In my TopRated.java file, I have an image view which changes when the seekbar is used. It also changes when the next and previous buttons are used. however, i want both buttons and the seeker to be in sync, that is, when the next button is pressed, i want it to also move the seeker up by one, and when the previous button is pressed, i want it to also move the seeker down by one.
please help

i've been trying to make an app with a buttonbar with add/exit buttons at the bottom, and a EditText at the top.
when i hit the add button i want the app to add checkboxes with the text from the EditText.
but when i try to launch the app it force closes.
the logcat show absolutely nothing from my app,
the console says:

I have a fragment defined in my project plus an activity with a button. What I want is to launch the fragment with that button onclick listener, enter a value in the edit text defined in the fragment's xml layout file and press another button2 present in the fragment. Now what I want is that the button2 return's the text value and open's the activity again. I can then handle what happens to that value.

It sound like what you need is a Dialog. Have a look at the development site: http://developer.android.com/guide/topics/ui/dialogs.html
// Use the Builder class for convenient dialog construction
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage(R.string.dialog_fire_missiles)
.setPositiveButton(R.string.fire, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// FIRE ZE MISSILES!
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog
}
});
// Create the AlertDialog object and return it
return builder.create();
Hi I need a soft keyboard with only numeric values 0 to 9 and Enter key. Shouldn't show anything other than these like . , ( ) etc...
I tried several options as suggested here but nothings seems to work for me.
setRawInputType(Configuration.KEYBOARD_QWERTY)
setRawInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_SIGNED)
setRawInputType(InputType.TYPE_CLASS_NUMBER)
setRawInputType(InputType.TYPE_CLASS_PHONE)
I always have the extra characters show up on the keyboard like:
setRawInputType(Configuration.KEYBOARD_12KEY) shows a keyboard like this:
Would appreciate any help. Thanks in advance.
NOTE:
android:minSdkVersion="14": ICS4.0
android:targetSdkVersion="17": JB 4.2
All you can do for standard keyboards is suggest input types. The keyboard can still display or not display whatever keys it wants. If you must have certain keys and only those, you need to create a custom soft keyboard. If it's only for your app, and especially if it's only for one activity, I wouldn't actually implement a standard keyboard, but just use views/buttons that do the appropriate actions.
I've faced the same problem , and i found tat there is no android keyboard like this available
and that the only way is to implement your own.
so i would like to share with you my implement and hopefully save you some valuable time:
i've created this xml , you can modify the colors,fonts and the size of the keyboard accourding to your needs:

3.the effect of a poping keyboard under the EditText when it is pressed is achived by
creating an empty RelativeLayout that function as an container to the keyboard:
<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"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<com.galrom.keyboard.EditTextNoKeyBoard
android:id="#+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/Key_board_container"
android:layout_centerHorizontal="true"
android:clickable="true"
android:ems="10" />
<RelativeLayout
android:id="#+id/Key_board_container"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="38dp"
android:background="#ffffff" >
</RelativeLayout>
when the user press on the EditText the we add the fragment to the container and when he presses done we hide it. the keyboard fragment comunicate with the Activity with the onKeyBoardEvent interace.
NOTE:the hosting activity must implement this interface or else a ClassCastException will be thown.
VERY IMPORTANT: i didn't handled the orientation change, if you change to ladscape while the keyboard is open it will crash, so either disable landscape mode or handle the orientation change to avoid a nullPointerException on the key_board_fragment.
this is the Activity that implemets the keyBoard:

getSupportFragmentManager().beginTransaction().remove(keyboard_fragment).commit();
else
super.onBackPressed();
}
else
super.onBackPressed();
}
}
and the last thing:
to disable the poping of the standart keyboard of android i've created an CustomEditText that simply returns false at: onCheckIsTextEditor() , this is the CustomEditText class:
package com.galrom.keyboard;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.EditText;
public class EditTextNoKeyBoard extends EditText {
public EditTextNoKeyBoard(Context context) {
super(context);
}
public EditTextNoKeyBoard(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public EditTextNoKeyBoard(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
public boolean onCheckIsTextEditor() {
// TODO Auto-generated method stub
return false;
}
}
Hope it helped you out...
if you have suggestions for improvement i will be happy to hear.

In addition to it set inputType="phone" on the EditText. That will open numeric pad keyboard once you start typing however it will include all extra characters related to the numbers. You would need to implement your own keyboard to keep only the numeric values.
This solution uses numberPassword by overriding the default transformation method for the EditText to show characters instead of dots.
<EditText
android:id="#+id/userid"
android:inputType="numberPassword"
android:maxLength="6"
/>
Add to OnCreate.
// Numeric 6 character user id
EditText input = findViewById(R.id.userid);
// Process input and show characters instead of dots
input.setTransformationMethod(SingleLineTransformationMethod.getInstance());
By default based on your device, the keyboard shows the special characters too in number keyboard . specifying the Keyboard type for the Text field you can achieve the expected result,such as
InputFieldName.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD);
i.e.
If you need only number included with special characters,then you can use
InputType.TYPE_CLASS_NUMBER
or
if you need to exclude those special characters too then use InputType.TYPE_NUMBER_VARIATION_PASSWORD
i have had the same problem that you have, and just came with a solution, perhaps its not elegant, nor its easy, but it does work splendid...
First of all, the only InputType that works with that keyboard (at least until 4.3) is "numberPassword", but this "hides" your input as dots. so i used that input with this transformation method:
private class ShowNumbersTransformationMethod implements TransformationMethod {
public CharSequence getTransformation(final CharSequence charSequence, final View view) {
return new PassCharSequence(charSequence);
}
#Override
public void onFocusChanged(final View view, final CharSequence charSequence, final boolean b, final int i,
final Rect rect) {
//nothing to do here
}
private class PassCharSequence implements CharSequence {
private final CharSequence charSequence;
public PassCharSequence(final CharSequence charSequence) {
this.charSequence = charSequence;
}
#Override
public char charAt(final int index) {
return charSequence.charAt(index);
}
#Override
public int length() {
return charSequence.length();
}
#Override
public CharSequence subSequence(final int start, final int end) {
return new PassCharSequence(charSequence.subSequence(start, end));
}
}
}
and then set it to your edittext:
edittext.setTransformationMethod(new ShowNumbersTransformationMethod());
Now, as said before, this is not the happiest solution, but i assure you it works like a charm. It would be 10 times easier to create your own custom keyboard, but, i didnt have that option, since my client wanted the standard keyboard, god knows why...
Hope it helped!
The keyboard itself chooses what keys to layout. The best you can do is specify InputType.TYPE_CLASS_NUMBER, but the keyboard will still display whatever it thinks is appropriate to a numeric text field.
I created a custom dialog with spinner and OK button. I have populated this spinner with some items and inflated the layout.If I click OK button dialog will dismiss.
I set the spinner
spinner.performCLick();
is there is any way to get spinner selected item and to close the dialog without pressing OK button. I have tried
button.performclick();
but no use.
see my below code it may help you.
package com.Test_dia;
import android.app.Activity;
import android.app.Dialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.Spinner;
import android.widget.Toast;
public class Test_diaActivity extends Activity {
private Button btn;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btn = (Button) findViewById(R.id.button1);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
showalert();
}
});
}
protected void showalert() {
// TODO Auto-generated method stub
final Dialog dia = new Dialog(this);
dia.setContentView(R.layout.dia);
final String a[] = { "select one", "android", "java", "php" };
Button btnok = (Button) dia.findViewById(R.id.button2);
Spinner spin = (Spinner) dia.findViewById(R.id.spinner1);
btnok.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
dia.dismiss();
}
});
spin.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, a));
spin.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
if (arg2 > 0) {
Toast.makeText(Test_diaActivity.this,
"You Selected :" + a[arg2], Toast.LENGTH_SHORT)
.show();
dia.dismiss();
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
dia.show();
}
}
main.xml
<LinearLayout
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="click here" />
</LinearLayout>
dia.xml
<Spinner
android:id="#+id/spinner1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginTop="16dp" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/spinner1"
android:text="ok" />
This code is work for me perfectly ok.
enjoy....
EDIT (removed previous non-suitable answer)
I'm going to assume that your issue is that using setOnItemSelectedListener is firing 'onItemSelected' on startup (thus selecting the first item in the spinner without any user input) and you don't want that.
If that is the case, try the following.
Set a class variable:
private int newSpinner = 0;
Then in the setOnItemSelectedListener:
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
#Override
public void onItemSelected(AdapterView<?> parent, View view,int pos, long id) {
if (newSpinner != 0) {
// Do your code thing here
dismiss();
} else {
newSpinner++
}
}
});
