How can i create a description within a scrollview?
i would like to place a date on none line and a title on a separate line, but even with spaces and pressing enter it creates all on one line.
The code works well i just need help on being able to control what i write on what line. For example
date
location
title
expiry
instead of writing them on separate lines it all goes onto the same line. Even using enter, tab, spaces.
MAIN ACTIVITY
TextView mTitleWindow = (TextView) findViewById(R.id.titleWindow);
TextView mMessageWindow = (TextView) findViewById(R.id.messageWindow);
mTitleWindow.setText("BATMAN IS PART OF THE DC TRINITY");
StringBuilder stringBuilder = new StringBuilder();
String someMessage = "hello hi" ;
stringBuilder.append(someMessage);
mMessageWindow.setText(stringBuilder.toString());

I have some problem with ellipsize in TextView.
Here is html string:
final String str = "His followed carriage proposal entrance <br/>directly had elegance. Greater for cottage gay parties natural. Remaining he furniture on he discourse suspected perpetual. <br/>Power dried her taken place day ought the. Four and our ham west miss."
I create 2 textview(tv_test_html, tv_test_normal).
<TextView
android:id="#+id/tv_test_html"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:maxLines="3"
android:ellipsize="end"
android:text="Hello"
/>
<TextView
android:layout_marginTop="20dp"
android:id="#+id/tv_test_normal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:maxLines="3"
android:ellipsize="end"
android:text="Hello"
/>
In code I set:
final TextView tvTestHtml = (TextView) findViewById(R.id.tv_test_html);
final TextView tvTestNormal = (TextView) findViewById(R.id.tv_test_normal);
tvTestHtml.setText(Html.fromHtml(str));
tvTestNormal.setText(str);
When I run application:
You can see "..." is error when I use Html.fromHtml(...);
So how do I fix it ?
Thanks in advance !
[I just update image]
replace string with it : His followed carriage proposal entrance <br>directly had elegance. Greater for cottage gay parties natural. Remaining he furniture on he discourse suspected perpetual. <br>Power dried her taken place day ought the. Four and our ham west miss.
This is driving me absolutely crazy and Im not sure what is going on.
I have an xml layout with a TextView within a clickable RelativeLayout.
<RelativeLayout
android:id="#+id/bg_section"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="10dp"
android:background="#color/almost_black"
android:clickable="true"
android:onClick="goToBG"
android:padding="10dp" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:text="Go To B.G."
android:textColor="#color/white"
android:textSize="20sp" />
<ImageView
android:id="#+id/bg_arrow"
android:layout_width="wrap_content"
android:layout_height="30dp"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="-10dp"
android:src="#drawable/arrow_icon" />
<TextView
android:id="#+id/current_bg_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toLeftOf="#id/bg_arrow"
android:text="3"
android:textColor="#color/holo_blue"
android:textSize="22sp" />
</RelativeLayout>
Now in my code I try to update the textview "current_bg_count"
private void updateBGCount(){
try{
RelativeLayout bgSection = (RelativeLayout) findViewById(R.id.bg_section);
TextView bgCountTV = (TextView) bgSection.getChildAt(2);
bgCountTV.setText(tempBG.size());
}
catch(Exception e){
e.printStackTrace();
Logger.d(TAG, "exception in updateBGCount");
}
}
This gives a ResourceNotFountException on the line where I setText although the RelativeLayout is found without a problem. Even when I try finding it just by id like this:
TextView bgCountTV = (TextView) findViewById(R.id.current_bg_count)
bgCountTV.setText(tempBG.size());
it gives the same error.
All the other views in the layout are found easily and updated just fine. Only this one TextView is giving me the problem. Does anyone have any idea what the problem is?
You need to convert your size of the ArrayList to a String at this line
setText(tempBG.size())
Since tempBG.size() returns an int then setText() is looking for a resource with the id of whatever that returns. You are using this setText(ResId int) method which is used for if you have a string resource that you want to use to set the text.
So change it to
setText(String.valueOf(tempBG.size()));
Try setting your tempBG.size() to string like this
bgCountTV.setText(""+tempBG.size());
This should work
Are you using eclipse? Check there is no errors and warning in your project. Sometimes there are errors in xml that let you compile, but doesn't work properly.
the Problem is with this code
bgCountTV.setText(tempBG.size());
tempBG.size() this code is returning an int value which it is assuming as string Resource id something like R.string.VARIABLE_NAME coz it have a corresponding int value which TextView is assuming as id
What you can do
bgCountTV.setText(tempBG.size()+"");
OR
bgCountTV.setText(String.ValueOf(tempBG.size()));
OR
bgCountTV.setText(tempBG.size().toString());
I have to develop one android example.
Here i have to pass the html string value and set the value on textview.
i have used below code:
<TextView
android:id="#+id/title1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Title"
android:layout_below="#+id/youtube_view"
/>
In android code:
String fullcontent = in.getStringExtra("FullContent");
full_content = fullcontent.substring(1);
lblContent = (TextView) findViewById(R.id.title1);
lblContent.setText(Html.fromHtml(full_content),TextView.BufferType.SPANNABLE);
lblContent.setMovementMethod(LinkMovementMethod.getInstance());
Here i have to run the app which means the textview is clickable...how can i disable the textview clickable...
I saw this source as layout of AlertDialog in res\layout folder of Android SDK:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout android:id="#+id/body"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:baselineAligned="false"
android:paddingLeft="8dip"
android:paddingTop="10dip"
android:paddingRight="8dip"
android:paddingBottom="10dip">
<ProgressBar android:id="#android:id/progress"
style="#android:style/Widget.ProgressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:max="10000"
android:layout_marginRight="12dip" />
<TextView android:id="#+id/message"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
</LinearLayout>
</FrameLayout>
I tried to find TextView that it's id is "message" like this:
TextView tvMessage = (TextView)dialog.findViewById(android.R.id.message);
It works fine.Then I tried to find LinearLayout that it's id is "body" like this:
LinearLayout body = (LinearLayout)dialog.findViewById(android.R.id.body);
But eclipse show this error:
body cannot be resolved or is not a field
This is snippet code:
ProgressDialog dialog = new ProgressDialog(WriteOpinionActivity.this);
dialog.setMessage("some text");
dialog.show();
TextView tvMessage = (TextView)dialog.findViewById(android.R.id.message);
LinearLayout body = (LinearLayout)dialog.findViewById(android.R.id.body);
Why this error occurs and how I can reach "body"?
Basically, not all resources are accessible to You from platforms res folder.
E.g. I'm able to find #+id/message in global_actions_item.xml, usb_storage_activity.xml, alert_dialog_holo.xml, js_prompt.xml, progress_dialog_holo.xml, progress_dialog.xml, alert_dialog.xml (for API 17), and so, there's no warranty that You get id which defined in progress_dialog.xml (it can be defined in another file and just because of the same name You is able to find it in progress dialog).
Actually, public resources are defined here, however, it looks quite outdated, so some resources might be missed. Checkout these questions about lists of all accessible resources: 1 and 2
Use this instead.
TextView tvMessage = (TextView)dialog.findViewById(R.id.message);
LinearLayout body = (LinearLayout)dialog.findViewById(R.id.body);
You weren't actually using android.R.id.message in the first place. #+id/message means you are creating a new id resource named message.
To use an id that exists in the Android framework, you can see here that you use #android:id/progress. And in source, you use it like you had it: android.R.id.progress.
Otherwise, use android:id="#=id/myIdentifier" in XML and
findViewById(R.id.myIdentifier) in code.

I'm building a new InfoWindow (google maps api v2) and I'm trying to get my layout to be perfect.
A part of that layout is this:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/txtInfoWindowName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:ellipsize="end"
android:singleLine="true"
android:textColor="#ff000000"
android:textSize="14dp"
android:textStyle="bold"/>
<TextView
android:id="#+id/txtInfoWindowObstacles"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:maxLength="32"
android:lines="1"
android:singleLine="true"
android:textColor="#ff7f7f7f"
android:textSize="14dp"/>
Now, the problem is with the android:ellipsize="end".
It should draw the three dots at the end but it doesn't do that.
Now I'm getting something like this:
TextTextTextTextTe
Instead of this:
TextTextTextTextTe...
I'm thinking it has something to do with the fact that I'm using layout_width="wrap_content" . But I need that because I'm using a LinearLayout
I tried your code and they work fine, except the second TextView which has the attribute android:maxLength="32", which in this case the text cannot be ellipsized because of 32 characters limit. But if you remove it, it works as expected.
There is another option - you can format your string from code like this:
private static final int STR_MAX_CHAR_COUNT = 32;
private String formatString(String stringToFormat) {
if(stringToFormat.length() > STR_MAX_CHAR_COUNT){
stringToFormat = stringToFormat.substring(0, STR_MAX_CHAR_COUNT - 1) + "...";
}
return stringToFormat;
}
And then just set string like this:
String newText = "some long-long text";
mTextView.setText(formatString(newText))
