How to add Margin/padding in LinearLayout programmatically? - android

I am trying to set padding to my linear layouts so that when I press 'create row' they have a gap between them each.
I tried adding marginTop and marginBottom to my LinearLayout but when I run the code, the layout is still spawn in together. not with a gap from the margin I set.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="#+id/verticalLayout"
android:layout_below="#id/button"
android:background="#color/colorPrimaryDark"
android:layout_marginTop="50dp"
>
(the above image shows 3 linear layouts I added by pressing create row)
Edit: I tried adding a marginRight to it, just to see if anything worked on it, and it did.
public class MainActivity extends AppCompatActivity {
LinearLayout verticallayout,horizontalLayout; //got
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
verticallayout = findViewById(R.id.verticalLayout); //got
}
public void createRow(View view){
createRow(); //got
}
private void createRow() { //got
horizontalLayout = new LinearLayout(this);
LinearLayout.LayoutParams horizontalParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
horizontalLayout.setOrientation(LinearLayout.HORIZONTAL);
horizontalParams.setMargins(15, 5, 15, 5); // LEFT, TOP, RIGHT, BOTTOM
horizontalLayout.setLayoutParams(horizontalParams);
createSpinner();
createCheckbox();
createEditText();
verticallayout.addView(horizontalLayout, horizontalParams);
}
private void createEditText() {
EditText editText = new EditText(this);
LinearLayout.LayoutParams editParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
editParams.setMargins(10, 10, 10, 10);
editText.setLayoutParams(editParams);
horizontalLayout.addView(editText);
}
private void createCheckbox() { //done
CheckBox checkBox = new CheckBox(this);
LinearLayout.LayoutParams checkParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
checkParams.setMargins(10, 10, 10, 10);
checkParams.gravity = Gravity.LEFT;
checkBox.setLayoutParams(checkParams);
horizontalLayout.addView(checkBox);
}
private void createSpinner() {
Spinner spinner = new Spinner(this);
//ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item, spinnerArray);
//spinner.setAdapter(spinnerArrayAdapter);
LinearLayout.LayoutParams spinnerParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
spinnerParams.setMargins(10, 10, 10, 10);
spinnerParams.gravity = Gravity.LEFT;
spinner.setLayoutParams(spinnerParams);
horizontalLayout.addView(spinner);
}
}

Try this one code
private void createRow() { //got
horizontalLayout = new LinearLayout(this);
LinearLayout.LayoutParams horizontalParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
horizontalLayout.setOrientation(LinearLayout.HORIZONTAL);
horizontalParams.setMargins(15, 5, 15, 5); // LEFT, TOP, RIGHT, BOTTOM
horizontalLayout.setLayoutParams(horizontalParams);
horizontalLayout.setBackgroundColor(ContextCompat.getColor(getActivity(), R.color.colorPrimaryDark));
createSpinner();
createCheckbox();
createEditText();
verticallayout.addView(horizontalLayout, horizontalParams);
}
hope so it will be useful for you. :)

Add margin to horizontal layout not in Vertical layout. check following code:
private void createRow() {
horizontalLayout = new LinearLayout(this);
LinearLayout.LayoutParams horizontalParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
horizontalParams.topMargin = 20; //add margin here.
horizontalLayout.setOrientation(LinearLayout.HORIZONTAL);
horizontalLayout.setLayoutParams(horizontalParams);
createSpinner();
createCheckbox();
createEditText();
verticallayout.addView(horizontalLayout);
}

I want to create more than one horizontal view like flipkart main page

Object chang size(android)

Sorry for my English. I have a dynamically created TextView and ImageView, they are added to the LinearLayout. But when I start to write a TextView that it changes its size and thus reduces the ImageView. The picture below is an example of how the size of the
final LinearLayout row = new LinearLayout(this);
row.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
row.setOrientation(LinearLayout.HORIZONTAL);
//params editTExt
android.widget.LinearLayout.LayoutParams paramsEtext = new android.widget.LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1f);
paramsEtext.gravity = Gravity.LEFT;
//params image View
LinearLayout.LayoutParams paramsImageView = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 0.25f);
paramsImageView.gravity = Gravity.CENTER_VERTICAL;
//create edit text
final EditText etext = new EditText(QuicklyCreateQwestions.this);
etext.setLayoutParams(paramsEtext);
//add et in ArrayList
et.add(etext);
//set text in textView
etext.setText(qwestions.get(i).toString());
row.addView(etext);
//add ImageView in edit text
final ImageView imV = new ImageView(this);
imV.setLayoutParams(paramsImageView);
imV.setImageResource(R.drawable.t_del_poll);
imV.setId(i);
//set button in layaut
row.addView(imV);
//action if button click
imV.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
row.removeView(etext);
row.removeView(imV);
}
});
//add editText and button in layaut
LinearLayoutTextQwestions.addView(row);

Android linearlayouts not expanding as expected

I have this code below that creates a square with an image, textview and 2 image buttons.
It looks like this:
I want it so that the text is always in 1 line. The width of the square needs to expand so it includes the full text. In the image, the text gets cropped. The two little buttons (info and settings) needs to be in the corners of the square. Also there is another problem, the text is not vertically centered and it should be.
I can't quite get it to look right. Does anyone know how to fix this?
Thanks

For the text, try this answer: https://stackoverflow.com/a/2142968/2629065 it will scale down the text until it fits the parameters you give it.
You padded the top, which adds to the height of the item, offsetting the gravity alignment. Remove the top padding and use a margin, or pad the bottom.

setMargins(left, top, right, bottom); Android doesn't work

I have this code, but the textview are all without Margin right and i don't know why.
I add some lines of onCreate for declaration.
And the functions about the creation of the textview.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mLayout = (LinearLayout) findViewById(R.id.linearlayout);
mEditText = (EditText) findViewById(R.id.input_materia);
mButton = (Button) findViewById(R.id.add_materia);
mButton.setOnClickListener(onClick());
TextView textView = new TextView(this);
textView.setText("New text");
/*
* add textview from editext
*/
private OnClickListener onClick() {
return new OnClickListener() {
#Override
public void onClick(View v) {
mLayout.addView(createNewTextView(mEditText.getText().toString()));
}
};
}
private TextView createNewTextView(String text) {
final LayoutParams lparams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
lparams.setMargins(0, 0, 30, 0);
final TextView textView = new TextView(this);
textView.setLayoutParams(lparams);
textView.setText(text);
textView.setGravity(Gravity.CENTER);
return textView;
}
some helps?
Have you tried referencing Relative Layout Params or Linear Layout Params depending on what is set in your XML?
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);

Scroll Height for ScrollView does not work

i'm writing progrmicaly adding Linearlayout and Textview into ScrollView. but my ScrollView could not scroll to height.
My programicall Code:
if (cursor.moveToFirst()) {
do {
String last_ID = cursor.getString(cursor.getColumnIndex("lastId"));
String smsBody = cursor.getString(cursor.getColumnIndex("smsBody"));
String senderName = cursor.getString(cursor.getColumnIndex("senderName"));
String date[] = cursor.getString(cursor.getColumnIndex("receiveDate")).split("/");
CalendarTool ct =
new CalendarTool(
Integer.valueOf(date[0]),
Integer.valueOf(date[1]),
Integer.valueOf(date[2])
);
String IranianDate = ct.getIranianDate();
ScrollView SV =new ScrollView(this);
LinearLayout ll = new LinearLayout(this);
ll.setBackgroundColor(Color.parseColor("#f7cbad"));
ll.setOrientation(LinearLayout.VERTICAL);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.FILL_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT
);
params.setMargins(0, 0, 0, 10);
ll.setLayoutParams(params);
TextView TV_IranianDate = new TextView(this);
TV_IranianDate.setText(IranianDate);
TV_IranianDate.setTextColor(Color.parseColor("#ffffff"));
TV_IranianDate.setLayoutParams(
new ViewGroup.LayoutParams
(ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT)
);
ll.addView(TV_IranianDate);
TextView TV_smsBody = new TextView(this);
TV_smsBody.setText(smsBody);
TV_smsBody.setGravity(Gravity.RIGHT);
TV_smsBody.setLayoutParams(
new ViewGroup.LayoutParams
(ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT)
);
TV_smsBody.setPadding(5, 5, 5, 5);
ll.addView(TV_smsBody);
TextView TV_spacer2 = new TextView(this);
TV_spacer2.setBackgroundColor(Color.parseColor("#000000"));
TV_spacer2.setLayoutParams(
new ViewGroup.LayoutParams
(ViewGroup.LayoutParams.FILL_PARENT,
1)
);
ll.addView(TV_spacer2);
SV.addView(ll);
((LinearLayout) linearLayout).addView(SV);
} while (cursor.moveToNext());
}
I guess the problem is the ScrollView object. You should use HorizontalScrollView instead, like this for example:
HorizontalScrollView SV = new HorizontalScrollView(this);
SV.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));
like described in the API:
ScrollView only supports vertical scrolling. For horizontal scrolling, use HorizontalScrollView.
