How do I achieve a Facebook Messenger/ Google Hangouts like layout to preview selected items in search bar on ANDROID?

半腔热情 提交于 2019-11-30 22:25:24
Basically what I want to create can be best illustrated from a screenshot. I have a listview of people just like FB Messenger app. I want the ability for my users to have a search bar like the one shown in the screenshots. It should have the following properties: 1) Search bar should preview names of people selected in the list view 2) People can be de-selected by hitting backspace on any name in the preview search bar 3) The search bar should be able to filter the bottom list of people as the user types. I have a solution for propert 3) but I am clueless about the other two. Please HELP!!!

How can I prevent the cursor from resizing in an EditText (MultiAutoCompleteTextView) after I add an imagespan using a SpannableStringBuilder?

自作多情 提交于 2019-11-30 19:17:35
问题 Here is what it looks like in the beginning when I haven't added any imagespan chips - As you can tell there the cursor is placed at the right size and the gravity is respected. Then when I add an imagespan, the cursor all of a sudden becomes bigger like this - I don't understand why this happens and I also don't know how to fix it, i.e. keep the cursor the same size. Finally when I start typing again, the cursor is all wierd while maintaining the size of the of the font and the span also

Paragraph spacings using SpannableStringBuilder in TextView

空扰寡人 提交于 2019-11-30 14:30:30
As the question indicates, I am working on a TextView which will show formatted text using SpannableStringBuilder . It has multiple paragraphs and I would like to know what would be the easiest (or at least the least complicated) way to set spacing between paragraphs using some inbuilt span. Is this possible? Or will I be required to build a custom span class for this? Implement the LineHeightSpan and override chooseHeight method as follows @Override public void chooseHeight(CharSequence text, int start, int end, int spanstartv, int v, FontMetricsInt fm) { Spanned spanned = (Spanned) text; int

Why show java.lang.ClassCastException: android.text.SpannableString cannot be cast to java.lang.String?

When copying String from any browser page, pasteData works properly. However when copying SpannedString from a message sent item editor(field), the application crashes and shows this error message: java.lang.ClassCastException: android.text.SpannableString cannot be cast to java.lang.String My code: // since the clipboard contains plain text. ClipData.Item item = clipBoard.getPrimaryClip().getItemAt(0); // Gets the clipboard as text. String pasteData = new String(); pasteData = (String) item.getText(); where the ClipboardManager instance defined as clipBoard , below: clipBoard =

Creating softkeyboard with custom emoji

怎甘沉沦 提交于 2019-11-30 10:27:18
I have been tasked to create a new android 3rd party keyboard that supports customized emojis (My own Icons) from assets. I want to implement a softkeyboard with my own emoji icons without using UniCode or my custom UniCode. Questions: If I create a custom emoji, with some string of characters which does not map to the standard set of emojis, and text this message to a friend with the customized app/keyboard, what shows up on their device? The regular ASCII characters string? or the image. I have read two ways to add image to textView. Html.ImageGetter Spannable Image (String consisting of

How can I use onTouchListeners on each word in a TextView?

我怕爱的太早我们不能终老 提交于 2019-11-29 20:21:00
I would like to assign onTouchListeners to each word in a TextView. (Not to link to something on the internet, but just to continue the game logic inside the app). The general action of my game at this point is to see a TextView, touch a word, if it's the target word you win, else load another TextView based on the word you touch and repeat. The way I accomplish this now is with ClickableSpans and onClicks for each word. But I would rather have onTouchListeners so I can change the color of the background of the word on touch_down and do the game logic on touch_up, to make it look more

Is there any way to insert an ImageSpan in a TextView without disrupting the text?

早过忘川 提交于 2019-11-29 09:14:22
It seems that in order to add an ImageSpan to a Spannable in Android, I have to actually replace some text with the Image. For example: Spannable span = new SpannableString("Foo imageplace Bar!"); Drawable android = context.getResources().getDrawable(R.drawable.android); android.setBounds(0, 0, 32,32); ImageSpan image = new ImageSpan(android, ImageSpan.ALIGN_BASELINE); span.setSpan(image, 4, 14, Spannable.SPAN_INCLUSIVE_EXCLUSIVE); This will replace "imageplace" with the image. Because I'm dealing with complex multi-span text and reiteration, it's a bit of a headache to insert meaningless text

Most efficient way for Dynamic Text Color Change in TextView

对着背影说爱祢 提交于 2019-11-29 05:02:12
I want to change color of parts of a text several times with a timer. Simplest way is this: SpannableStringBuilder ssb = new SpannableStringBuilder(mainText); ForegroundColorSpan span = new ForegroundColorSpan(Color.BLUE); ssb.setSpan(span, start, end, 0); tv.setText(ssb); But if I run the above code several times in a second, I actually change the whole (large) text of TextView each time so a unwanted memory-CPU load will happen specifically on lower-end devices. How can I have a single Span on TextView and only change the Span start and end position? Will it work at all or a full text

How to loop through the spans in a SpannedString or SpannableString in Android
