How to move ImageView?

How to move ImageView? - android

There are four ImageVIews with colors above and four below.
And there are buttons connected to each color.
If you press the button, the visibility of the image of the same color is gone.
If orange is gone, and pink, skyblue, and emerald is gone, I would like to have purple next to blue.
Should I use another layout or is there any other way?
I don't know what to do.
It's activity_main.xml

You should use GridView or RecyclerView instead. An other way when you want hide an ImageView you set gone the last ImageView and change color of others

Textviews are not showing on real device

When app works fine
When app not shows textviews(its finding a sensor. When cant find, giving info on textview like 'didnt found')
I created a pedometer app. It was working well on my emulator and my own android device. But when ı publish that app my friends said textviews are invisible. I examined that problem in code but didnt found a problem. Textviews are getting their text from sensor. Writing steps and calories, after some calculating. Why that problem showed up? What is the source of this problem? Why is this happening?

I think it's not one of programmatic issue and could be your listview went up to bottom on screen. You could research How to develop an android application for different device sizes. Visit here https://developer.android.com/training/multiscreen/screensizes

I found what is the problem. I was forgetting the add user permissions.
I Added to the Manifest.xml:
<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION"/>
onCreate Method:
if(ContextCompat.checkSelfPermission(this,
Manifest.permission.ACTIVITY_RECOGNITION) == PackageManager.PERMISSION_DENIED){
//ask for permission
requestPermissions(new String[]{Manifest.permission.ACTIVITY_RECOGNITION}, PHYISCAL_ACTIVITY);
}

ViewFlipper outAnimation is not working

I want to continuously show different text on text view which animates from left to right, waits on the center of the screen for 3 sec and animates outside of the screen and replaced by a new text which animates from left to right
I have included a textview inside a viewflipper.

</android.support.constraint.ConstraintLayout>
MainActivity Code
public class Main6Activity extends AppCompatActivity {
private ViewFlipper mViewFlipper;
private int count = 0;
private TextView textView;
private ConstraintLayout rootContainer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main6);
mViewFlipper = findViewById(R.id.view_flipper);
textView = findViewById(R.id.tv);
rootContainer = findViewById(R.id.rl__inc_pre_sing__tm_container);
mViewFlipper.setAutoStart(true);
mViewFlipper.startFlipping();
mViewFlipper.setInAnimation(AnimationUtils.loadAnimation(rootContainer.getContext(), android.R.anim.slide_in_left));
mViewFlipper.setOutAnimation(AnimationUtils.loadAnimation(rootContainer.getContext(), android.R.anim.slide_out_right));
Resources resources = getApplicationContext().getResources();
final String[] textString = resources.getStringArray(R.array.teacher_messages);
new Thread() {
#Override
public void run() {
super.run();
try {
while (!isInterrupted()) {
Thread.sleep(3000);
runOnUiThread(() -> updateText(textString));
}
} catch (Exception e) {
e.printStackTrace();
}
}
}.start();
}
public void updateText(String[] strings) {
if (count >= strings.length) {
count = 0;
}
textView.setText(strings[count]);
count++;
}
}
I guess the outanimation does not work as the textview length changes and I want to animate the constraint layout according to the textview height.
Not sure if this is the right reason.
The outAnimation of the view flipper does not work.

That's not how ViewFlipper works . the View flipper will only animate the view added to it .
Here's an example :
<ViewFlipper
android:id="#+id/viewFlipper"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/loading"
android:autoStart="true"
android:flipInterval="5000"
android:inAnimation="#android:anim/slide_in_left"
android:outAnimation="#android:anim/slide_out_right">
<TextView
fontPath="fonts/benton_light.ttf"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="#string/text1"
android:textColor="#color/white"
android:textSize="18sp" />
<TextView
fontPath="fonts/benton_light.ttf"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="#string/text3"
android:textColor="#color/white"
android:textSize="18sp" />
<TextView
fontPath="fonts/benton_light.ttf"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="#string/tex2"
android:textColor="#color/white"
android:textSize="18sp" />
</ViewFlipper>

How to create a 3*3 Matrix Grid in android

I want to make a simple Sudoku game in which i want to create 3*3 matrix.I created a matrix but i getting problem how to insert some value at specific position in Grid Layout.Please can anyone help me.
I have done up to this so far...
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mScrollView = (ScrollView) findViewById(R.id.scroll_view);
mScrollView.setSmoothScrollingEnabled(true);
mGrid = (GridLayout) findViewById(R.id.grid_layout);
// mGrid.setOnDragListener(new DragListener());
final LayoutInflater inflater = LayoutInflater.from(this);
for (int i = 0; i < NBR_ITEMS; i++) {
final View itemView = inflater.inflate(R.layout.item_grid, mGrid, false);
final TextView text = (TextView) itemView.findViewById(R.id.text);
if ((i == 4)) {
text.setText("3");
}
if ((i == 2)) {
text.setText("2");
}
if ((i == 7)) {
text.setText("1");
}
final int size = mGrid.getChildCount();
System.out.println("size===" + size);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
final int index = calculateNewIndex(itemView.getX(), itemView.getY());
System.out.println("index====" + index);
System.out.println("click on cell");
}
});
// itemView.setOnLongClickListener(new LongPressListener());
mGrid.addView(itemView);
}
}

Simply you can create 3*3 matrix using LinearLayout and do wahtever you want like this,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"

/>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight=".33"
android:text="2"

After apply above code
I am getting like this image
this image

We can do it easily as per attached image
Made visible when need of Highlighter under text views or adjacent of image.
or Made invisible when not need or pressed That's it .
Wrote code for same which is working .
text color change on the basis of text selection :
text_color.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#00b200"></item>
<item android:state_focused="true" android:color="#00b200"/>
<item android:state_selected="true" android:color="#000000"/>
<item android:color="#d3d3d3"></item>
</selector>
