I'm basicly going on this site: http://blog.velir.com/index.php/2010/11/17/android-snapping-horizontal-scroll/
But i'm having this problem:
Caused by: java.lang.IllegalStateException: HorizontalScrollView can host only one direct child "
on this line:
addView(internalWrapper);
Here is myHorizontalScrollView class:
public class MyHorizontalScrollView extends HorizontalScrollView {
int scrollToViewPos = 0;
public MyHorizontalScrollView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init(context);
}
public MyHorizontalScrollView(Context context, AttributeSet attrs) {
super(context, attrs);
init(context);
}
public MyHorizontalScrollView(Context context) {
super(context);
init(context);
}
void init(Context context) {
// remove the fading as the HSV looks better without it
setHorizontalFadingEdgeEnabled(false);
setVerticalFadingEdgeEnabled(false);
}
public void initViews(final MyHorizontalScrollView me, View[] children, int scrollToViewIdx, SizeCallback sizeCallback) {
LinearLayout internalWrapper = new LinearLayout(getContext());
internalWrapper.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
internalWrapper.setOrientation(LinearLayout.HORIZONTAL);
addView(internalWrapper);
final int w = me.getMeasuredWidth();
final int h = me.getMeasuredHeight();
sizeCallback.onGlobalLayout();
int[] dims = new int[2];
scrollToViewPos = 0;
for (int i = 0; i < children.length; i++) {
sizeCallback.getViewSize(i, w, h, dims);
internalWrapper.addView(children[i], dims[0], dims[1]);
if (i < scrollToViewIdx) {
scrollToViewPos += dims[0];
}
}
new Handler().post(new Runnable() {
public void run() {
me.scrollBy(scrollToViewPos, 0);
}
});
}
#Override
public boolean onTouchEvent(MotionEvent ev) {
// Allow touch events.
return true;

// Allow touch events.
return true;
}
public interface SizeCallback {
public void onGlobalLayout();
public void getViewSize(int idx, int w, int h, int[] dims);
}
}
MyHorizontalScrollView in xml:

You are missing addView(internalWrapper); that's why is not visible.

So I got this custom SwipeButton class from Git (com.ebanx.swipebtn.SwipeButton). Now I want to create an Object from SwipeButton with a layout looking like the one from the xml file. Is there any method, where I just can give the new button the prefinished layout without having to use all these Methods in the SwipeButton class? I am going to create the buttons dynamically later on, but all being the same layout. Help pls?
you forgot to add LayoutParams to your button
use below code before adding button into layout
button.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT))
and set your LinearLayout height wrap_content not 70dp
In this below code i want to set center_horizontal as attachmentSlidingLayer view id but layout_gravity and gravity for parent and child view doesn't work correctly and by default gravity is left side

I want to create a custom view which should be added in another custom view.
The second view will be a container, so it should be able to contain the first view as its child.
For creating this views I am extending ViewGroup & LinearLayout classes.
Child view class is NodeView
public class NodeView extends LinearLayout
{
private final static String TAG = "NodeView";
private ImageView ivTop;
private ImageView ivBottom;
private Context myContext;
public NodeView(Context context, AttributeSet attrs)
{
super(context, attrs);
this.myContext = context;
setOrientation(LinearLayout.VERTICAL);
setGravity(Gravity.CENTER);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.view_test_multi, this, true);
ivTop = (ImageView) getChildAt(0);
ivBottom = (ImageView) getChildAt(2);
ivTop.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
Toast.makeText(myContext, "Top Clicked", Toast.LENGTH_SHORT).show();
}
});
ivBottom.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
Toast.makeText(myContext, "Bottom Clicked", Toast.LENGTH_SHORT).show();
}
});
}
#Override
protected void onDraw(Canvas canvas)
{
super.onDraw(canvas);
}
public NodeView(Context context)
{
this(context, null);
}
}
& the container class is TreeViewGroup
public class TreeViewGroup extends ViewGroup
{
private static final String TAG = "CustomTreeNodeView";
NodeView nodeView;
public TreeViewGroup(Context context, AttributeSet attrs, int defStyleAttr)
{
super(context, attrs, defStyleAttr);
nodeView = new NodeView(getContext());
addView(nodeView);
}
public TreeViewGroup(Context context, AttributeSet attrs)
{
this(context, attrs, 0);
}
public TreeViewGroup(Context context)
{
this(context, null, 0);
}
#Override
protected void onDraw(Canvas canvas)
{
super.onDraw(canvas);
}
#Override
protected void onLayout(boolean changed, int l, int t, int r, int b)
{
}
}
& xml layout for node view is view_test_multi.xml
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android" >
<ImageView
android:layout_width="15dp"
android:layout_height="15dp"

<ImageView
android:layout_width="15dp"
android:layout_height="15dp"
android:layout_centerVertical="true"
android:src="#drawable/point_grey" />
</merge>
My activity's layout is activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="#+id/activity_main_custom_tree_node_view"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
MainActivity class is
**public class MainActivity extends Activity
{
TreeViewGroup treeNodeView;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
treeNodeView = (TreeViewGroup) findViewById(R.id.activity_main_custom_tree_node_view);
}
}**
When I run the app I don't see the NodeView added in main View. Am I doing the right thing if not please tell me how can I make it working?
To create a custom ViewGroup, the only method you need to override is
onLayout. The onLayout is triggered after the ViewGroup itself has
finished laying itself out inside its own container ViewGroup and is
now responsible for laying out its children. It should call the layout
method on all of its children to now position and size them (the left
and top parameters will determine the child view’s x and y and the
right and bottom will determine its width (right – left) and height
(top-bottom).
So your TreeViewGroup code will look like :
#Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
int count = getChildCount();
for (int i = 0; i < count; i++) {
View child = getChildAt(i);
if (child.getVisibility() != GONE) {
ViewGroup.LayoutParams lp = (ViewGroup.LayoutParams) child
.getLayoutParams();
int childLeft = 0;
int childTop = 0;
child.layout(childLeft, childTop,
childLeft + child.getMeasuredWidth(),
childTop + child.getMeasuredHeight());
}
}
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
measureChildren(widthMeasureSpec, heightMeasureSpec);
int measuredWidth = 200; // Calculate the height
int measuredHeight = 200; // Calculate the width
setMeasuredDimension(measuredWidth, measuredHeight);
}
Refer this link http://arpitonline.com/2012/07/01/creating-custom-layouts-for-android/
What I am trying to achieve:
measure a container View in my layout, mainContainer, that is defined in the XML
pass the mainContainer's width and height to a different custom View before onDraw() is called
I want to pass the width and height so the custom View knows where to draw canvas.drawBitmap using coordinates
The custom view will be programmatically created from code
How can I pass the measured int width and int height to my custom View before onDraw() is called?
Custom View
public class AvatarView extends ImageView {
private Bitmap body;

public AvatarView(Context context) {
super(context);

What you need to do is add a flag inside your AvatarView that checks if are you going to render this or not in your onDraw method.
sample:
public class AvatarView extends ImageView {
private Bitmap body;
private Bitmap hat;
private int containerHeight;
private int containerWidth;
private boolean isRender = false;
public AvatarView(Context context) {
super(context);
init();
}
public AvatarView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public AvatarView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public void setMeasure(int containerWidth, int containerHeight )
{
this.containerHeight = containerHeight;
this.containerWidth = containerWidth;
}
private void init() {
body = BitmapFactory.decodeResource(getResources(), R.drawable.battle_run_char);
hat = BitmapFactory.decodeResource(getResources(), R.drawable.red_cartoon_hat);
}
public void setRender(boolean render)
{
isRender = render;
}
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
if(isRender )
{
canvas.drawBitmap(body, x, y, null);
canvas.drawBitmap(hat, x, y, null);
}
}
}
Now it wont render when you dont call setRender and set it to true. And just call setMeasure to pass the value.
First you need to call setMeasure and after you set the measure you then call setRender(true) and call invalidate() to call the onDraw method to render the images
This is my extended View:
public class PieMenu extends FrameLayout{
private View _view;
private ArrayList<PieItem> mItems;
private Context _context;
public PieMenu(View view, Context context) {
super(context);
_context = context;
_view = view;
setWillNotDraw(false);
// TODO Auto-generated constructor stub
}
public void addPieMenu(int x, int y){
mItems = new ArrayList<PieItem>();
Path path = new Path();
path.addCircle(9, 9, 9, Path.Direction.CW);
PieItem item = new PieItem(_view,_context,path, x,y,40);
mItems.add(item);
//FrameLayout.LayoutParams lyp = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT);
//pieView.setLayoutParams(lyp);
//addView(pieView);
// animateIn();
invalidate();
}
#Override
protected void onDraw(Canvas canvas) {
Paint paint1 = new Paint();
paint1.setColor(Color.RED);
canvas.drawCircle(50, 50, 25, paint1);
this.draw(canvas);
//_view.draw(canvas);
}
}
This is my main activity:
public class MainActivity extends Activity {
PieMenu pieMenu;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pieMenu = new PieMenu(getWindow().getDecorView().findViewById(android.R.id.content) ,MainActivity.this);
FrameLayout fl = (FrameLayout)findViewById(R.id.flayout);
fl.addView(pieMenu);
}
#Override
public boolean onTouchEvent(MotionEvent event) {
int x = (int)event.getX();
int y = (int)event.getY();
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
{
pieMenu.addPieMenu(x,y);
}
case MotionEvent.ACTION_MOVE:
case MotionEvent.ACTION_UP:
}
return false;
}
}
This is my main activity.xml:

When I compile this, the app crashes with this error:
07-20 21:38:45.906: E/AndroidRuntime(10088): Caused by: java.lang.NoSuchMethodException: <init> [class android.content.Context, interface android.util.AttributeSet]
Where am I going wrong?
You will need these constructors in your PieMenu class:
public PieMenu(View view, Context context) {
super(context);
// ~
}
public PieMenu(View view, Context context, AttributeSet attrs) {
super(context, attrs);
// ~
}
Edit 1
public PieMenu(View view, Context context, AttributeSet attrs, int style) {
super(context, attrs, style);
// ~
}
