TableRow tr1 = new TableRow(context);
TextView hbar = new TextView(context);
tr1.addView(hbar, 0);
tl.addView(tr1,new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
I need to change the possition of textview.
hbar.setPadding(10, 0, 0, 0); not worked. and also tried with set layoutparams. any suggestions ??
set the layoutperams to the TableRow with LayoutParams.MATCH_PARENT, and then try it once.
TableRow tr1 = new TableRow(context);
TextView hbar = new TextView(context);
tr1.addView(hbar, 0);
tl.addView(tr1,new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
tl.setPadding(10,0,0,0);
here views are creating dynamically, we unable to change the positions in onCreate method, try to override the onWindowFocusChange() and then do what you want.
try this:
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
//your textview.
tl.setPadding(10,0,0,0);
}

I'm attempting to add margins to an EditText that is dynamically created, but for some reason when running the following code nothing happens.
public void addName() {
LinearLayout.LayoutParams layoutParams = new
LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
layoutParams.setMargins(30, 20, 30, 0);
row = new TableRow(this);
name = new EditText(this);
name.setHeight((int) getResources().getDimension(R.dimen.textboxHeight));
name.setBackground(getResources().getDrawable(R.drawable.textbox));
counter++;
row.addView(name, layoutParams);
namesList.addView(row);
}
If I remove the second parameter layoutParams from row.addView() it adds the row (without margins), but I want the row to be added with a margin of 15 when dynamically created. Is this possible?
I have a set of buttons that generate based on the number of items pulled from the SQLite database. The buttons generate and work fine but they center align and evenly space themselves out. Meaning if there is one: the button is centered; If there is two: they space evenly from the center; etc.
What I need is for them to stay left align and allow me to use margins to space them out. I know how to set the margins using the parameters but can't figure out why they are defaulting centered in the TableLayout row.
Again the code works and responds perfectly aside from the alignment. I've having similar issues on other activities and I'm sure it's related.
I've included some code that may show what I'm doing:
imgTitleTable = (TableLayout) findViewById(R.id.imagesTableLayout);
int i = 0;
while (i < imgTitle.length) {
if (i % 6 == 0) {
tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));
imgTitleTable.addView(tr);
imgtr = new TableRow(this);
imgtr.setLayoutParams(new LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
imgTitleTable.addView(imgtr);
}
// add images
ImageButton imgButton = new ImageButton(this);
imgButton.setImageResource(R.drawable.images_sample);
imgButton.setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1f));
imgButton.setBackground(null);
imgButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent theIntent = new Intent(getApplicationContext(),
Viewer.class);
startActivity(theIntent);
}
});
// add img title
TextView title = new TextView(this);
title.setText(imgTitle[i]);
title.setId(i);
title.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT, 1f));
title.setGravity(Gravity.CENTER);
title.setWidth(imgButton.getDrawable().getIntrinsicWidth());
title.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent theIntent = new Intent(getApplicationContext(),
Viewer.class);
startActivity(theIntent);
}
});
tr.addView(imgButton);
imgtr.addView(title);
i++;
}
Try
TableRow.LayoutParams params = new TableRow.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT,
TableLayout.LayoutParams.WRAP_CONTENT);
params.gravity=Gravity.LEFT;
imgButton.setLayoutParams(params);
I had to implement the expand/collapse(show/hide) a particular view on click of a some other view..Finally got it working but with a small problem.
I have a relative layout with two children: first is the textview and second is a linear layout.
On the click event of the textview i set the visibility(VISIBLE or GONE) of the following linear layout.
Now the problem is that after the linear layout is visible it somehow manages to hide the textview..
I tried textview.bringToFront() but it just makes the textview overlap the first row of the linearlayout ie the textview comes on top of the linear layout content.
I tried putting the textview in a linearlayout, but it makes no difference.
I tried setting the linear layout as BELOW. All in vain..
I know the textview exists because when i click the first row(which is overlapping the textview) the click event gets fired..
All i want is that no matter what my textview should be visible and the linear layout must take its position below the textview if it is visible..

well you can store your LinearLayout as an instance variable, and simply call layout.setvisibility(View.GONE); in your onClick method. Doubt theres any other solution unless you want to save the parent(the layout that both of your views are attached to) and perform findViewById inside onClick or call getChildAt(1) orso
Got a solution.. i tried setting margins..and it all worked out well.. te handle and content both are visible without hiding any other views..
I want to add linearlayout in table row and that linear layout will hold some buttons and textview.How I can achieve that.I am using this but it does not display anything
TableRow tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
final CheckBox checkbox = new CheckBox(this);
checkbox.setPadding(10, 5, 0, 0);
checkbox.setTextSize(TypedValue.COMPLEX_UNIT_PX, 15);
checkbox.setOnClickListener(new View.OnClickListener() {
TextView tv = new TextView(this);
tv.setText("Hello");
tv.setTextSize(TypedValue.COMPLEX_UNIT_PX, 14);
tv.setPadding(0, 0, 0, 0);
tv.setOnClickListener(new View.OnClickListener() {
checkbox.setLayoutParams(new LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT));
tv.setLayoutParams(new LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT));
LinearLayout linearLayout = new LinearLayout(tr.getContext());
linearLayout.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
linearLayout.setOrientation(LinearLayout.HORIZONTAL);
linearLayout.addView(checkbox, new LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT));
linearLayout.addView(tv, new LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT));
tr.addView(linearLayout);
table.addView(tr, new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
Please Help me.
Try adding row params like this
TableRow row = new TableRow(this);
row.addView(linearLayout, new TableRow.LayoutParams(1));
Add relativeLayout instead of linearlayout and set params like this for textview
RelativeLayout.LayoutParams rel_lp = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
rel_lp.addRule(RelativeLayout.BELOW);
tv.setLayoutParams(rel_lp);
For a start you need to close your curly braces at right place. While Setting onClickListener, you are not closing the curly brace and not even putting a semicolon there. So it seems you are making a textView in the listener. The following line
checkbox.setOnClickListener(new View.OnClickListener() {
should be like this
checkbox.setOnClickListener(new View.OnClickListener() {
protected void onClick(View v){
//your listener code here.
}
});
And when the layout is so complex, you should use XML files instead of Dynamically coding, unless you have to.
I'm trying to create a TableLayout programatically. It just won't work. The same layout in an xml file works though. This is what I have:
public class MyTable extends TableLayout
{
public MyTable(Context context) {
super(context);
setLayoutParams(new TableLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
TableRow row = new TableRow(context);
row.setLayoutParams(new TableRow.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
Button b = new Button(getContext());
b.setText("hello");
b.setLayoutParams(new LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
row.addView(b);
addView(row)
}
}
...
// In main activity:
MyTable table = new MyTable(this);
mainLayout.addView(table);
When I run this, I don't get a crash, but nothing appears. If I get rid of the TableRow instance, at least the button does appear as a direct child of the TableLayout. What am I doing wrong?
Just to make the answer more clear:
TableLayout.LayoutParams tableParams = new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT, TableLayout.LayoutParams.WRAP_CONTENT);
TableRow.LayoutParams rowParams = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT);
TableLayout tableLayout = new TableLayout(context);
tableLayout.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));// assuming the parent view is a LinearLayout
TableRow tableRow = new TableRow(context);
tableRow.setLayoutParams(tableParams);// TableLayout is the parent view
TextView textView = new TextView(context);
textView.setLayoutParams(rowParams);// TableRow is the parent view
tableRow.addView(textView);
Explanation
When you call setLayoutParams, you are supposed to pass the LayoutParams of the parent view
It turns out I needed to specify TableRowLayout, TableLayout etc for the layout params, otherwise the table just won't show!
For me, to get mine I had to call addContentView().
A good solution is to inflate layout files for each instance of row you want to create. See this post : How to duplicate Views to populate lists and tables?
Your problem is at this line:
b.setLayoutParams(new LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
You need to change LayoutParams to TableRow.LayoutParams:
b.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
