i'm doing a cable length calculator, and i'm having trouble with negative numbers.
EditTexts are like this
<EditText android:layout_height="wrap_content" android:layout_weight="1" android:inputType="numberDecimal|numberSigned" android:layout_width="40px" android:id="#+id/rxmax">
</EditText>
Then i use them like this:
final EditText rxmax = (EditText) findViewById(R.id.rxmax);
double RXmax = new Double(rxmax.getText().toString());
After i do a simple calculation:
double OPBmax = TXmax - RXmax;
Somewhere the inputted negative number turns positive. i'm guessing at the toString conversation but i don't find anything on how to prevent this.
Use
android:digits="0123456789"
EX:
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:digits="0123456789"
android:gravity="center"
android:inputType="numberSigned"
android:textColor="#color/black"
android:textSize="#dimen/font_size_small" />
I've tried this, and it works...
Activity:
double RXmax;
EditText rxmax;
TextView tv;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
rxmax = (EditText) findViewById(R.id.rxmax);
tv = (TextView) findViewById(R.id.text);
}
public void click(View v) {
RXmax = new Double(rxmax.getText().toString());
tv.setText(Double.toString(RXmax));
}

<Button android:layout_height="wrap_content" android:id="#+id/button1"
android:layout_weight="1" android:text="Button" android:layout_width="wrap_content"
android:onClick="click"></Button>
</LinearLayout>
If I type -2, after clicking the TextView displays -2.0
If you're using Eclipse, try Project --> Clean..., and select your project. Maybe this will help.

I have an OnClickListener that listens to Button A clicks. I also have 2 TextViews below the Button.
I want that on every click on Button A, the 2 TextViews will switch their places between them, like this:
Before clicking:
TextView A
TextView B
After clicking:
TextView B
TextView A
How can I do it? Is there a special function that meant to do that? or some kind of a trick? Thanks!

}
View.bringToFront method may be useful.
Where your layout is like:
<LinearLayout>
<TextView A>
<TextView B>
</LinearLayout>
To call bringToFront on TextView A will bring it front (the last position in the parent LinearLayout).
<LinearLayout>
<TextView B>
<TextView A>
</LinearLayout>
For more detailed example, below is layout.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/text_holder"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">
<TextView
android:id="#+id/text_a"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/text_a" />
<TextView
android:id="#+id/text_b"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/text_b" />
</LinearLayout>
In your OnClickListener (in your Activity) call:
View textViewA = findViewById(R.id.text_a);
textViewA.bringToFront();
This should work.
Toggling behavior can be achieved by this application. For example:
ViewGroup textHolder = (ViewGroup) findViewById(R.id.text_holder);
textHolder.getChildAt(0).bringToFront();
ViewGroup.getChildAt(0) always returns the first child of the ViewGroup. So everytime you call bringToFront on the first child will be bring to front.
All previous answers do not work because you use a relative layout where a linear layout will suffice.
If you have to go RelativeLayout, do the following in your click listener
TextView textA = (TextView) findViewById(R.id.txtA);
TextView textB = (TextView) findViewById(R.id.txtB);
RelativeLayout.LayoutParams textALayoutParams = (RelativeLayout.LayoutParams) textA.getLayoutParams();
textALayoutParams.addRule(RelativeLayout.BELOW, R.id.txtB);
textA.setLayoutParams(textALayoutParams);
RelativeLayout.LayoutParams textBLayoutParams = (RelativeLayout.LayoutParams) textB.getLayoutParams();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
textBLayoutParams.removeRule(RelativeLayout.BELOW);
} else {
textBLayoutParams.addRule(RelativeLayout.BELOW,0);
}
textB.setLayoutParams(textBLayoutParams);
This will place A under B. You can do the same for reversing.
For example. There is picture on the top of the screen below that there are some empty boxes and below the boxes there are some buttons. Every button has a character for text("a","c","t"). You click on a button and the button's text appear in the box. You can click them in the order you want to but the answer is "cat" so when you put the characters in the correct order then you got a toast.
I tried to do it with TextViews and Buttons. I can make the button disappear when i click on it and a textview appear in the same time. But every textview has a fix place on the screen, so i need to put every character in every box invisible and when i click on the "c" character it appear in the first box and the other "c" characters stay invisible. But if i click on the "a" first, then it appears in the second box because there is too much variation to do all. I'm not good at explaining but if anyone has an idea how to do that easier please response!

You might want to try a slightly different approach.
If I understand you correctly, you want to "type" a word out using given lettered buttons. Like one of those hangman style games.
Why not append the text views on the fly.
Something like
#Override
public void onClick(View v) {
//Grab the surrounding layout for the textviews
GridView answerGrid = (GridView)getViewById(R.id.answerGrid);
//Get the text that was on the button
Button b = (Button)v;
String btnText = b.getText().toString();
//Make a text view with text
TextView txt = new TextView();
text.setText(btnText);
//Append to text view container
answerGrid.addView(txt);
//Invisible button
b.setVisibility(View.INVISIBLE);
}
Haven't tested to see if this is perfect, but its a start.
=====
I've looked at your xml
Why not use GridViews?
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
....>
<GridView android:id="#+id/answerGrid"
....>
<!-- Put nothing here. This is for answers -->
</GridView>
<GridView android:id="#+id/lettersGrid"
android:layout_below="answerGrid"
....>
<!-- Buttons in here -->
</GridView>
</RelativeLayout>
This way you can customise the number of rows/columns based on the length of the word you're playing with. And GridView will automatically give you a neat layout and spacing.
Have a look at the GridView doc and get it customised the way you want it.
See my edits above for the Java code.
I am new to java and android so please forgive me if i am asking to simple question.
I have an application which requires user input in two EditTexts. Those inputs are multipied and result is displayed in TextView. I would like to use "clear entries" button which would clear the content of user entries and displayed result. Is there any way to do it?
Here is an application code.
package c.example.rectangle;
import android.os.Bundle;
import android.view.View;
import android.app.Activity;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends Activity implements OnClickListener{
EditText l;
EditText w;
TextView a;
Button b;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
l = (EditText) findViewById(R.id.length);
w = (EditText) findViewById(R.id.width);
a = (TextView) findViewById(R.id.lblarea);
b = (Button) findViewById(R.id.calculate);
b.setOnClickListener(this);
}
public void onClick(View v) {
calculateRectangle(l.getText().toString(), w.getText().toString());
}
private void calculateRectangle(String clength, String cwidth){
double area = Double.parseDouble(clength)*Double.parseDouble(cwidth);
a.setText(String.valueOf(area));
}}

I would be very appreciate for the answer.
Why not just set both editTexts to empty when you no longer need the data in them to be displayed?
EditText.setText("");
Same thing with the TextView;
TextView.setText("");
If you are wanting to iterate through them, you can put them in a list then use a for loop to set the text to ""
List<EditText> myList = new List<EditText>();
myList.add(editText1);
Then in your clear method
for (int x = 0; x < myList.size(); x++
{
myList.get(x).setText("");
}
Why nobody seems to use the really useful android:onClick ?
<Button
...
android:text="#string/calculate"
android:onClick="calculate" />
<Button
...
android:text="#string/clear"
android:onClick="clearForm" />
With the following activity :
class MyActivity extends Activity
{
...
/**
* Calculate
* android:onClick="calculate"
*/
public void calculate(View view)
{
// Handle click on your 'Calculate' button
}
/**
* Clear form
* android:onClick="clearForm"
*/
public void clearForm(View view)
{
int[] ids = new int[]{R.id.length, R.id.width};
for(int id : ids)
{
((EditText) this.findViewById(id).)setText("");
}
}
}
This way, you do not have to care about ids and your code will be more clean than clean.
Ids should not be overused! They are great on views that can be 'changed' by the user to handle those changes (and to enjoy the onSaveInstanceState() natural behavior) but that's it!
IMO.
If you want to create a clear button, do the following.
Create a Button in your xml:
<Button
android:id="#+id/clear_button"
... you own layout prefs ...
/>
Create a listener for the button in your code:
OnClickListener clearButtonListener = new OnClickListener(){
#Override
public void onClick(View view) {
((EditText)findViewById(R.id.id_for_text_box_a)).setText("");
//...do this for all your edit texts that you want to clear
}
};
Connect the listener to the button
Button clearButton = (Button) findViewById(R.id.clear_button);
clearButton.setOnClickListener(clearButtonListener);
Alternatively, instead of finding the edit texts by id in the listener, they could be instance variables that get initialized in onCreate or wherever. I would also recommend not using one letter variable names.
Personally, I would set OnClickListeners instead of the onClick attribute in the XML. Although using the XML onClick attribute may amount to fewer lines of code, it unfortunately creates a very tight coupling of layout and functionality. I prefer to have XML for layout, and Java for functionality. Additionally, being forced to use ids amounts to requiring XML elements to have variable names, which makes for more readable layout code (what is this button? what is this checkbox for?). Another problem I see with using the onClick attribute is that it forces your methods called to be public, which doesn't really make sense for many of these methods. I prefer to understand what an Activity does functionally through reading the Java, and I would rather not have unreferenced public methods floating around in my Activities.
I am trying to add an edit text view dynamically to a layout from the java class. However from what I have implemented nothing changes on my action. This is what I have:
public final void onCreate(final Bundle i){
int value = 0;
isEdit = false;
try
{
super.onCreate(i);
this.setContentView(R.layout.contactedit);
ContactList.soundIndicator = 0;
etPhoneNumber = new ArrayList<EditText>();
this.etPhoneNumber.add((EditText) this.findViewById(R.id.etPhoneNumberInput));
this.addNumberBtn = (Button) this.findViewById(R.id.addNumberEditText);
addNumberBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//etPhoneNumber.add(new EditText(ContactEdit.this));
try{
LinearLayout layout = (LinearLayout) findViewById(R.id.contacteditll);
EditText temp = new EditText(ContactEdit.this);
temp.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
etPhoneNumber.add(temp);
layout.addView(temp);
}catch(Exception e){
Log.d(TAG, "Failed to create new edit text");

Whenever I click on my button the action is heard but nothing is done. The layout of the page does not change even though the new edit text is in my list of edit texts and I am adding the new edit text to the layout.
Any help would be appreciated thanks.
It sure gets added but you are not seeing it cause there is no space left. Two things to test:
Place the LinearLayout inside a ScrollView.
Use the weight parameter.
Using the weight parameter:
EditText temp = new EditText(ContactEdit.this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT, 1);
temp.setLayoutParams(params);
I need to put EditText box with vertical scrollbar on custom dialog.i.e when I entered more than one line on edittext, it should be scrolled. Here I used android: scrollable="vertical" on xml.
It works fine. When I use two edittext boxes, the curor will move to second edittext box when I press enter on first. Any mistakes?
My code...
EditText edit1,edit,edit0;
Button ok;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.main);
final Dialog dialog = new Dialog(summaact.this);
dialog.setContentView(R.layout.main);
edit0=(EditText)dialog.findViewById(R.id.edit0);
edit=(EditText)dialog.findViewById(R.id.edit);
edit1=(EditText)dialog.findViewById(R.id.edit1);
edit0.setInputType(InputType.TYPE_NULL);
edit.setInputType(InputType.TYPE_NULL);
edit1.setInputType(InputType.TYPE_NULL);
ok=(Button)dialog.findViewById(R.id.ok);
dialog.setTitle("Content Management page");
dialog.setCancelable(true);
ok.setOnClickListener(new OnClickListener(){
public void onClick(View v){
String str0=edit0.getText().toString();
String str=edit1.getText().toString();
String str1=edit.getText().toString();
Toast.makeText(summaact.this,str0,Toast.LENGTH_SHORT).show();
Toast.makeText(summaact.this,str,Toast.LENGTH_SHORT).show();
Toast.makeText(summaact.this,str1,Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
});
dialog.show();
}
My xml...
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<EditText
android:id="#+id/edit0"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<EditText
android:id="#+id/edit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<EditText
android:id="#+id/edit1"
android:layout_width="fill_parent"
android:layout_height="100px"
android:scrollbars="vertical"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/ok"
android:text="OK"/>
</LinearLayout>
new answer:
Try using:
android:inputType="textMultiLine"
in EditText
edit:
I made an example and it works with textMultiline:
#Override
protected void onResume() {
super.onResume();
AlertDialog.Builder b = new AlertDialog.Builder(this);
View view = LayoutInflater.from(this).inflate(R.layout.main, null);
b.setView(view);
b.setTitle("Content Management page");
b.create().show();
}
Layout is the same except one EditText:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<EditText
android:id="#+id/edit0"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<EditText
android:id="#+id/edit"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<EditText
android:id="#+id/edit1"
android:layout_width="fill_parent"
android:gravity="top|left"
android:layout_height="100dp"
android:scrollbars="vertical"
android:inputType="textMultiLine" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/ok"
android:text="OK" />
</LinearLayout>
Where did you have problem?
try
YourEditText.setMovementMethod(new ScrollingMovementMethod());
and be sure to set scrollbars true
