SeekBar RGB picker keeps stoping

SeekBar RGB picker keeps stoping - java

I am trying to do app, where you have 3 SeekBars and under them, there are 3 TextFields, which are showing shade of each color, and under those is TextField, which is changing color when you are moving SeekBar. When I try to lunch it on mobile, it say's that the app "Keeps stopping". Thanks for help.

sbB.setOnSeekBarChangeListener(msbclB);
}
}

You didn't initialize text views...
TVr = findViewById(R.id.TVr); - do it for all 3 TextViews TVr, TVg, TVb;
Also:
You have to initialize vysledek.
You have to cast progress (seekR, seekG, seekB) to String in onProgressChanged() method - TVr.setText(String.valueOf(seekR));
Your layout is also very poor. You haven't mentioned the orientation android:orientation="horizontal" and the positioning for the LinearLayout as well.

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;
}
}

</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)

Animation Problems in Android

I've got few problems in using animation in android studios:
I'm trying to translate certain images at an angle. Like in the image below I want to move that attachment pin like icons to all the ends of the corner. How can I do this?
I was trying to scale up the image of the gear image in the center every time its tapped and scale down when tapped again. However, the image starts losing its quality. How can I prevent the quality from getting deteriorated?
Here's the code:
MainActivity.java
package com.rootonelabs.vicky.pulse;
import android.animation.AnimatorSet;
import android.animation.ObjectAnimator;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {
PulseView pulseView;
Button btnStart, btnStop;
ImageView gear;
ImageView icon1,icon2,icon3,icon4,icon5,icon6;
int chkClick = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pulseView = (PulseView)findViewById(R.id.pv);
btnStart = (Button)findViewById(R.id.btnStart);
btnStop = (Button)findViewById(R.id.btnStop);
btnStart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
pulseView.startPulse();
}
});
btnStop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
pulseView.finishPulse();
}
});
gear = (ImageView)findViewById(R.id.gear);
gear.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
gear.animate().scaleX(1.5f).scaleY(1.5f).setDuration(500);
animateDiagonalPan();
icon1 = findViewById(R.id.icon1);
icon1.animate().translationXBy(120).translationYBy(120).setDuration(500);
if(chkClick==0)
{
pulseView.animate().alpha(0).setDuration(500);
gear.animate().scaleX(1.5f).scaleY(1.5f).setDuration(500);
pulseView.finishPulse();
chkClick = 1;
}else{
pulseView.animate().alpha(1f).setDuration(500);

Cant see all of my buttons on a phone

**I am making some app and cant see a button that I have created (this is when running the app on my phone) ,but if I run it on the emulator I can see everything - the button that I can't see on my phone is the clicked button (its id is "startBtn").
**
Here is my layout :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:background="#798"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="unleashed.myprefs.MainActivity">
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="90dp"
android:text="hello"
android:background="#ff14"
/>
<Button
android:id="#+id/startBtn"
android:text="start"
android:layout_below="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="addOne"

And this is my main activity
package unleashed.myprefs;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {

SharedPreferences prefs;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
prefs = getSharedPreferences("main", MODE_PRIVATE);
}
private int getNum(){
return prefs.getInt("num",1);
}
private void setNum(int num){ // put the number into my shared preference
prefs.edit().putInt("num", num).apply();
}
public void addOne(View v) { //adding number to the starting button
int num = getNum();
((Button)v).setText("Clicked " + num);
setNum(num + 1);
}
public void restart(View v){
restartNums = (Button) findViewById(R.id.startBtn);
prefs.edit().remove("num").apply();
restartNums.callOnClick();
}
}
I will appreciate any help.

AlignParentEnd should be used in ResetButton.( Not sure )
(Alternative) If you trying to have two buttons in the same row, you can try this layout..
`
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="90dp"
android:text="hello"
android:background="#ff14"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation = "horizontal"
android:weightsum="2"
android:layout_below="#+id/textView">
<Button
android:id="#+id/startBtn"
android:text="start"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:onClick="addOne"
/>
<Button
android:id="#+id/resetBtn"
android:text="restart"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:onClick="restart"/>

How to do enable a button and change its colour when textfield has some value?

I have tried many answers already given to this, but nothing seems to work properly. And the answers are only for changing state of the button, not colour and text. What am I missing?
I am a very VERY new learner to both Android and programming. And this is my first question on Stack Overflow. Hope it's as per guidelines.
I have a login page which looks like below (img1) [disabled][1]. If textfield has any value, the button should get enabled (img2) [enabled][2]. The Java and XML files are given below.
