Yes, you have to extend DrawerLayout and override some methods because MIN_DRAWER_MARGIN is private
Code:
public class FullDrawerLayout extends DrawerLayout {
private static final int MIN_DRAWER_MARGIN = 0; // dp
public FullDrawerLayout(Context context) {
super(context);
}
public FullDrawerLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public FullDrawerLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
final int widthMode = MeasureSpec.getMode(widthMeasureSpec);
final int heightMode = MeasureSpec.getMode(heightMeasureSpec);
final int widthSize = MeasureSpec.getSize(widthMeasureSpec);
final int heightSize = MeasureSpec.getSize(heightMeasureSpec);
if (widthMode != MeasureSpec.EXACTLY || heightMode != MeasureSpec.EXACTLY) {
throw new IllegalArgumentException(
"DrawerLayout must be measured with MeasureSpec.EXACTLY.");
}
setMeasuredDimension(widthSize, heightSize);
// Gravity value for each drawer we've seen. Only one of each permitted.
int foundDrawers = 0;
final int childCount = getChildCount();
for (int i = 0; i < childCount; i++) {
final View child = getChildAt(i);
if (child.getVisibility() == GONE) {
continue;
}
final LayoutParams lp = (LayoutParams) child.getLayoutParams();
if (isContentView(child)) {
// Content views get measured at exactly the layout's size.
final int contentWidthSpec = MeasureSpec.makeMeasureSpec(
widthSize - lp.leftMargin - lp.rightMargin, MeasureSpec.EXACTLY);
final int contentHeightSpec = MeasureSpec.makeMeasureSpec(
heightSize - lp.topMargin - lp.bottomMargin, MeasureSpec.EXACTLY);
child.measure(contentWidthSpec, contentHeightSpec);
} else if (isDrawerView(child)) {
final int childGravity =
getDrawerViewGravity(child) & Gravity.HORIZONTAL_GRAVITY_MASK;
if ((foundDrawers & childGravity) != 0) {
throw new IllegalStateException("Child drawer has absolute gravity " +
gravityToString(childGravity) + " but this already has a " +
"drawer view along that edge");
}
final int drawerWidthSpec = getChildMeasureSpec(widthMeasureSpec,
MIN_DRAWER_MARGIN + lp.leftMargin + lp.rightMargin,
lp.width);
final int drawerHeightSpec = getChildMeasureSpec(heightMeasureSpec,
lp.topMargin + lp.bottomMargin,
lp.height);
child.measure(drawerWidthSpec, drawerHeightSpec);
} else {
throw new IllegalStateException("Child " + child + " at index " + i +
" does not have a valid layout_gravity - must be Gravity.LEFT, " +
"Gravity.RIGHT or Gravity.NO_GRAVITY");
}
}
}
boolean isContentView(View child) {
return ((LayoutParams) child.getLayoutParams()).gravity == Gravity.NO_GRAVITY;
}
boolean isDrawerView(View child) {
final int gravity = ((LayoutParams) child.getLayoutParams()).gravity;
final int absGravity = Gravity.getAbsoluteGravity(gravity,
child.getLayoutDirection());
return (absGravity & (Gravity.LEFT | Gravity.RIGHT)) != 0;
}
int getDrawerViewGravity(View drawerView) {
final int gravity = ((LayoutParams) drawerView.getLayoutParams()).gravity;
return Gravity.getAbsoluteGravity(gravity, drawerView.getLayoutDirection());
}
static String gravityToString(int gravity) {
if ((gravity & Gravity.LEFT) == Gravity.LEFT) {
return "LEFT";
}
if ((gravity & Gravity.RIGHT) == Gravity.RIGHT) {
return "RIGHT";
}
return Integer.toHexString(gravity);
}
}

[Q] How to stop the ball at touch release

hi, its killing me i can't fix it i made this thing because i was learning Canvas and drawing on android !
i included moving animations (smooth) but i removed it
Code:
package com.example.graphics;
import android.content.Context;
import android.view.KeyEvent;
import android.view.MotionEvent;

}
// Called back when the view is first created or its size changes.
@Override
public void onSizeChanged(int w, int h, int oldW, int oldH) {
// Set the movement bounds for the ball
xMax = w-1;
yMax = h-1;
}
}
the problem is my ball doesn't move at all, but i see the line, once i remove the line:
Code:
case MotionEvent.ACTION_UP:
ballSpeedX = 0;
ballSpeedY = 0;
it works, but you know, after release it continues with same speed :! its like the ACTION_UP is always the case, !!! any idea why it doesn't work, how to stop the ball once the user releases the screen?

also sorry if this is not the right place. i searched the forums, i got confused i didn't find anyplace to ask this question so i tough this is the best place!

Share Action Provider is unresponsive

i want to share a layout as an image. code listed below is working fine for the save action button but not for share action button. share action button remains unresponsive. i am unable to figure it out what is wrong.
Code:
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.eid_card_final, menu);
MenuItem item = menu.findItem(R.id.action_share);
myshare = (ShareActionProvider)item.getActionProvider();
String sharestate = Environment.getExternalStorageState();
RelativeLayout rlShareLayout = (RelativeLayout)findViewById(R.id.relativeLayout);
Bitmap sharebitmap = Bitmap.createBitmap(rlShareLayout.getWidth(), rlShareLayout.getHeight(), Bitmap.Config.ARGB_8888);
Canvas sharecanvas = new Canvas(sharebitmap);
rlShareLayout.draw(sharecanvas);
try{
if (Environment.MEDIA_MOUNTED.equals(sharestate)) {
Random sharerand = new Random();
int sharerandnum = sharerand.nextInt(1000);
String sharefilename = sharerandnum + ".jpeg";
sharef = new File(getExternalFilesDir(null),sharefilename);
FileOutputStream shareout = new FileOutputStream(sharef);
boolean success = sharebitmap.compress(CompressFormat.PNG, 100, shareout);
}
} catch (Exception e) {
e.printStackTrace();
}
Intent shareintent = new Intent(Intent.ACTION_SEND);
shareintent.setType("image/*");
Uri shareuri = Uri.fromFile(sharef);
shareintent.putExtra(Intent.EXTRA_STREAM, shareuri.toString());
shareintent.setData(shareuri);
myshare.setShareIntent(shareintent);
return true;
}

[Q] Button MaskFilter?

Hi,
I'm trying to apply a Mask or Blur Filter to some buttons at runtime... This button is reflecting a "layer" object, so I'd like to blur its edges to reflect how transparent is this layer...
I'm able to set a ColorFilter, or apply a maskFIlter to its TextView, but cant figure how to apply a maskFilter to the whole button...
here is the part of my code where I'd like to apply this filter (in a applyFilter method):
Code:
public void createList(LinearLayout lm) {
lm.removeAllViews();
for (int i = 0; i < kwang07Android.nblayers; i++) {
final Button newbtn = new Button(this, null, android.R.attr.buttonStyleSmall);
int col = kwang07Android.layers[i].col;
int newColor = Color.argb(156+(int)(kwang07Android.layers[i].opacite*100), Color.red(col), Color.green(col), Color.blue(col));
newbtn.getBackground().setColorFilter(newColor, MULTIPLY);
[COLOR="DarkOrange"]//applyFilter(newbtn, i, BlurMaskFilter.Blur.INNER);[/COLOR]
newbtn.setText("couche " + Integer.toString(i));
newbtn.setId(i);
newbtn.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,30+kwang07Android.layers[i].thickness/20));
final int finalI = i;
newbtn.setOnTouchListener(new Button.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
showColorPickerDialogDemo(newbtn, finalI);
}
return false;
}
});
lm.addView(newbtn);
}
...
Any advice?
Thanks.

How to draw or erase on a photo loaded onto a Imageview?

As what was stated on the header I want to implement either a "paint" function for user to edit paint/censor unwanted parts of a photo displayed on a imageview before uploading it to a server in the edited format and a redo function if user makes a mistake while editing?
How do I come about doing it, I've read relevant topics on Canvas, or FingerPaint but still puzzled on how to implement it based on my project here? Tried referencing to the links here and here but without success in implementing the codes into my project code due to my lack of programming skills.
Thanks for any help rendered!
Tried integrating the codes below into my code above (image preview after taking a photo with the camera) for user to start editing via painting but still not working? Thanks for any help rendered!
