I want to make a layout that it
LinearLayout
ScrollView
LinearLayout
but it seems like the ScrollView has cover the rest of LinearLayout.
LinearLayout all = new LinearLayout(this);
LinearLayout upper = new LinearLayout(this);
LinearLayout footer = new LinearLayout(this);
ScrollView sv = new ScrollView(this);
all.setOrientation(LinearLayout.VERTICAL);
upper.setOrientation(LinearLayout.HORIZONTAL);
footer.setOrientation(LinearLayout.HORIZONTAL);
TextView code = new TextView(this);
code.setText("Code : ");
EditText codeEdit = new EditText(this);
upper.addView(code);
upper.addView(codeEdit);
LinkedList<LinearLayout> lk = new LinkedList<LinearLayout>();
TextView[] tt = new TextView[100];
LinearLayout ll= new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
for(int a = 0 ; a < 100; a++){
LinearLayout temp = new LinearLayout(this);
temp.setOrientation(temp.HORIZONTAL);
tt[a] = new TextView(this);
tt[a].setText("Hello " + a);
temp.addView(tt[a]);
lk.add(temp);
ll.addView(temp);
}
sv.addView(ll);
Button next = new Button(this);
next.setText("Next");
footer.addView(next);
all.addView(upper);
all.addView(sv);
all.addView(footer);
setContentView(all);
The scrollview is too large and cover the rest of the linearlayout, the linearlayout after is not showing becasue of the scrollview.
How can I actually solve this?
Do like this
LinearLayout dummy = new LinearLayout(this);
dummy.setLayoutParams(new LinearLayout.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT, 1));
dummy.addView(sv);
add one linearlayout to wrap the scrollview inside it
instead of adding scroolview add this dummy linearlayout

Hello everyone please i need help. I'm a biginner in Android programming so since i was trying to solve this problem it took me all my days that why i want you to help me please. I'm trying to display a Linear layout according to the loop condition but the issue is that when i'm doing that it's just displaying the last one and i'm not able to see others when it's displaying. Here are my codes
ScrollView sv = new ScrollView(this);
sv.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
sv.setPadding(5, 5, 5, 5);
sv.setBackgroundColor(getResources().getColor(R.color.colorWhite));
LinearLayout ll = null;
for (int i=0; i < 2; i++){
try {
//Here iam defining the LinearLayout
ll = new LinearLayout(this);
ll.setId(i);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
ll.setLayoutParams(params);
ll.setOrientation(LinearLayout.VERTICAL);
ll.setBackground(getDrawable(R.drawable.circle_view));
//Here iam defining the RelativeLayout
RelativeLayout Rl = new RelativeLayout(this);
RelativeLayout.LayoutParams param = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
Rl.setLayoutParams(param);
//Defining a layout params for widgets
RelativeLayout.LayoutParams image = new RelativeLayout.LayoutParams(100, 90);
image.addRule(RelativeLayout.ALIGN_LEFT);
//Creating widgets
ImageView im = new ImageView(this);
im.setImageResource(R.mipmap.airtel);
im.setId(R.id.image1);
im.setLayoutParams(image);
//----------------
RelativeLayout.LayoutParams txtone = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
txtone.addRule(RelativeLayout.RIGHT_OF, R.id.image1);
txtone.setMargins(0, 5, 0, 45);
TextView txtVone = new TextView(this);
txtVone.setText("ArkaL"+i);
//txtVone.setTextSize(R.dimen.MainTextSize);
txtVone.setTextSize(15);
txtVone.setTypeface(txtVone.getTypeface(), Typeface.BOLD);
txtVone.setLayoutParams(txtone);
//------------------------------------------------
RelativeLayout.LayoutParams txttwo = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
txttwo.addRule(RelativeLayout.RIGHT_OF, R.id.image1);
txttwo.setMargins(0, 45, 0, 0);
TextView txtVtwo = new TextView(this);
txtVtwo.setText("République Démocratique du Congo");
txtVtwo.setTypeface(txtVtwo.getTypeface(), Typeface.SERIF.getStyle());
txtVtwo.setTextSize(10);
txtVtwo.setLayoutParams(txttwo);
Rl.addView(im);
Rl.addView(txtVone);
Rl.addView(txtVtwo);
RelativeLayout.LayoutParams recycler = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
RecyclerView rv = new RecyclerView(this);
rv.setLayoutParams(recycler);
ll.addView(Rl);
ll.addView(rv);
}catch (Exception e){
}
}
//Here for assigning Linear to ScrollView
sv.addView(ll);
this.setContentView(sv);
Please help me.
your problem is that you created one LinearLayout and changed it in a loop and then added it to a ScrollView so at the end you will have just one LinearLayout. as you may know an ScrollView should have just one View as a child view so you should add a LinearLayout for a ScrollView and add as many LinearLayout as you want to the primary LinearLayout. your code can be like this:
LinearLayout llMain = new LinearLayout(this);
LinearLayout.LayoutParams params2 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
llMain.setLayoutParams(params2);
llMain.setOrientation(LinearLayout.VERTICAL);
sv.addView(llMain);
LinearLayout ll = null;
for (int i = 0; i < 2; i++) {
try {
//Here iam defining the LinearLayout
ll = new LinearLayout(this);
ll.setId(i);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
ll.setLayoutParams(params);
ll.setOrientation(LinearLayout.VERTICAL);
...
llMain.addView(ll);
} catch (Exception e) {
...
note that the Height of primary linearlayour should wrap its content;
I want to create a relative layout inside a linear layout dynamically.This relative layout contains a text view and button which are also created in dynamic method.The alignment of text view and button not work properly.The code which i have tried is given below.
final LinearLayout lab_linear = (LinearLayout) findViewById(R.id.contact_list_layout);
lab_linear.setOrientation(LinearLayout.VERTICAL);
for (int i = 0; i < Size_contact; i++)
{
RelativeLayout layout = new RelativeLayout(this);
RelativeLayout.LayoutParams lp = new
RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT,RelativeLayout.LayoutParams.WRAP_CONTENT);
layout.setLayoutParams(lp);
final TextView Questions_value = new
android.widget.TextView(getApplicationContext());
Questions_value.setText(contact_name.get(i));
Questions_value.setTextSize(18);
Questions_value.setId(i);
layout.addView(Questions_value);
Button myButton = new Button(this);
myButton.setBackgroundResource(R.drawable.close);
myButton.setLayoutParams(new LayoutParams(20,20));
layout.addView(myButton);
lab_linear.addView(layout);
}
Try this..
Give layout parems for RelativeLayout individually to TextView and Button and also add addRule(RelativeLayout.ALIGN_PARENT_RIGHT); or addRule(RelativeLayout.ALIGN_PARENT_LEFT); for that views
Or add the below in for Button
lp1.addRule(RelativeLayout.RIGHT_OF, Questions_value.getId());
for (int i = 0; i < Size_contact; i++)
{
RelativeLayout layout = new RelativeLayout(this);
RelativeLayout.LayoutParams lp = new
RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT,RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
final TextView Questions_value = new
android.widget.TextView(getApplicationContext());
Questions_value.setText(contact_name.get(i));
Questions_value.setTextSize(18);
Questions_value.setId(i);
layout.addView(Questions_value,lp);
RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
lp1.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
//Or below remove above code and uncomment the below code
//lp1.addRule(RelativeLayout.RIGHT_OF, Questions_value.getId());
Button myButton = new Button(this);
myButton.setBackgroundResource(R.drawable.close);
myButton.setLayoutParams(new LayoutParams(20,20));
layout.addView(myButton,lp1);
lab_linear.addView(layout);
}
Might I suggest using LinearLayouts instead of RelativeLayouts in your loop? That way, you won't have the overlap problem.
Here is my code to display table layout below linear layout.here i am setting scroll view as contentview.but only table layout displaying on screen.here any problem in layout.please help me thanks.
ScrollView scrollView = new ScrollView(this);
LinearLayout ll = new LinearLayout(getApplicationContext());
ll.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
Button btn1 = new Button(this);
btn1.setText("Button1");
ll.addView(btn1);
btn1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
TableLayout resultLayout = new TableLayout(this);
resultLayout.setStretchAllColumns(true);
resultLayout.setShrinkAllColumns(true);
Here tried by placing the linear layout above the table layout now only linearlayout displaying
LinearLayout ll = new LinearLayout(getApplicationContext());
ll.setOrientation(LinearLayout.VERTICAL);
ll.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
// Set the TextView for the Question
TextView tv1 = new TextView(getApplicationContext());
tv1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
tv1.setText("HI");
ll.addView(tv1);
ScrollView scrollView = new ScrollView(this);
TableLayout resultLayout = new TableLayout(this);
resultLayout.setStretchAllColumns(true);
resultLayout.setShrinkAllColumns(true);
//Here i have table rows code
ll.addView(scrollView);
setContentView(ll);
now setting linear layout as contentview as per your answers scroll view contains only table layout.but why it is not displaying in the screen
ScrollViews in android should contain only a single child. So might I suggest you add a LinearLayout inside the ScrollView and then add the other components in this LinearLayout
check this:\
LinearLayout ll = new LinearLayout(getApplicationContext());
ll.setOrientation(LinearLayout.VERTICAL);
ll.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
// Set the TextView for the Question
TextView tv1 = new TextView(getApplicationContext());
tv1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
tv1.setText("HI");
ll.addView(tv1);
ScrollView scrollView = new ScrollView(this);
scrollView.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
TableLayout resultLayout = new TableLayout(this);
resultLayout.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
scrollView.addView(resultLayout);
resultLayout.setStretchAllColumns(true);
resultLayout.setShrinkAllColumns(true);
ll.addView(scrollView);
I am adding TextView dynamically using for loop to LinearLayout which orientation is horizontal. Is it possible to align the TextView to second line if it reach end of screen width?
You can do it in the following manner:
LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
LinearLayout layout = new LinearLayout(this);
LinearLayout layout1 = new LinearLayout(this);
LinearLayout layout2 = new LinearLayout(this);
layout.setOrientation(LinearLayout.VERTICAL);
layout1.setOrientation(LinearLayout.HORIZONTAL);
layout2.setOrientation(LinearLayout.HORIZONTAL);
for (int i = 0; i < 3; i++) {
TextView lblView = new TextView(this);
TextView lblView2 = new TextView(this);
lblView.setLayoutParams(params);
lblView.setText("hello");
lblView.setEms(5);
lblView.setGravity(Gravity.CENTER);
lblView2.setLayoutParams(params);
lblView2.setText("hello");
lblView2.setEms(5);
lblView2.setGravity(Gravity.CENTER);
layout1.addView(lblView);
layout2.addView(lblView2);
}
layout.addView(layout1);
layout.addView(layout2);
setContentView(layout);
The following will do the trick,
textview.setLayoutParams(new LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));
I tried the below code to create multiple buttons through programatically but it creates a single button as per my application i need to create a button based on input. For example if the input is 3 means i need to create three buttons in a layout. For your reference i attached the sample image and my code.
for (int i = 0; i < array_of_btn_input.size(); i++) {
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
LinearLayout layout = new LinearLayout(getApplicationContext());
LinearLayout.LayoutParams params1 = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
layout.setOrientation(LinearLayout.VERTICAL);
layout.setLayoutParams(params);
Button button1 = new Button(getApplicationContext());
button1.setLayoutParams(params1);
button1.setText("button");
layout.addView(button1);
main_layer.addView(layout);
}
if in your example, your global container (main_layer) is a relativelayout or a frame layout, you have placed them on top of eachother. So you can't see the one on the back order.
Try this pls,
LinearLayout main_layer= (LinearLayout) findViewById(id.main_layer);
for (int i = 0; i < 10; i++)
{
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);
LinearLayout layout = new LinearLayout(getApplicationContext());
LinearLayout.LayoutParams params1 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);
layout.setOrientation(LinearLayout.VERTICAL);
layout.setLayoutParams(params);
Button button1 = new Button(getApplicationContext());
button1.setLayoutParams(params1);
button1.setText("button");
layout.addView(button1);
main_layer.addView(layout);
}
You are creating multiple new linear layouts within the for loop. Linear layout need to be taken out of the for loop and just try adding the buttons in it.
1st run of for loop creates a new linear layout and adds a button
2nd run of for loop creates a new linear layout and adds a button on the top of previous added layout
Here you are creating a new LinearLayout per button... Try something more like...
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
LinearLayout layout = new LinearLayout(getApplicationContext());
layout.setOrientation(LinearLayout.VERTICAL);
layout.setLayoutParams(params);
for (int i = 0; i < array_of_btn_input.size(); i++) {
LinearLayout.LayoutParams params1 = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
Button button1 = new Button(getApplicationContext());
button1.setLayoutParams(params1);
button1.setText("button");
layout.addView(button1);
}
main_layer.addView(layout);
Try this
LinearLayout llParent = (LinearLayout) findViewById(R.id.llParent);
llParent.removeAllViews();
for (int i = 0; i < array_of_btn_input.size(); i++) {
BSView b = new BSView(this, new SimpleThumbBean(i + 1, bsList
.get(i).getLabel(), bsList.get(i).getThumbUrl()));
LinearLayout.LayoutParams llDynamic = new LinearLayout.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
llDynamic.weight = 1f;
llParent.addView(b, llDynamic);
}
llParent is a defined Layout and make sure you call removeAllViews() before adding layouts dynamically into it.
BSView is my own custom View. You can set BSView into ordinary Button as you need it.
