How can I used TextToSpeech on textView with multiple LinearLayout ?
I' trying to add TTS method on emails to read it, so I worked on mail client from open source and started to add the TTS code inside it, so when the button is clicked,the message should be read out loud
this is what I do:
the name of activity class is MessageContainerView
unsignedText = (TextView) findViewById(R.id.message_unsigned_text);
buttonRead =(Button)findViewById(R.id.button);
t1=new TextToSpeech(activity.getApplicationContext(), new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if(status != TextToSpeech.ERROR) {
t1.setLanguage(Locale.UK);
}
}
});
buttonRead.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String toSpeak = unsignedText.getText().toString();
Toast.makeText(activity.getApplicationContext(), toSpeak,Toast.LENGTH_SHORT).show();
t1.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);
}
});
but when I clicked the button,the app stopped
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"

</com.fsck.k9.ui.messageview.MessageContainerView>
Is that because a multiple LinearLayout? so the TTS code doesn't reach to text inside TextView?
Text to speech for multiple text one by one.try this
private void speakOut () {
String que = tvone.getText().toString();
String op1 = tvtwo.getText().toString();
String op2 = tvthree.getText().toString();
String op3 = tvfoure.getText().toString();
String op4 = tvfive.getText().toString();
tts.speak(que, TextToSpeech.QUEUE_ADD, null);
tts.speak(op1, TextToSpeech.QUEUE_ADD, null);
tts.speak(op2, TextToSpeech.QUEUE_ADD, null);
tts.speak(op3, TextToSpeech.QUEUE_ADD, null);
tts.speak(op4, TextToSpeech.QUEUE_ADD, null);
}

I am working on an android project, in which I need to set ImageView
background (ascending icon and descending icon) multiple times. to do
this I am doing it with a clicking variable like:
sortBookedOnLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
pickUpImage.setBackgroundResource(R.drawable.ascending);
vouchredImage.setBackgroundResource(R.drawable.ascending);
cancledImage.setBackgroundResource(R.drawable.ascending);
if(Constant.bookedOn == 1) {
Log.d(TAG, "FliteronClick:1 ");
bookedonImage.setImageDrawable(mContext.getResources().getDrawable(R.drawable.ascending_active));
// int ascending_active_b = R.drawable.ascending_active;
// bookedonImage.setBackgroundResource(ascending_active_b);
// bookedonImage.setImageDrawable(mContext.getResources().getDrawable( R.drawable.ascending_active));
// bookedonImage.setBackground(mContext.getResources().getDrawable(R.drawable.ascending_active));
// ivPickUpTxt.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.ascending_active, 0);
Constant.bookedOn = 2;
}else if(Constant.bookedOn == 2){
Log.d(TAG, "FliteronClick:2 ");
bookedonImage.setImageDrawable(mContext.getResources().getDrawable(R.drawable.decending_active));
// bookedonImage.setImageResource(android.R.color.transparent);
// int decending_active_b = R.drawable.decending_active;
// bookedonImage.setBackgroundResource(decending_active_b);
// bookedonImage.setImageDrawable(mContext.getResources().getDrawable( R.drawable.decending_active));
// ivPickUpTxt.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.decending_active, 0);
Constant.bookedOn = 1;
}
}
}
});
And My Xml layout is just like:
<LinearLayout
android:id="#+id/sortBookedOnLayout"
android:orientation="horizontal"
android:background="#color/white"
android:weightSum="2"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_weight="1.8"
android:layout_width="0dp"
android:layout_height="match_parent">
<RelativeLayout

android:layout_width="wrap_content"
android:layout_height="wrap_content">

android:layout_width="wrap_content"

android:drawablePadding="10dp"
android:hint="#string/booked_on"

android:maxLines="1"
android:padding="10dp"

</RelativeLayout>
</LinearLayout>
<LinearLayout
android:layout_weight=".2"
android:layout_width="0dp"
android:layout_height="match_parent">
<ImageView
android:id="#+id/booedOnImage"
android:scaleType="fitXY"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/ascending"
/>
</LinearLayout>
</LinearLayout>
Screenshot of my layout.
in this image i am going to click on BookedOn layout.
And my targetSdkVersion 25
I have tried it multiple ways as I commented but image icon is not
reflecting on imageView. any help will be appreciable.Thanks.
Try this:
qImageView.setBackgroundResource(R.drawable.thumbs_down);
and add android:scaleType:fitxy
<ImageView
android:id="#+id/booedOnImage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitxy"
android:background="#drawable/ascending"/>
(or) Try programmatically
imgview.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
Here's a thread that talks about the differences between the two methods.
I Understand your problem...You are not set the width of the LinearLayout
<LinearLayout
android:layout_weight=".2"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent">
<ImageView
android:id="#+id/booedOnImage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/abc_btn_rating_star_off_mtrl_alpha"
/>
</LinearLayout>
frist my english skill weak.

this is list view.
ㅡㅡㅡㅡㅡㅡㅡㅡ
ㅣㅡㅡㅡㅡㅡㅣㅢ <-- this is button , i init set invisible
ㅣㅡㅡㅡㅡㅡㅣㅢ
ㅣㅡㅡㅡㅡㅡㅣㅢ
ㅣㅡㅡㅡㅡㅡㅣㅢ
ㅣㅡㅡㅡㅡㅡ ////// <-- i want make visible button
ㅣㅡㅡㅡㅡㅡ ////// <-- specific position
I make the custom ListView
ListView row contains texts, Button.
The Button is set invisible option in xml file.
then, I want set the visible specific row button.
I tried that and failed
after make ArrayList for ListView, marking matching position like this
for(i=0; i<arraylist.size(); i++){
int t41=Integer.parseInt(arraylist.get(i).getm());
if(month == t41){
confirm_replay[i]=true;
temp55=i;
}
}
I can set the textValue. through adapter.getItem(int position).
but i don't know, how to control specific button.
also try add button into adapter. failed..
also search question in google but my eng skill bad. failed
add my code.

}
If you want to adjust a specific row, you can use the position parameter in your getView() method in adapter. For instance;
if(position==55){
holder.m.setVisibility(View.GONE);
}
I'm not sure i understand your question.
If i'm right you juste want your button to be invisble for specific row. To do so add the specific line at the end of your getView method
yourButton.setVisibility(View.INVISIBLE)
If you want to hide the entire row, the best way will probably be to change your adapter to diplay only row with content.
before setting the values to the view check the condition whatever you want like:-
if condition is true then set your view visible
else set your view invisible
if(true){
button.setVisibility(View.VISIBLE);
}else{
button.setVisibility(View.GONE);
}
I am using Vuforia AR sdk and want to create a button on the camera preview on the screen.
I cannot figure out where and how to add the button.
I have edit the camera_overlay_udt.xml like this.. In my layout design i have placed back button and listview.

};
loadingDialogHandler.captureButtonContainer = mUILayouts
.findViewById(R.id.camera_button);
mUILayouts.bringToFront();
}
They showing there layouts using handlers
Start you camera preview in a normal way. Place a layout on top of it with transparent background like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:background="#ff000000"
android:layout_height="match_parent">
<ImageView
android:id="#+id/start_image_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="5dp"
android:scaleType="fitXY"
android:layout_weight="1"
android:src="#drawable/scan_image"/>
</RelativeLayout>
In java file, you can add this layout like this:
private View mStartupView;
mStartupView = getLayoutInflater().inflate(
R.layout.startup_screen, null);
// Add it to the content view:
addContentView(mStartupView, new LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT));
This way you will get to see your button on top of camera preview. Hope it helps
You can add buttons in cameraoverlay layout which is in layout folder and you can initialize buttons in initAR function which is in mainactivity.
Step 1: Add the button in the camera_overlay.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/camera_overlay_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ProgressBar
style="#android:style/Widget.ProgressBar"
android:id="#+id/loading_indicator"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="18dp"
android:layout_marginTop="51dp"
android:text="Button" />
</RelativeLayout>
Step 2: Edit the ImageTargets.java class
private static final String LOGTAG = "ImageTargets";
private Button b1;
Step 3: Modify the initApplicationAR() function of ImageTargets.java class
private void initApplicationAR()
{
// Create OpenGL ES view:
int depthSize = 16;
int stencilSize = 0;
boolean translucent = Vuforia.requiresAlpha();
mGlView = new SampleApplicationGLView(this);
mGlView.init(translucent, depthSize, stencilSize);
mRenderer = new ImageTargetRenderer(this, vuforiaAppSession);
mRenderer.setTextures(mTextures);
mGlView.setRenderer(mRenderer);
b1 = (Button) findViewById(R.id.button1);
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
b1.setVisibility(View.GONE);
}
});
}
Now lay back and watch your button disappear on a click!
Although it's a long time since the post.. yet I found one article.. wherein you can have the desired thing..
Ref: https://medium.com/nosort/adding-views-on-top-of-unityplayer-in-unityplayeractivity-e76240799c82
Solution:
Step1: Make a custom layout XML file (vuforia_widget_screen.xml). For example, button has been added.
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/main_layout">
<FrameLayout
android:id="#+id/unity_player_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<Button

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:background="#null"
android:text="#string/welcome" />
</FrameLayout>
Step 2: Make following changes in the UnityPlayerActivity.java
Replace "setContentView(mUnityPlayer);" with
setContentView(R.layout.vuforia_widget_screen);
FrameLayout frameLayout = findViewById(R.id.unity_player_layout);
frameLayout.addView(mUnityPlayer.getView());
-> For anyone, who will face the issue in future. :)
I'm using a TranslateAnimation to make a fragment (GoogleMap) sliding down to give space to an EditText and a TextView to be visible.
so I used this:
text: TextView
edit: EditText
MapLayout: a LinearLayout that contains the Map
Animation animation = new TranslateAnimation(
MapLayout.getX(), MapLayout.getY(),MapLayout.getY(), text.getHeight()+edit.getHeight());
The problem is that I can't make the slide because text.getHeight()+edit.getHeight() returns 0 so there's no slide!
I tried using a number (100 for exemple), the slide is made, but it's different between the devices, I tested on a Galaxy S3 and the slide is not complete, there's still a part of the EditText which is not visible, as for the emulator it worked ok.
When I tried to make the number a bit bigger, so the slide will be longer (200 for exemple), well... the slide was good for the S3, but i was big for the emulator.
So what I want to know is that if there's any way to make the slide move to a point, without depending on the device, I mean without using pixels; so the slide will work perfectly in any device/
I hope that my problem is clear.
Thank you
Update: I don't if this will help, I added a Toast message, show the height of the EditText and the TextView, in the Emulator it says: 85 and in the S3 it says 181
So yeah, I need to make the map slide down in any device like I said
MainActivity:
protected Animation animation;
protected LinearLayout MapLayout;
protected EditText edit;
protected TextView text;
MapLayout = (LinearLayout)findViewById(R.id.MapLayout);
edit = (EditText)findViewById(R.id.Recherche);
text = (TextView)findViewById(R.id.CaptionRecherche);
Toast.makeText(context, "Height: "+(edit.getHeight()+text.getHeight()), 1000).show();
animation = new TranslateAnimation(MapLayout.getX(), MapLayout.getY(), MapLayout.getY(), text.getHeight()+edit.getHeight());
animation.setDuration(1000);
animation.setFillAfter(true);
MapLayout.startAnimation(animation);

As a part of my application, I have a status bar which contains some text. This status bar is hidden until the user clicks a button at which point it slides down (hiding the topmost content of the layout below).
The code I use to get the correct height of the hidden status bar:
private int hiddenStatusHeight;
private int currentStatusBarHeight;
private void getStatusBarHeight() {
final ViewTreeObserver observer = hiddenStatus.getViewTreeObserver();
observer.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#SuppressLint("NewApi") #SuppressWarnings("deprecation") #Override public void onGlobalLayout() {
hiddenStatus.measure(MeasureSpec.UNSPECIFIED,
MeasureSpec.UNSPECIFIED);
hiddenStatusHeight = hiddenStatus.getMeasuredHeight();
currentStatusBarHeight = statusBar.getHeight();
ViewTreeObserver obs = hiddenStatus.getViewTreeObserver();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
obs.removeOnGlobalLayoutListener(this);
} else {
obs.removeGlobalOnLayoutListener(this);
}
}
});
}
The code that is executed when the button is clicked:
private OnClickListener ExpandClickListener = new OnClickListener() {
#Override public void onClick(View v) {
boolean isExpanded = (Boolean) expandButton
.getTag(R.id.TAG_EXPANDED);
int originalHeight = (Integer) expandButton
.getTag(R.id.TAG_ORIGINAL_HEIGHT);
if (isExpanded) {
expandButton.setTag(R.id.TAG_EXPANDED, false);
expandButton.setImageResource(R.drawable.ic_action_down);
// statusBar.setLayoutParams(new FrameLayout.LayoutParams(
// LayoutParams.MATCH_PARENT, originalHeight));
Log.d(TAG, "Collapsing to " + originalHeight);
ValueAnimator va = ValueAnimator.ofInt(currentStatusBarHeight,
originalHeight);
va.setDuration(500);
va.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator animation) {
Integer value = (Integer) animation.getAnimatedValue();
statusBar.getLayoutParams().height = value.intValue();
statusBar.requestLayout();
}
});
va.start();
} else {
expandButton.setTag(R.id.TAG_EXPANDED, true);
expandButton.setImageResource(R.drawable.ic_action_collapse);
currentStatusBarHeight = originalHeight + hiddenStatusHeight;
// statusBar.setLayoutParams(new FrameLayout.LayoutParams(
// LayoutParams.MATCH_PARENT, currentStatusBarHeight + 15));
Log.d(TAG, "Expanding to " + originalHeight + "+"
+ hiddenStatusHeight + "=" + currentStatusBarHeight);
ValueAnimator va = ValueAnimator.ofInt(originalHeight,
currentStatusBarHeight);
va.setDuration(500);
va.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator animation) {
Integer value = (Integer) animation.getAnimatedValue();
statusBar.getLayoutParams().height = value.intValue();
statusBar.requestLayout();
}
});
va.start();
}
}
};

Hope some of this may be helpful to you.
Just to mention it, I have asked a similar question where the visible layout is pushed downwards as the menu expands. So have a look at that if you rather want this behaviour: How to animate a slide in notification view that pushes the content view down
Happy coding
I'm new to android, and I'm writing a program use bluetooth, so I use another thread and handler to update UI. When I has only one TextView, it works, but when I add more textview, it doesn't work.
My OnCreate
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tvSpeed = (TextView) findViewById(R.id.SpeedView02);
tvHeart = (TextView) findViewById(R.id.HeartRate02);
tvGrade = (TextView) findViewById(R.id.Grandient02);
btnConnect = (Button) findViewById(R.id.BtnConnect);
btAdapter = BluetoothAdapter.getDefaultAdapter();
if (btAdapter == null) {
Toast.makeText(this,
"Bluetooth is not supported on this hardware platform",
1000).show();
onDestroy();
}
}
My Handler
private final Handler handler = new Handler() {
private int current;
public void handleMessage(Message msg) {
current = (Integer) msg.obj;
switch(msg.what)
{
case 1:
tvSpeed.setText(current + "Km/h");
break;
case 2:
tvHeart.setText(current + "Bps");
break;
default:
break;
}
tvGrade.setText(0); // if I remove this, it works.
}
};

setText(0);
You do realize setText(int) is a function that expects a valid R.string.XXX value...
Clearly, 0 will never be a valid value, it's prolly throwing a "Resource Not found" exception.
Instead of handler, i would suggest you to use AsyncTask which is known as Painless Threading in android.
Inside doInBackground(), implement all your background task
once you are having values, you can make UI updation inside the onPostExecute() method.
