shows main idea and may contain mistakes
Something like this:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/tvd"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Détail de l'établissement"
android:textSize="20dp"
android:textStyle="bold"/>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/textView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="42dp"
android:text="Libelle :"
android:textSize="20dp"
android:textStyle="bold"
/>
<TextView
android:id="#+id/tvl"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="libelle"
android:textSize="20dp"
/>
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/textView4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="64dp"
android:text="Code postal :"
android:textSize="20dp"
android:textStyle="bold" />
<TextView

You are assigning tv to multiple different TextViews and then you are assigning multiple values to the last TextView you assign it to.

public class DetailEtab extends Activity {
private TextView tv,tv1,tv2,tv3;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.etabdetail);
tv = (TextView) findViewById(R.id.tvl);
tv.setText(search_ville.etabSELECT.getLibelle());
tv1 = (TextView) findViewById(R.id.tvcp);
tv1.setText(search_ville.etabSELECT.getCp());
tv2 = (TextView) findViewById(R.id.tvv);
tv2.setText(search_ville.etabSELECT.getVille());
tv3 = (TextView) findViewById(R.id.tvp);
tv3.setText(search_ville.etabSELECT.getPresentation());
Button btnSa = (Button) findViewById(R.id.btnMa);
btnSa.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(DetailEtab.this, MaterielAssocie.class);
startActivity(intent);
Log.i("ETAB", "servcies associes");
Toast toast = Toast.makeText(getApplicationContext(), "services associes", Toast.LENGTH_SHORT);
toast.show();
}
});
}
}

NullPointerException in dialog - Strange case

I have a stupid problem but i couldnt solve it yet. I have an activity with a button in toolbar, this button open one dialog with some filter params.
Here is what a i did..
Spinner spinner_categoria;
Spinner spinner_vendedor;
SeekBar seek_preco;
TextView tv_filtro;
onCreate method {
...
}

spinner_vendedor.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, listVendedor));
String oi = "oi";
tv_filtro.setText(oi);
dialog.setContentView(dialogView);
dialog.show();
seek_preco.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {

EDIT: I know what is a NullPointerException, I already checked the previous posts on the subject, but no problem is the same as mine

I think the problem is with findViewByID. The documentation says
findViewById
Added in API level 1
View findViewById (int id)
Finds a child view with the given identifier. Returns null if the specified child view does not exist or the dialog has not yet been fully created (for example, via show() or create()).
It is just possible that since you are calling show() later the textView might not be created. I would do this
View dialogView = LayoutInflater.from(context).inflate(R.layout.dialog_filtro, null);
Button bt_cancelar = (Button) dialogView.findViewById(R.id.cb_filtro_cancelar);
Button bt_aceitar = (Button) dialogView.findViewById(R.id.cb_filtro_aceitar);
seek_preco = (SeekBar) dialogView.findViewById(R.id.sb_preco_max);
tv_filtro = (TextView) dialogView.findViewById(R.id.tv_filtro_preco);
spinner_categoria = (Spinner) dialogView.findViewById(R.id.spinner_categoria);
spinner_vendedor = (Spinner) dialogView.findViewById(R.id.spinner_vendedor);
dialog.setContentView(dialogView)
dialog.show();
spinner_categoria.setAdapter(ArrayAdapter.createFromResource(
this, R.array.categoria_array, android.R.layout.simple_spinner_item));
spinner_vendedor.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,listVendedor));
tv_filtro.setText("oi");

Thanks for everyone that tried to help.

Adding RadioButtons in Android

I want to add radio buttons such that only one of them is selected at a time among 4 buttons and I want to place them as:
RadioButton1 RadioButton2
RadioButton3 RadioButton4
I am trying the following code but 1&2 forms a grp and 3&4 forms a different grp and there are two value selected a time. Can anyone check it and share the correct way to do it?
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/apple" />
<LinearLayout
android:layout_width="wrap_content"

Ok I find a solution for you:
I know it is not the best solution but it works! :)
Just copy the xml file and activity code bellow:
Activity:
package com.example.stackoverflow;
import android.os.Bundle;
import android.app.Activity;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.RadioButton;
public class MainActivity extends Activity {
private static String TAG = "MainActivity";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final RadioButton radiobutton1 = (RadioButton) findViewById(R.id.RadioButton1);
final RadioButton radiobutton2 = (RadioButton) findViewById(R.id.RadioButton2);
final RadioButton radiobutton3 = (RadioButton) findViewById(R.id.RadioButton3);
final RadioButton radiobutton4 = (RadioButton) findViewById(R.id.RadioButton4);
radiobutton1.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
radiobutton1.setChecked(true);
radiobutton2.setChecked(false);
radiobutton3.setChecked(false);
radiobutton4.setChecked(false);
return true;
}
});
radiobutton2.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
radiobutton2.setChecked(true);
radiobutton1.setChecked(false);
radiobutton3.setChecked(false);
radiobutton4.setChecked(false);
return true;
}
});
radiobutton3.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
radiobutton3.setChecked(true);
radiobutton1.setChecked(false);
radiobutton2.setChecked(false);
radiobutton4.setChecked(false);
return true;
}
});
radiobutton4.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
radiobutton4.setChecked(true);
radiobutton1.setChecked(false);
radiobutton2.setChecked(false);
radiobutton3.setChecked(false);
return true;
}
});
}
}
activity_main.xml :
<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" >
<TableLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:background="#FFDDDDDD" >
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<RadioGroup
android:id="#+id/rdogrp1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<RadioButton
android:id="#+id/RadioButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Orange"
android:textColor="#000000" />
<RadioButton
android:id="#+id/RadioButton2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="50dp"
android:text="BlueBerry"
android:textColor="#000000" />
</RadioGroup>
</TableRow>
<TableRow
android:id="#+id/tableRow2"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<RadioGroup
android:id="#+id/rdogrp2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<RadioButton
android:id="#+id/RadioButton3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Apple "
android:textColor="#000000" />
<RadioButton
android:id="#+id/RadioButton4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="50dp"
android:text="Santra :P"
android:textColor="#000000" />
</RadioGroup>
</TableRow>
</TableLayout>
</RelativeLayout>

For that you need to create only one RadioGroup and add four different RadioButton.
And for adding UI refer this url : Manage Layout Inside a Horizontal Oriented Radiogroup .
I hope this will help you.

Try Like this..
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RadioGroup
android:id="#+id/rdogrp_main"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<RadioButton
android:id="#+id/RadioButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.20"
android:text="India"
android:textColor="#000000" />
<RadioButton
android:id="#+id/RadioButton2"
android:layout_width="74dp"
android:layout_height="wrap_content"
android:layout_weight="0.57"
android:text="Austraila"
android:textColor="#000000" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<RadioButton
android:id="#+id/RadioButton3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.25"
android:text="Srilanka "
android:textColor="#000000" />
<RadioButton
android:id="#+id/RadioButton4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.48"
android:text="SouthAfrica"
android:textColor="#000000" />
</LinearLayout>
</RadioGroup>
</LinearLayout>
Let me know if you solve the problem...
