show EditText on condition

show EditText on condition - android

Right now I have an idea for a project and I would like to know if anyone can help me on the same logic.
As such I need to create or generate a number of EditText according to amount you enter, ie, to select or enter a number such as 5, show me 5 EditText layout for type 5 values. They know that the form could accomplish this? Any ideas please?
I guess it must be a way to do it with a loop, but not like carrying this calculation Java to XML. Thank you.

Here is an example of generating EditText items based on the number you enter. You can ignore the scrollview in the layout file I just put it in case someone added a lot of EditText items that would go off the screen.

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final EditText count = (EditText) findViewById(R.id.count);
final TextView output = (TextView) findViewById(R.id.output);
final Button generate = (Button) findViewById(R.id.generate);
final Button values = (Button) findViewById(R.id.values);
final LinearLayout container = (LinearLayout) findViewById(R.id.container);
generate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int numberOfControlsToGenerate = 0;
try {
numberOfControlsToGenerate = Integer.parseInt(count.getText().toString().trim());
} catch (NumberFormatException e) {
Log.e(TAG, e.getMessage(), e);
}
if (numberOfControlsToGenerate > 0) {
if (container.getChildCount() > 0) {
container.removeAllViews();
}
for (int counter = 0; counter < numberOfControlsToGenerate; counter++) {
addEditText(container);
}
}
}
});
values.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String[] editTextValues = new String[container.getChildCount()];
StringBuilder editTextValuesBuilder = new StringBuilder();
for (int counter = 0; counter < container.getChildCount(); counter++) {
EditText child = (EditText) container.getChildAt(counter);
editTextValues[counter] = child.getText().toString().trim();
editTextValuesBuilder.append(editTextValues[counter]).append("\n");
}
output.setText(editTextValuesBuilder.toString());
}
});
}
private void addEditText(LinearLayout container) {
final LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
EditText editTextToAdd = new EditText(this);
editTextToAdd.setLayoutParams(params);
container.addView(editTextToAdd);

How to create a view programmatically at 12 AM every day

How would I go about creating a TextView at 12 AM every day, regardless if the app is open or not (unbound to app lifetime)? I already have the code to create the TextView, I just need to know how I would execute the code at 12 AM every day.
I'm not going to be opening another activity, everything will be done within the same activity.
Here is my code and my xml:

You need to schedule a periodic task using Work Manager.
val myUploadWork = PeriodicWorkRequestBuilder<SaveImageToFileWorker>(
24,TimeUnit.HOURS) // The work is scheduled to repeat after 24 hours.
.build()
Then you can submit the request to system :
WorkManager
.getInstance(myContext)
.enqueue(myUploadWork)

How to set a line break after a set of EditText which have been dynamically created?

I am trying to show few EditText field just like n*n Matrix. I am creating these EditText field dynamically.
Problem is all my EditText field prints in the same line horizontally.
I wanted to know is there anything like "System.out.println();" in Android Studio!
Note: I want this line break in between Views, not in between Text, so \n doesn't work here!

Use TableLayout instead of LinearLayout for n*n matrix pattern
for (int i = 0; i < noOfRows; i++) {
TableRow row= new TableRow(this);
TableRow.LayoutParams lp = new
TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT
,TableRow.LayoutParams.WRAP_CONTENT);
row.setLayoutParams(lp);
for(int j = 0; j < noOfColumns; j++) {
EditText et = new EditText(this);
//Extra properties goes here...
et.setText("Your text");
row.addView(et,j);

update your xml file remove onClick from your button
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Add"
android:id="#+id/add"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/sub"
android:id="#+id/sub"
/>
Problem is with your getting value from sharedPreference
String v=sharedPreferences.getInt("value","");
why are you passing string as default value and your
try this String
v = Integer.toString(sharedPreferences.getInt("value",0));

in the layout you´ve got android:onClick="add" there should be a public void add(View v) to handle the event. Do the sum inside that handler.
Please, follow the documentation
http://developer.android.com/reference/android/widget/Button.html and see the :onCLick handling.

How to set a TextView from an ArrayList, character by character, sequentially?

I want to put a text in a TextView sequentially, with a known time between characters, from a written text in an EditText
That is the solution I made:
I wrote two ArrayList charged from an EditText, the first one with Characters from the EditText , the second one with Integers for determine the time between characters.
Then I parse the ArrayLists, times load of the time integers are done sequentially, but not the characters, the TextViews are drawn only when the cycle ends.
My code
The MainActivity:
import java.util.ArrayList;
import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends Activity {
private TextView showCharacter;
private TextView showAppendCharacter;
private EditText incomingText;
private Button readTextEdit;
private ArrayList<CharSequence> toText = new ArrayList<CharSequence>();
private ArrayList<Integer> timePlay = new ArrayList<Integer>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
showCharacter = (TextView) findViewById(R.id.showCharacterTextView);
showAppendCharacter = (TextView) findViewById(R.id.showAppendCharacterTextView);
incomingText = (EditText) findViewById(R.id.incomingEditText);
readTextEdit = (Button) findViewById(R.id.readTextButton);
readTextEdit.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
toText.clear();
timePlay.clear();
showAppendCharacter.setText("");
String text = incomingText.getText().toString();
for (int base = 0; base < text.length(); base++) {
if (String.valueOf(text.charAt(base)).equals("a")) {
toText.add(("a"));
timePlay.add(500);
} else if (String.valueOf(text.charAt(base)).equals("b")) {
toText.add(("b"));
timePlay.add(650);
} else if (String.valueOf(text.charAt(base)).equals("c")) {
toText.add(("c"));
timePlay.add(800);
} else {
toText.add(("_"));
timePlay.add(1000);
}
}
for (int pos = 0; pos < toText.size(); pos++) {
try {
Thread.sleep(timePlay.get(pos));
showCharacter.setText((String) toText.get(pos));
showAppendCharacter.append((String) toText.get(pos));
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
});
}
}
The activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"

<TextView

<requestFocus />
</EditText>
<Button
android:id="#+id/readTextButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/readButton" />
The strings.xml:
<?xml version="1.0" encoding="utf-8"?>
<string name="app_name">texto Desde ArrayList</string>
<string name="action_settings">Settings</string>
<string name="showCharacterTextView">Show last Character</string>
<string name="showAppendCharactersTextView">Show append Characters</string>
<string name="incomingTextEditText">Incoming text</string>
<string name="readButton">Read text</string>

Try something like this... You can get rid of the Arraylists. Remember a String is basically an array of chars. create a custom text view that implements runnable so the work that your trying to do with the text is not done on the main thread.
package com.example.stackquestion;
import java.util.ArrayList;
import android.content.Context;
import android.graphics.Color;
import android.os.SystemClock;
import android.util.AttributeSet;
import android.widget.TextView;
public class CustomTextView extends TextView implements Runnable {
String text = null;
int i = 0;
int length = 0;
String currentText = "";
public CustomTextView(Context context, AttributeSet attrs) {
super(context, attrs);
reset();
}
#Override
public void run() {
if (i < length) {
currentText = currentText + text.charAt(i);
setText(currentText);
if (text.charAt(i) == 'a') {
postDelayed(this, 500);
} else if (text.charAt(i) == 'b') {
postDelayed(this, 650);
} else if (text.charAt(i) == 'c') {
postDelayed(this, 800);
} else if (text.charAt(i) == '_') {
postDelayed(this, 1000);
} else
postDelayed(this, 1);
i++;
}
}
public void setString(String text) {
this.text = text;
this.length = text.length();
}
public void reset() {
currentText = "";
text = null;
i = 0;
setText("");
}
}
Here is the main Activity
package com.example.stackquestion;
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends Activity {
private TextView showCharacter;
private CustomTextView showAppendCharacter;
private EditText incomingText;
private Button readTextEdit;
private ArrayList<CharSequence> toText = new ArrayList<CharSequence>();
private ArrayList<Integer> timePlay = new ArrayList<Integer>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
showCharacter = (TextView) findViewById(R.id.showCharacterTextView);
showAppendCharacter = (CustomTextView) findViewById(R.id.showAppendCharacterTextView);
incomingText = (EditText) findViewById(R.id.incomingEditText);
readTextEdit = (Button) findViewById(R.id.readTextButton);
readTextEdit.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (v.getId() == R.id.readTextButton)
showAppendCharacter.reset();
showAppendCharacter
.setString(incomingText.getText().toString());
showAppendCharacter.run();
}
});
}
}
woops. I forgot to give you the Layout. But looks like you got it. Just change the type of textview to a fully qualified CustomTextView. Here was mine.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

How i can fit to all devices. Can anyone help?? Thanks in advance.

There are couple of possibilities:
use different xml files for different sizes of screen -> check here http://developer.android.com/guide/practices/screens_support.html
you may use scrollview -> http://developer.android.com/reference/android/widget/ScrollView.html
or simply make your layout fit to the smallest screen size you like to support and then just have "a little" unused space on the larger screens.
It really depends on what you need. Probably the most compatible and advanced solution would be 1.
BUT be aware of the fact that EVERY change on the screen layout has to be duplicated for each xml file following this route!

create xml for each device separately. follow this
second way:
create a parent LinearLayout and pass it to the following method
public static boolean isTabletPC(Context context) {
Display display = ((WindowManager) context
.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
if (display.getWidth() >= 1200) {
isTabletPC = true;
return isTabletPC;
} else {
isTabletPC = false;
return isTabletPC;
}
}
public static void fixUiDeviceDependencies(
Activity act, LinearLayout llParent) {
if (Utilities.isTabletPC(act)) {
Display display = ((WindowManager) act
.getSystemService(Context.WINDOW_SERVICE))
.getDefaultDisplay();
LayoutParams params = (LayoutParams) llParent
.getLayoutParams();
params.width = display.getWidth() / 2;
llParent.setLayoutParams(params);
}
}
