Android - TextView is not updated. What goes wrong?

Android - TextView is not updated. What goes wrong? - android

I am trying to make a pedometer.
So as can be seen, once the acceleration of one particular direction exceeds 1, the counter increments by 1. Then I wanna display the count number in the textView.
However, the textView is always displayed as "TextView" instead of the desired number.
Any idea? Thanks!

In Here :
textView.setText(stepCounts); //<<<
you are passing Integer Value to TextView.setText method that's why you are getting Resources$NotFoundException . show Integer value in TextView as:
textView.setText(String.valueOf(stepCounts));

Or simpler just use ""+number in setText() method.

Delay in android step counter

I am developing an android step counter that starts counting when i press a button and stops when i press the button again. The problem is that the counter always misses the first few steps i am using the step counter sensor introduced in android kitkat 4.4. I also tried the step detector sensor but had the same results.
I tried changing the delay when registering the sensor to fastest, game, normal, and I even tried to set the delay to 0 but nothing worked
Is there a way i can fix this?
this is a simple app that shows my problem

Edited: Added code snippets

I realized that using the predefined stepCounter sensor for small number of steps, like what i wanted, isn't the best option and implementing a counter using accelerometer would be a lot better; however it won't be recommended for building fitness apps or any app that require constant step counting for a long time because the delay in the stepcounting sensor is to neglect the false positives.
so this is my implementation of the stepcounter using accelerometer

Button onClick, Cycle through Colors/Backgrounds

I am using Android Studio
I'm wanting to change the color of my button, with each click.
To cycle it through around 10 colors and start over again in a continuous loop.
For example I'm using setBackgroundResource(#drawable/oval)
oval = blue circle button
oval2 = red circle button
oval3 = green circle button and so on.
So far I have it that button1 starts as oval(blue) and onClick turns into oval2(red)
So my question is, how to add another click to change it to oval3(green) and then cycle it back to the start oval(blue)?

You can do this by following:
Create integer-array in resources:
<integer-array name="backgrounds">
<item>#drawable/oval1</item>
<item>#drawable/oval2</item>
<item>#drawable/oval3</item>
<item>#drawable/oval4</item>
<item>#drawable/oval5</item>
</integer-array>
Then create special OnClickListener class inside your class code
private static class MyClickListener implements View.OnClickListener {
private int mBackgroundIndex = 0;
private final TypedArray mBackgrounds;
public MyClickListener(Context context) {
mBackgrounds = context.getResources().obtainTypedArray(R.array.backgrounds);
}
#Override
public void onClick(View v) {
mBackgroundIndex++;
if (mBackgroundIndex >= mBackgrounds.length()) {
mBackgroundIndex = 0;
}
v.setBackgroundResource(mBackgrounds.getResourceId(mBackgroundIndex, 0));
}
#Override
protected void finalize() throws Throwable {
mBackgrounds.recycle();
super.finalize();
}
}
And then set that listener to each button:
button1.setOnClickListener(new MyClickListener(this));
button2.setOnClickListener(new MyClickListener(this));
button3.setOnClickListener(new MyClickListener(this));
button4.setOnClickListener(new MyClickListener(this));
button5.setOnClickListener(new MyClickListener(this));
This should result in the following MainActivity code:

how to get the timer counted value in Android?

How to create an android mobile application that will do a counting in miliseconds (start from 0), and ask user to type"I Like to eat" in EditText and click submit. After user click submit, counting will stop and a dialog box will appear and show the counting result.

How to save history of last user?

User in my app may choose some dates in activity B and the last five choises should be saving.
The problem is that each user can have a different story calculations! In fact my app calculations of last user is remembering but even for new users who should have empty fields for dates.
Its my first activity:

setContentView(R.layout.activity_ekran1);
preferences = getSharedPreferences("Dni Tygodnia", Activity.MODE_PRIVATE);
editText = (EditText) findViewById(R.id.editTextUserName);
String LastUser = preferences.getString("LastUser", "");
editText.setText(LastUser);
//set listeners
editText.addTextChangedListener(textWatcher);
//run once to disable if empty
checkFieldsForEmptyValues();
}
protected TextWatcher textWatcher = new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i2, int i3)

}

}

}
};

How to keep state of RadioButton in Android?

Hi I'm trying to develop an application which runs for every interval time, lets say for every 1 minute it will display some Toast message.
But problem is I'm using RadioButton functionality is perfect but when I tap on one radio button it will be green, but when I close and re-open the activity I'll get as none of the radio buttons selected.
Here is my MainActivity.java
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onRadioButtonClicked(View view) {
// Is the button now checked?
boolean checked = ((RadioButton) view).isChecked();
// Check which radio button was clicked
switch(view.getId()) {
case R.id.radio_one_min:
if (checked)
{
//some code
}
break;
case R.id.radio_ten_min:
if (checked)
{
//some code
}
break;
case R.id.radio_disable:
if (checked)
{
//some code
}
break;
}
}
}
and here is my activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RadioGroup xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="#+id/radio">
<RadioButton android:id="#+id/radio_disable"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Disable"
android:onClick="onRadioButtonClicked"/>
<RadioButton android:id="#+id/radio_one_min"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="1 minute"
android:onClick="onRadioButtonClicked"/>
<RadioButton android:id="#+id/radio_ten_min"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="10 minute"
android:onClick="onRadioButtonClicked"/>
</RadioGroup>
Please help me to solve this riddle.
Thanks in advance...

This code is useful for store the ratingbar state, when we start new activity, you will see the previous rating state..

it is the simplest way to do so,no need of sharedpreference at all.you will get confused while using it.keep the things simple like this
public class MainActivity extends Activity {
Public static int flag=0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(flag==1)
radio_one_min.setChecked(true);
else if(flag==2)
radio_ten_min.setCheckek(true);
else if(flag==3)
radio_disable.setCheckek(true);
}
public void onRadioButtonClicked(View view) {
// Is the button now checked?
boolean checked = ((RadioButton) view).isChecked();
// Check which radio button was clicked
switch(view.getId()) {
case R.id.radio_one_min:
if (checked)
{
flag =1;
//some code
}
break;
case R.id.radio_ten_min:
if (checked)
{
flag=2 ;
//some code
}
break;
case R.id.radio_disable:
if (checked)
{
flag=3;
//some code
}
break;
}
}
}

[EDITED]
I found developer.android.com/training/basics/activity-lifecycle/recreating.html document first, so my first guess was using Bundles and on Save/Resume Instace State methods. However this does not seem to work well. Here's my final attempt at a working solution (using SharedPreferences class, as suggested by some users):
import android.app.Activity;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.os.Bundle;
import android.view.View;
import android.widget.RadioButton;
public class MainActivity extends Activity {
final String PREFERENCES = "prefs";
final String RADIO_BUTTON = "prefsval";
SharedPreferences sp;
Editor e;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sp = this.getSharedPreferences(PREFERENCES, MODE_PRIVATE);
e = sp.edit();
}
#Override
protected void onResume() {
super.onResume();
if (sp != null) {
if (sp.getInt(RADIO_BUTTON, 0) != 0) {
RadioButton rb;
rb = (RadioButton) findViewById(sp.getInt(RADIO_BUTTON, 0));
rb.setChecked(true);
}
}
}
public void onRadioButtonClicked(View view) {
e.putInt(RADIO_BUTTON, view.getId());
e.apply();
}
}

Develop Reference

The Android operating system is a mobile operating system that was developed by Google (GOOGL?) to be primarily used for touchscreen devices, cell phones, and tablets.

Android - TextView is not updated. What goes wrong? - android

In Here : textView.setText(stepCounts); //<<< you are passing Integer Value to TextView.setText method that's why you are getting Resources$NotFoundException . show Integer value in TextView as: textView.setText(String.valueOf(stepCounts));

Or simpler just use ""+number in setText() method.
