Android :: SQLite For Android Custom Table View (SQL VIEW) Discrepancy?

Jul 16, 2010

I've created a custom view in an SQLite database for an Android application. I'm using Sqliteman on Ubuntu to test my SQL statements before I put them in my app. I'm trying to do a simple select statement on my view. The select statement works fine in SQLiteman but when I put the same statement in my code it throws an error. The statement: select * from item_view where parent_item_id = 0;........

Android :: Custom View Extending View-Class / Still Based On XML-Layout

Aug 17, 2010

I want to build my own custom view which should look like the Crysis-GUI.At first I designed a XML-based Layout and made it visible via the setContentView(int resid)-Method. Worked pretty well.But now I wan't to go a step further and draw in my Layout. So I created a new Class, let it extend View and overrode the onDraw()-Method. So far so good.But how can I still use my XML-Layout? I can't do setContentView anymore, so how could the same effect be achieved?

Android :: Multi Column Custom List View / With Editable Edit Text At End Of List View

Nov 3, 2010

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).

Android :: Populate View Flipper Child View With List View?

Aug 2, 2010

I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:

The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............

Android :: Scroll To Last Line Of Table Layout Within Scroll View

Jun 21, 2010

I 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);

But I want to nest my keyboard with a TextView so I'd like to be able to do

Android :: Custom View Not Appearing?

When I comment out setContentView(boardView); in my Game.java my custom view in BoardView works fine and displays everything nicely... but onSizeChanged never gets called in BoardView.java... so I can't read the device width and height at runtime. If I leave setContentView uncommented onSizeChanged works... but the screen is blank!

Android :: Button In Custom View?

Apr 5, 2009

I'm trying to create a button in a custom view that I've created. I'm looping through an XML document and drawing certain things. I want to be able to also create buttons to go in certain locations depending on the xml data. I'd like to do it in the view because I want to be able to call invalidate() on my view to redraw things and replace the buttons when new xml data is available.

The problem is that I put my code in the view class, the activity crashes because the button is "null".

Here is a subset of my code:

CODE:............

I know this code works for creating buttons because I can put it in my activity class and it works just fine. Any suggestions? I thought about relocating the button in the activity, but I can't figure out how to do this when new data is available.

Android :: Custom Checkable View?

Nov 5, 2010

I'm writing a little custom view which can be in two states : checked, not checked. According to the state it is in, it's background changes. Quite straightforward sort of behavior. My class extends FrameLayout and implements the Checkable interface.

In my toogle method I just calls the setChecked method with a boolean corresponding to the new state. My setChecked method simply sets a mChecked boolean and calls the refreshDrawableState method. Pressing the view should then toggle it back and forth between the states check, unchecked.

The background of the FrameLayout is given a StateListDrawable in which I've defined a drawable item for the following states: state_pressed, state_focused, state_checked=true, state_checked=false.

When I press my custom view, the background changes all right back and forth between the state_pressed=true and state_checked=false items. But state_checked=true is never called.

I am trying to do is to embed a custom view in the default layout main.xml:

CODE:......

As you can see the class is called com.lam.customview.CustomDisplayView, with the id of custom_display_view1. now in the com.lam.customview.CustomDisplayView class, i want to use another layout called custom_display_view.xml because i don't want to programmatically create controls/widgets.

Custom_display_view.xml is just a button and an image, the content of which i want to change based on certain conditions:

CODE:..............

I tried to do:

1)
CODE:........

But got this error, "03-08 20:33:15.711: ERROR/onCreate(10879): Binary XML file line #8: Error inflating class java.lang.reflect.Constructor ".

2)
CODE:..........

But got this error, "03-08 20:28:47.401: ERROR/CustomDisplayView(10806): Resource ID #0x7f050002 type #0x12 is not valid "

Also, if i do it this way, as someone has suggested, it's not clear to me how the custom_display_view.xml is associated with the custom view class.

I also have a custom View defined within my Activity...

Some how, I need these linked together so that the 'third_view' defined in the XML layout file needs to be a CompassView, or have a CompassView added to it.

What I can do is drop the 'third_view' from the layout and then add in the CompassView manually..

CODE:........

But then I lose the ability to define other view controls within the layout file.

Can I add CompassView to 'third_view' declaratively?
