I simply want to know . is there a way to create an id's using for loop
I have 10 buttons in xml . there id's are button1,button2,button3... button10 Now i create an Array of Button in java class and do it like this
public class Menu extends Activity
{
Button[] arrayButton=new Button[10];
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.menu);
init();
}
private void init()
{
for(int i=1 ; i<9 ; i++)
{
String abc = "but"+String.valueof(i);
int x = Integer.parseInt(abc);
Log.d("abc", abc);
Log.d("x", String.valueOf(x) );
//arrayButton[i] = (Button) findViewById(R.id.x); // giving error
//arrayButton[i].setText("Hello:");
}
}
}
I want to know how can i do this kind of work . Getting all button using for loop to make my work faster and some time when i want to set the text of all the buttons .
use getResources().getIdentifier like
String abc = "but"+String.valueof(i);
int resID = getResources().getIdentifier(abc, "id", getPackageName());
arrayButton[i] = (Button) findViewById(resID );
arrayButton[i].setText("Hello:");
i.e. simply rewrite init() method as
private void init()
{
for(int i=1 ; i<9 ; i++)
{
String abc = "but"+String.valueof(i);
int resID = getResources().getIdentifier(abc, "id", getPackageName());
arrayButton[i] = (Button) findViewById(resID);
arrayButton[i].setText("Hello:");
}
}
Or simple you may use
int[] buttonIDs = new int[] {R.id.but1, R.id.but2, R.id.but3,R.id.but4, ... }
for(int i=0; i<buttonIDs.length; i++) {
Button b = (Button) findViewById(buttonIDs[i]);
b.setText("Hello:" + b.getText().toString());
}
If you already know all the ids, you can simply use:
int [] ids = new int [] {R.id.btn1, R.id.btn2, ...};
Button [] arrayButton = new Button[ids.length];
for(int i=0 ; i < arrayButton.length ; i++)
{
arrayButton[i] = (Button) findViewById(ids[i]);
}
Or if you don't know them, use:
getResources().getIdentifier("btn1","id",getPackageName())
Try this way,hope this will help you to solve your problem.

#Override

arrayButton=new Button[10];

for(int i=0;i<lnrMain.getChildCount() ; i++)
{
arrayButton[i] = (Button) lnrMain.getChildAt(i);
arrayButton[i].setText("Hello:"+(i+1));
}
}
}
You can create a helper void like:
public static int getResourceID(Context mContext, String StrId) {
return mContext.getResources().getIdentifier(StrId, "id", mContext.getPackageName());
}

I define layout row which I inflate and add view pragmatically to a linear layout.
I wanna something like this,
https://i.stack.imgur.com/EKPmJ.png
Here is xml of my main activity where I am inflating the costume view row
<?xml version="1.0" encoding="utf-8"?>

</LinearLayout>
here is my xml code of row which I am inflating:

int newValue = result + 1;
if (newValue > 0x00FFFFFF) newValue = 1; // Roll over to 1, not 0.
if (viewIdGenerator.compareAndSet(result, newValue)) {
return result;
}
}
}
}
but when I inflate row my image view get cutoff which I not want I tried with negative margin but it not work
here what it looks like
custom overlapping row
what I do so I over lap image to above view?
Try changing your layout to this.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="its text view"
/>
<Button
android:id="#+id/nameButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/name"
/>
</RelativeLayout>
<ImageView
android:layout_marginTop="25dp"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher_round"/>
</RelativeLayout>
When you put in another row, that row needs to be pushed up so the android icon that is there now overlays it.
Is there any why to show the fraction neat and clean in android
denominator, horizontal line and numerator
For example
4/5+x + 3
would be
4
_____ + 3
5 + x
Actually i want to show the algebraic equation on run time.
please tell me the answer i am working on this since four or five days but no success is achieved.

I know this is probably really simple but looking online doesn't answer it...
why does this crash upon getting to here?:

Edit*
Search() is an onClick button in ps.xml while the textview are in list.xml
Inside your onCreate() method:
change from setContentView(R.layout.ps); to setContentView(R.layout.list); because you are using list.xml as your main layout.
and delete this line setContentView(R.layout.list); inside your Search() method:
public void Search(View view) {
int clist = -2;
String oID = "";
String oName = "";
String oWorld = "";
// Delete this line setContentView(R.layout.list);
while (clist != -1)
{
oID = tID.getText().toString();
tID.setText(oID+"ddf"+"\n");
oName = tName.getText().toString();
clist = -1;
}
}
In my project need to make layout listview with edit text
please suggest me how i can make this kind of layout

In my code, If we need particular number of checkbox or radio button, by giving the count value in EditText, we can get the particular number of checkbox. But It is displaying the checkbox with random alphabets from a to z. But, I need it to change/rename specifically based on my need. Your help is highly appreciated. Thanks in advance.

make an String Array like

then in the code

CheckBox ch = new CheckBox(this);
ch.setId((row * 2) + i);
// Replace the line with
//ch.setText(randomString(3));
// with this line
ch.setText(names[i]);
ll.addView(ch);
}
In your addCheckBox() method, you have set the text of checkbox to randomstring (ch.setText(randomString(3))). Just change this line as your choice just like this ch.setText("Checkbox" + i).
for (int i = 1; i <= number; i++) {
CheckBox ch = new CheckBox(this);
ch.setId((row * 2) + i);
ch.setText(randomString(3)); // Change Here
ll.addView(ch);
}
change the text of checkBox in ch.setText that you want to be
Ok.. I really don't understand... When you create the checkbox you set its text to ch.setText(randomString(3)); Why would you do that if you want specific text ?
Random != Specific.
Just write something like this:
ch.setText("Your desired text");
Or you could create an
String[] checkBoxFruits= {"apple","mango","kiwi"};
and then set the text something like:
for ( int i=0; i<numberOfCheckBoxes; i++ )
{
CheckBox ch = new CheckBox(this);
ch.setId((row * 2) + i);
ch.setText(checkBoxFruits[i]);
ll.addView(ch);
}
public void addCheckBox(int number) {
String[] names = {"Sanket", "Kumar", "Eagle"};
for (int row = 0; row < 1; row++) {
LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.HORIZONTAL);
for (int i = 1; i <= number; i++) {
CheckBox ch = new CheckBox(this);
ch.setId((row * 2) + i);
if(i != names.length)
ch.setText(names[i-1]);
else
ch.setText("New name");
ll.addView(ch);
}
((ViewGroup) findViewById(R.id.radiogroup)).addView(ll);
}
}
Use above code.. And check it...
I think you should try using RadioGroup and create an array of strings with which can easily use .setText method to run a loop throgh all the Radio Buttons.
