I'm having a problem with LinearLayout where I want to display a TableLayout after a TextView. I've tried modifying the LayoutParams however I can't seem to make it wrap (which I'm assuming I want it to do).
This is simplified version:
ScrollView sv = (ScrollView) findViewById(R.id.sv);
sv.removeAllViews();
LinearLayout ll = new LinearLayout(this);
sv.addView(ll);
//This is displayed
TextView tv = new TextView(this);
tv.setText("Hello World");
ll.addView(tv);
//This is not displayed - but if I remove the above view it will display...
TableLayout tl = new TableLayout(this);
ll.addView(tl, new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));
By specifiying Orientation as Vertical it worked for me:
ScrollView sv = (ScrollView) findViewById(R.id.sv);
sv.removeAllViews();
LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
sv.addView(ll);
TextView tv = new TextView(this);
tv.setText("Hello World");
ll.addView(tv);
TableLayout tl = new TableLayout(this);
ll.addView(tl);

how can I do something like this programmatically? There must be one Checkbox and two vertical textview in MaterialCardView.I tried using Linearlayout but I can't solve it.
LinearLayout.LayoutParams layoutparams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT
);
linearLayout.setOrientation(LinearLayout.VERTICAL);
mCardView=new MaterialCardView(this);
mCardView.setLayoutParams(layoutparams);
mCardView.setElevation(2);
linearLayout.addView(mCardView);
LinearLayout linearLayout1=new LinearLayout(this);
linearLayout1.setOrientation(LinearLayout.HORIZONTAL);
linearLayout1.setLayoutParams(layoutparams);
linearLayout.addView(linearLayout1)
checkBox=new CheckBox(this);
linearLayout1.addView(checkBox);
txt_baslik=new TextView(this);
txt_tarih=new TextView(this);
txt_baslik.setLayoutParams(layoutparams);
txt_tarih.setLayoutParams(layoutparams);
txt_baslik.setText("deneme baslik");
txt_tarih.setText("deneme tarih");
linearLayout1.addView(txt_baslik);
linearLayout1.addView(txt_baslik);
LinearLayout linearLayout2=new LinearLayout(this);
linearLayout2.setOrientation(LinearLayout.VERTICAL);
linearLayout2.setLayoutParams(layoutparams);
linearLayout.addView(linearLayout2);
I'm so confused
you can do like that :
LinearLayout.LayoutParams layoutparams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
LinearLayout linearLayout=new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.HORIZONTAL);
CardView mCardView=new MaterialCardView(this);
mCardView.setLayoutParams(layoutparams);
mCardView.setElevation(2);
CheckBox checkBox=new CheckBox(this);
LinearLayout.LayoutParams checkBoxParam = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
checkBoxParam.gravity = Gravity.CENTER;
checkBox.setLayoutParams(checkBoxParam);
LinearLayout verticalLinLayout=new LinearLayout(this);
verticalLinLayout.setOrientation(LinearLayout.VERTICAL);
verticalLinLayout.setLayoutParams(layoutparams);
TextView txt_baslik=new TextView(this);
TextView txt_tarih=new TextView(this);
txt_baslik.setLayoutParams(layoutparams);
txt_tarih.setLayoutParams(layoutparams);
txt_baslik.setText("deneme baslik");
txt_tarih.setText("deneme tarih");
verticalLinLayout.removeAllViews();
verticalLinLayout.addView(txt_baslik);
verticalLinLayout.addView(txt_tarih);
linearLayout.addView(checkBox);
linearLayout.addView(verticalLinLayout);
mCardView.addView(linearLayout);
don't forgor add mCardView into your parent view at last.
Currently, I am trying to code a textview and a edittext to align vertically using Linearlayout in android studio. I tried setting out the layout gravity and the other element but I cannot achieve what I want currently this is my code.
LinearLayout params3 = new LinearLayout(this);
params3.setOrientation(LinearLayout.VERTICAL);
params3.setGravity(Gravity.CENTER_VERTICAL);
LinearLayout.LayoutParams params2 = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
params2.weight = 35;
params3.setLayoutParams(params2);
params2.height = convertDiptoPix(80,context);
//params2.leftMargin = convertDiptoPix(5,context);
TextView textView1 = new TextView(this);
textView1.setId(View.generateViewId());
textView1.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL);
textView1.setPadding(0,convertDiptoPix(1,context),0,convertDiptoPix(3,context));
textView1.setText("Receipt");
textView1.setTextColor(Color.parseColor("#000000"));
//textView1.setLayoutParams(params2);
textView1.setTextSize(convertDiptoPix(13,context));
EditTextIME editTextIME = new EditTextIME(this);
editTextIME.setId(View.generateViewId());
//editTextIME.setWidth(LinearLayout.LayoutParams.MATCH_PARENT);
//editTextIME.setMinimumHeight(LinearLayout.LayoutParams.WRAP_CONTENT);
editTextIME.setGravity(Gravity.BOTTOM | Gravity.CENTER_VERTICAL);
//editTextIME.setLayoutParams(params2);
editTextIME.setFocusableInTouchMode(true);
editTextIME.setKeyListener(DigitsKeyListener.getInstance("abcdefghijklmnopqrstuvwxyzöäüßñéúíóáèùòìàâãåæçëêìíîïôõûýABCDEFGHIJKLMNOPQRSTUVWXYZÖÄÜÕÔÒÔÓÙÚÛÝÑÇÈÉÊËÌÍÎÏÆÅÄÃÂÁÀØ01234567890()&*$%#!+-:;,._?¿/><[]{}|\\^ "));
editTextIME.setHint("Notes");
editTextIME.setInputType(InputType.TYPE_CLASS_TEXT);
editTextIME.setHorizontallyScrolling(true);
editTextIME.setTextSize(convertDiptoPix(13,context));
is anyone had anyone tried to code like vertical align in android studio? Can you share your idea?
You can try this,
LinearLayout parent = new LinearLayout(context);
parent.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
parent.setOrientation(LinearLayout.VERTICAL);
LinearLayout.LayoutParams params2 = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
TextView textView1 = new TextView(this);
textView1.setLayoutParams(params2);
textView1.setId(View.generateViewId());
textView1.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL);
textView1.setText("Receipt");
textView1.setTextColor(Color.parseColor("#000000"));
EditText editTextIME = new EditText(this);
editTextIME.setId(View.generateViewId());
editTextIME.setGravity(Gravity.BOTTOM | Gravity.CENTER_VERTICAL);
editTextIME.setLayoutParams(params2);
editTextIME.setFocusableInTouchMode(true);
editTextIME.setKeyListener(DigitsKeyListener.getInstance("abcdefghijklmnopqrstuvwxyzöäüßñéúíóáèùòìàâãåæçëêìíîïôõûýABCDEFGHIJKLMNOPQRSTUVWXYZÖÄÜÕÔÒÔÓÙÚÛÝÑÇÈÉÊËÌÍÎÏÆÅÄÃÂÁÀØ01234567890()&*$%#!+-:;,._?¿/><[]{}|\\^ "));
editTextIME.setHint("Notes");
editTextIME.setInputType(InputType.TYPE_CLASS_TEXT);
editTextIME.setHorizontallyScrolling(true);
// editTextIME.setTextSize(convertDiptoPix(13,context));
parent.addView(textView1);
parent.addView(editTextIME);
I have created programmatically a RelativeLayout which contains a button. I have also created a ScrollView which contains a LinearLayout in which are more than 10 TextViews. I want to have the RelativeLayout to be aligned top and fixed. When someone tries to scroll down, i want all the TextViews to go behind the fixed RelativeLayout. I want that button to be always visible. With this code, the RelativeLayout and the button are not displayed. Where am i wrong?
RelativeLayout (fixed)
- Button
LinearLayout
- ScrollView
- TextView
- + other 10 TextViews
Here is my code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final RelativeLayout relativeLayout = new RelativeLayout(this);
RelativeLayout.LayoutParams relativeLayoutParams = new RelativeLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
relativeLayout.setLayoutParams(relativeLayoutParams);
this.setContentView(relativeLayout);
final Button restartButton = new Button(this);
restartButton.setText(R.string.restartButton);
LinearLayout.LayoutParams buttonParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
restartButton.setLayoutParams(buttonParams);
relativeLayout.addView(restartButton);
ScrollView scrollView = new ScrollView(this);
this.setContentView(scrollView);
final LinearLayout linearLayout = new LinearLayout(this);
LinearLayout.LayoutParams linearLayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
linearLayout.setLayoutParams(linearLayoutParams);
linearLayout.setOrientation(linearLayout.VERTICAL);
scrollView.addView(linearLayout);
TextView textView1 = new TextView(this);
testTitle.setText(R.string.text_view1);
linearLayout.addView(textView1);
// + other 10 text views
}
Thanks!
In your code you replace your RelativeLayout with ScrollView. Just set firstly some LinearLayout as contentView and then put there your RelativeLayout via addView(relativeLayout) and the put there you scrollView also via addView(scrollView)
EDIT:
your new code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final LinearLayout mainLinearLayout = new LinearLayout(this);
LinearLayout.LayoutParams mainLinearLayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
mainLinearLayout.setLayoutParams(mainLinearLayoutParams);
mainLinearLayout.setOrientation(LinearLayout.VERTICAL);
this.setContentView(mainLinearLayout);
final RelativeLayout relativeLayout = new RelativeLayout(this);
RelativeLayout.LayoutParams relativeLayoutParams = new RelativeLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
relativeLayout.setLayoutParams(relativeLayoutParams);
mainLinearLayout.addView(relativeLayout);
final Button restartButton = new Button(this);
restartButton.setText(R.string.restartButton);
LinearLayout.LayoutParams buttonParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
restartButton.setLayoutParams(buttonParams);
relativeLayout.addView(restartButton);
ScrollView scrollView = new ScrollView(this);
mainLinearLayout.addView(scrollView);
final LinearLayout linearLayout = new LinearLayout(this);
LinearLayout.LayoutParams linearLayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
linearLayout.setLayoutParams(linearLayoutParams);
linearLayout.setOrientation(linearLayout.VERTICAL);
scrollView.addView(linearLayout);
TextView textView1 = new TextView(this);
testTitle.setText(R.string.text_view1);
linearLayout.addView(textView1);
// + other 10 text views
}
EDIT 2: renamed first linearLayout to mainLinearLayout according to the comment
How to add EditText programmatically?
Here's what I wrote:
View RV = inflater.inflate(R.layout.fragment__dummy,container, false);
LinearLayout LL = new LinearLayout(getActivity());
EditText ET = new EditText(getActivity());
ET.setId(5);
ET.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
LL.addView(ET);
return RV;
Thank You!
LinearLayout layout=(LinearLayout)view.findViewById(R.id.linearLayout);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
android.widget.LinearLayout.LayoutParams.MATCH_PARENT,
android.widget.LinearLayout.LayoutParams.WRAP_CONTENT);
EditText edttext= new EditText(this);
edttext.setId("edittext");
edttext.setLayoutParams(params);
layout.addView(edttext);
You are creating the LinearLayout LL dynamically too.
You need to add it to RV like
((ViewGroup)RV).addView(LL);
Also you should set the LayoutParams for LL too
I try to create dynamically linerlayout and i created two buttoms.
LinearLayout layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.HORIZONTAL);
layout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
TextView titleView = new TextView(this);
titleView.setWidth(LayoutParams.WRAP_CONTENT);
titleView.setHeight(LayoutParams.WRAP_CONTENT);
titleView.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
titleView.setText("Hallo Welt!");
layout.addView(titleView);
Button btnConnect = new Button(this);
btnConnect.setText("Connect");
layout.addView(btnConnect);
Button btnDisconnect = new Button(this);
btnDisconnect.setText("Disconnect");
layout.addView(btnDisconnect);
I want to put Connect button to left corner and want to put disconnet button to the right corner. How can i do that?
Have you tried to set layout gravity for your buttons?
LayoutParams params;
Button btnConnect = new Button(this);
params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.Left;
btnConnect.setLayoutParams(params);
...
Button btnDisconnect = new Button(this);
params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.Right;
btnConnect.setLayoutParams(params);
...
Layout gravity defines where to place a view in its parent (see Gravity and layout_gravity on Android too)
Cheers
You can use RelativeLayout instead of linear layout.
and add rules to the layout params of the
RelativeLayout.Layoutparams params = RelativeLayout.Layoutparams params = (RelativeLayout.LayoutParams)button.getLayoutParams();
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
