Suppose I have a view inside TableLayout, like this:
TableLayout tableLayout;
View view = (View)tableLayout.findViewById(R.id.control);
How can I find out the view's row/column within the TableLayout?

I am trying to create a basic datasheet in my application using a TableLayout. The first row contains the titles of each column. Every row thereafter is data. I would like the data to be scrollable while keeping the first title row visible (i.e. the first row would not scroll with the rest).I have tried something like the following (unsuccessfully)

Is it possible for my android application to dynamically adjust the no of column and no of row of my TableLayout based on orientation?

View 2 Replies View RelatedSo my layout looks basically like this:
<ScrollView>
<RelativeLayout>
<BunchOfViews/>
<ImageView android:layout_alignParentBottom="true"/>
</RelativeLayout>
</ScrollView>
I have the ScrollView so all of the layout always is visible no matter the height of the screen. The problem is that on a very high screen, I still want my imageview to be at the bottom. However, a child of a ScrollView dont seem to have a defined bottom. The View is placed at the top of the layout. How can I solve this problem in a neat way?
Before I added my ListView, along with changing my TableLayout height to "wrap_content" as opposed to "fill_parent", my ScrollView displayed properly. Here is my XML: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" Code...
View 1 Replies View RelatedHow do I set up an xml layout where an OpenGL view is part of it? As I do now is set the OpenGL view as the only view with setContentView(). But I would like to create an xml layout that includes the OpenGL view. Lets say I want to have the OpenGL view mainly and a small TextView at the bottom.
Is this even possible? Or can an OpenGL view only be the one and only view?
I'm trying to build an activity that has a checkbox on top, a button at the bottom, and a bunch of other widgets scrolling in between. Conceptually that'sWhen it renders I get the checkbox at the top, the stuff scrolling nicely underneath, but the Button drawn offscreen (I assume) below the ScrollView. The only way I can get the Button to be visible is to hard-code the height of the ScrollView, which of course only works on one screen-size. I've tried all combinations of gravity and layout_weight I can think of to no avail. Am I using the right combination of Views? Anybody managed to get this working?
View 1 Replies View RelatedI'm not big into UI programming so this may be an easy thing I overlooked. I am trying have a screen that shows 8 TextView in a 2 column x 4 row table. And, of course, I want the TextViews, that might have different lengths, to be centered. I tried this in a table layout, for obvious reasons but I feel like this is not the way to do it because it doesn't have much control where I put everything once it is in a row. Should I be using a different combinations of layouts or is there something I overlooked.
View 2 Replies View RelatedHere is my screen description: It is a TableLayout and it contains multiple Rows. I have set TableRow as clickable, as I want to go to next screen on click of a tableRow. Everything I am doing through Java programming (instead of XML layout, because number of TableRows changes each time) On next screen, I wanted to display all the views of that particular clicked TableRow. Here the problem i am facing is how to capture particular tableRow on onclick() even and how do I get all the textviews of that particular Row. I tried to set id at runtime, and tried to get id of view, but it's not working, giving error resourcenotfoundexception.
View 2 Replies View RelatedI want to have a dynamic table, with rows added over time as a result of user interaction, using a TableLayout inside a ScrollView. This works fine, but when I want to scroll to the end of the table using fullScroll(), it always leaves out the last line; that is, it scrolls so that the one before the last one is visible. The last line is visible when scrolling manually, and the scrollbar is correct too.I'm of course open to suggestions as to how to make a better layout out of this; but I'm specifically interested in understanding why fullScroll() behaves that way. Should I give it a different parameter, or use something else altogether? Or does it do that because the newly added line isn't yet visible somehow? (if so, how can I solve that?) Or did I miss some other obvious thing?The following code replicates the problem: TestActivity.java:
package com.example.android.tests;
import java.util.Random;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ScrollView;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TextView;
public class TestActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById(R.id.AddRow)).setOnClickListener(new View.OnClickListener() { public void onClick(View v) {
Random rnd = new Random();
TableRow nr = new TableRow(v.getContext());
for (int c=0; c<3; c++) {
TextView nv = new TextView(v.getContext());
nv.setText(Integer.toString(rnd.nextInt(20)-10));
nr.addView(nv);
}((TableLayout) findViewById(R.id.Table)).addView(nr);
// Scrolls to line before last - why?
((ScrollView) findViewById(R.id.TableScroller)).fullScroll(View.FOCUS_DOWN);
}main.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button
android:text="Add Row"
android:id="@+id/AddRow"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" />
<ScrollView
android:id="@+id/TableScroller"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="@id/AddRow"
android:layout_alignParentTop="true" >
<TableLayout
android:id="@+id/Table"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stretchColumns="0,1,2" />
</ScrollView>
</RelativeLayout>
Edit: for reference, I implemented Romain Guy's solution as follows:In TestActivity.java, replace:
// Scrolls to line before last - why?
((ScrollView) findViewById(R.id.TableScroller)).fullScroll(View.FOCUS_DOWN);
// Enqueue the scrolling to happen after the new row has been layout
((ScrollView) findViewById(R.id.TableScroller)).post(new Runnable() {
public void run() {
((ScrollView) findViewById(R.id.TableScroller)).fullScroll(View.FOCUS_DOWN);
When a button is clicked, the following method is run:
public void createTableRow(View v) {
TableLayout tl = (TableLayout) findViewById(R.id.spreadsheet);
TableRow tr = new TableRow(this);
LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
tr.setLayoutParams(lp);
TextView tvLeft = new TextView(this);
tvLeft.setLayoutParams(lp);......................
R.id.spreadsheet is an xml TableLayout. I can see from debugging that the method is being accessed, but nothing is drawn to the screen. What gives? Do I need to reset the Content View somehow?
can I insert a new column into existing table. Because I had read somewhere that SQLite is limited on the ALTER TABLE command.

How to create a table without primary key but it has one autoincrement column.
View 2 Replies View RelatedSo I have an app on the market, and with an update I want to add some columns to the database. No problems so far. But I want to detect if the database in use is missing these columns, and add them if this is the case. I need this to be done dynamically and not just after the update to the new version, because the application is supposed to still be able to import older databases. Normally I would be able to use the PRAGMA query, but Im not sure how to do this with Android. I cant use execSQL since it is a query, and I cant figure out how to use PRAGMA with the query()-function.
Ofcourse I could just catch exceptions and then add the column, or always add the columns to each table before I start to work with it, but that is not a neat solution.
I have a table with column headings: | _id (long) | Name (String) | x (integer) | y (integer) |
I want to delete the row in the table that has Name myName.
// In onCreate
dbHelper = new DBAdapter(this);
dbHelper.open()
// Function in DBAdapter class
public boolean deleteTitleGivenName(String myName)
{return dbHelper.delete(DATABASE_TABLE_2, KEY_NAME + "=" + myName, null) > 0;}
// Function call in java code
dbHelper.deleteTitleGivenName(myName); // this is where my code fails
dbHelper.close();
Just as a note: myName is for sure in the database. Also, I can not use the ROWID since I am getting myName from a ListView.
I just started programming with Android and I have tried for days to solve this problem.
Is my WHERE clause correct (KEY_NAME + "=" + myName)?
I have a res/layout/main.xml including these elements and others:
<some.package.MyCustomView android:id="@+id/foo" (some other params) />
<TextView android:id="@+id/boring" (some other params) />
In my Activity's onCreate, I do this:
setContentView(R.layout.main);
(TextView) boring = findViewById(R.id.boring);
// ...find other elements...
MyCustomView foo = (MyCustomView) findViewById(R.id.foo);
if (foo == null) { Log.d(TAG, "epic fail"); }
The other elements are found successfully, but foo comes back null. MyCustomView has a constructor MyCustomView(Context c, AttributeSet a) and a Log.d(...) at the end of that constructor appears successfully in logcat just before the "epic fail".
findViewById() returns null for custom component in layout XML, not for other components. Why is foo null?
I have two files, one called "part1.txt" and another one called "part2.txt", which look like following
part1.txt part2.txt
lili like eating apple
lucy like playing football
Now i want to insert the contents of these two files into a single table with the schema
table_name(linefrompart1 varchar(100), linefrompart2 varchar(50))
My program reads the first file line by line and insert the data into the first column. But if it reads the second file and tries to insert the data line by line into the second column, it doesn't work the way i want. A table which i want should look like following
linefrompart1 linefrompart2
lili like eating apple
lucy like playing football
But instead i got the following table
linefrompart1 linefrompart2
lili null
lucy null
null like eating apple
null like playing football
Does somebody know how i can fix this problem?

I am on Android 2.1 and I have one multi column Custom listview Using BaseAdapter with an editable edittext at the end of the listview. If the data in the listview do not contain the data of user choice then user should be able to enter data. If the data is already there in the list user will be able to select the data using custom selector. If a selection is made in the list view and user wanted to enter data in the text field at the bottom after selection then the marker in the list view should be unselected. I tried to use onclick() method on edit text using click listener. First time when it is clicked, edit text is getting focus and onclick() method is not fired. And when it is clicked second time, onclick() method is fired and notifyDataSetChanged() method is called. I tried to call the notifyDataSetChanged() method from the Focus Listener, list view selection is gone in my first attempt and edit text is not receiving any data input from the keyboard (frozen).

I want to set up a table layout that scrolls like a spreadsheet. The top row of column headings should scroll horizontally but be pinned when scrolling vertically. The left-most column of row labels should scroll vertically but be pinned when scrolling horizontally. The number of rows and columns is not known in advance. Does anyone know of an example of this? Are there settings in TableLayout that can turn on this scroll behavior? Is there, perhaps, a more advanced widget than TableLayout that can produce this type of scrolling? Are there some tricks I can do with a ScrollView to get this behavior?
