GestureDetector not working on new layout

GestureDetector not working on new layout - java

I have created the standard gesture detector that changes a textview depending on the given gesture. All works fine when my XML contains only the relative layout and the text view I wish to change. However when I add a gird layout and a few icons the Gesture Detector no longer works, simply not changing the textview as it did before.
The code is;
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

And the Java
import android.app.Activity;

public class MainActivity extends Activity implements

private GestureDetectorCompat gestureDetector;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
someText = (TextView)findViewById(R.id.someText);
this.gestureDetector = new GestureDetectorCompat(this, this);
gestureDetector.setOnDoubleTapListener(this);
}
#Override
public boolean onSingleTapConfirmed(MotionEvent e) {
someText.setText("SINGLETAP");
return true;
}
#Override
public boolean onDoubleTap(MotionEvent e) {
someText.setText("DOUBLETAP");
return true;
}
#Override
public boolean onDoubleTapEvent(MotionEvent e) {
someText.setText("DOUBLETAPEVENT");
return true;
}
#Override
public boolean onDown(MotionEvent e) {
someText.setText("DOWN");
return true;
}
#Override
public void onShowPress(MotionEvent e) {
someText.setText("PRESS");
}
#Override
public boolean onSingleTapUp(MotionEvent e) {
someText.setText("SINGLETAPUP");
return true;
}
#Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
someText.setText("SCROLL");
return true;
}
#Override
public void onLongPress(MotionEvent e) {
someText.setText("LONGPRESS");
}
#Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
someText.setText("FLING");
return true;
}
#Override
public boolean onTouchEvent(MotionEvent event) {
gestureDetector.onTouchEvent(event);
return false;
}
}
Note if I comment out the grid layout and the image views then the code works again changing the textview. I can only presume the gesture detector is now buried beneath the grid layout but aren't sure?

Try to remove this lines in your layout, they are useless in your case
android:clickable="true"
android:focusable="true"
android:focusableInTouchMode="true"

Cannot see widgets in tab layout in android studio

I am facing the problem of cannot see widgets in tab layouts. I have created textview and button in Overview Fragment but I cannot see them when run code. Is it right to initialize textviews and buttons in oncreateview() of fragment which we don't want to transfer to another tab. I have searched a lot about my problem but cannot get any hint. Code is given below:

How to slide the main layout and force it to resize?

I want to create an text editor with options at the top (bold,..).
I also want to be able to hide those options; using the exact transition style shown in the picture below.
My problem is that the EditText that I use never has the intended behavious. (In the GIF below for exemple it does not resize after being moved).
I tried using animate (which is what is shown here on the picture).
I also tried with layout animation, combined with setVisibility(View.GONE) when the animation ends (its nearly perfect but for one frame between the two we can see what's happening).
I finally tried setting android:animateLayoutChanges="true". Which works great but I cannot animate the transition as I want.
I also tried combining the three in various ways, but never was successful.
Java:
public class MainActivity extends AppCompatActivity {
boolean optionVisible = true;
LinearLayout Main;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Main = findViewById(R.id.main);
}
public void show(View v) {
if (optionVisible) {
Main.animate().setDuration(300).translationYBy(-Options.getHeight());
} else {
Main.animate().setDuration(300).translationYBy(Options.getHeight());
}
optionVisible = !optionVisible;
}
}
XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/main"

android:layout_height="wrap_content"
android:orientation="vertical"
android:fillAfter="true">

</LinearLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp">

<EditText
android:id="#+id/writter"
android:layout_width="match_parent"

android:text="azertyuio"
android:textAlignment="gravity"
android:textColor="#color/text"
android:textSize="20sp"
tools:ignore="HardcodedText"
android:background="#null"
/>
</LinearLayout>

Well I finally managed to get it working properly. I still find the solution akward and would be glad to here another suggestion.
Anyway what I finally did was to use Animations (and not animate), and to have 2 main view basically being set GONE and VISIBLE at oppisite time depending on the presence of options or not.
Here is the code (I used an external class to synchronize the two EditText)

Above is my full code of fragment.I need to swipe without selecting the layer.how can I code.this image show the selection of particular layer,I am not able to swipe over this layer without selection.

Why is my text aligned to the left?

I'm new to Android developing, and I just couldn't fix this problem. When I build this app, my initial text is centered, but when I click the button or long click it, the response text is left aligned. And also, double tap, scrolling and flinging gestures don't work at all. What can be the reason?

this.gestureDetect = new GestureDetectorCompat(this, this);
gestureDetect.setOnDoubleTapListener(this);
button1.setOnClickListener(
new View.OnClickListener() {
#Override

txt1.setText("clicked to the button whooaoaaa");
}
}

For first problem (wrong text aligned)
You should set your TextView width as match_parent and gravity to center_horizontal. So your code should be something like this:
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="160dp"
android:text="#string/initial_text"
android:textSize="30sp"
android:layout_gravity="center_horizontal"
app:layout_constraintBottom_toTopOf="#+id/button1"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:layout_marginTop="100dp"
android:layout_marginLeft="50dp"
android:layout_marginRight="50dp" />

listView won't populate from bottom
