i expected that when i write admin admin for username and password, it saved it and for the second time i open the app it skip that login page but its not work and show the login page again

You are not initialising the sharedPreference before using it and defining two sharedPreferences for each key-pair. Change your code as below.
public class Login_page extends AppCompatActivity {
TextView tv_user, tv_pass;
EditText tx_user, tx_pass;
Button btn_login;
ImageView img_ghorme;
SharedPreferences save;
public void findall()
{
tv_user = findViewById(R.id.tv_user);
tv_pass = findViewById(R.id.tv_pass);
tx_user = findViewById(R.id.tx_user);
tx_pass = findViewById(R.id.tx_pass);
btn_login = findViewById(R.id.btn_login);
img_ghorme = findViewById(R.id.img_ghorme);
}
public String save_user = "";
public String save_pass = "";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
findall();
save = getSharedPreferences("userInfo", MODE_PRIVATE);
save_user = save.getString("username", "");
save_pass = save.getString("password", "");
if(save_user.equals("admin") && save_pass.equals("admin"))
{
Intent skip = new Intent(Login_page.this, food_page.class);
startActivity(skip);
}
btn_login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
String user = tx_user.getText().toString();
String pass = tx_pass.getText().toString();
SharedPreferences.Editor e = save.edit();
e.putString("username", user);
e.putString("password", pass);
e.apply();
if(user.equals("admin") && pass.equals("admin"))
{
Intent food = new Intent(Login_page.this, food_page.class);
startActivity(food);
}
if (!user.equals("admin") || !pass.equals("admin"))
{
e.putString("username", "");
e.putString("password", "");
e.apply();
tx_user.setText("");
tx_pass.setText("");
}
}

How do i exit runnable and switch another activity

I have a textview timer, i want it stops after 10 seconds of showing on display and after 10 seconds that my current activity jumps to an other activity
Runnable runnable = new Runnable()
{
#Override
public void run()
{
while(Running)
{
try{
Thread.sleep(1000);
}catch(InterruptedException e)
{
e.printStackTrace();
}
handler.post(new Runnable()
{
#Override
public void run()
{
number+=1;
tvTimer.setText(String.valueOf(number)); //With setting value of number on textfield ITS POSSIBLE TO SEE THE TIMER
if(number==10)
{
Running = false;
handler.removeCallbacks(this);//that does not works for me to stop
Intent i = new Intent(getApplicationContext(), SonucMenu.class);
startActivity(i); //Starting my second class
}
}
});
}
}
My Second activity starts but the layout from second activity comes more than one time, what i want is that it comes only one time, and i think this problem depends on that i cant stop runnable

I think for this you can use following code , It worked for me.
It will start your activity after 10 seconds.
new Handler().postDelay(new Runnable() {
#Override
public void run() {
Start Your activity here.
}
}, 10000);
but one of the best solution will be (I just found it from develoer site):
new CountDownTimer(10000, 1000) {
public void onTick(long millisUntilFinished) {
mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
}
public void onFinish() {
strat your activity here.
}
}.start();

Use View.post(Runnable) and View.postDelayed(Runnable, long), no need to create additional thread.
private TextView tvTimer;
private final Runnable mCountDownRunnable = new Runnable() {
private int mCount = 0;
#Override
public void run() {
mCount++;
if (mCount < 10) {
tvTimer.setText(Integer.toString(mCount));
tvTimer.postDelayed(this, 1000);
} else {
Intent i = new Intent(YourActivity.this, SonucMenu.class);
YourActivity.this.startActivity(i);
}
}
};
to start runnable, call tvTimer.post(mCountDownRunnable);

My problem is that when I run the program, it crashes immediately. I'm not sure what's going wrong. I am currently trying to adapt another multiple checkbox program to work for my needs: 'http://pulse7.net/android/android-check-box-example/'.
Essentially I have four grades of foam, and multiple thicknesses, so each grade, if checked in the checkbox, will need to lead to a different method. Currently, the Toast.makeText parts are just a placeholder for what will go there eventually once this part gets figured out :)
Cheers!

You must findViewById() in onCreate() method after setContentView() call.
public class MainActivity extends Activity {
CheckBox chkMD;
CheckBox chkHD;
CheckBox chkYE;
CheckBox chkOE;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_price_estimator);
chkMD = (CheckBox) findViewById(R.id.checkBox1);
chkHD = (CheckBox) findViewById(R.id.checkBox2);
chkYE = (CheckBox) findViewById(R.id.checkBox3);
chkOE = (CheckBox) findViewById(R.id.checkBox4);
// Attach listeners to the checkboxes
chkMD.setOnCheckedChangeListener(this);
chkHD.setOnCheckedChangeListener(this);
chkYE.setOnCheckedChangeListener(this);
chkOE.setOnCheckedChangeListener(this);
}
}

How would i make a button to switch where points go in a counter?

I am currently a high school student who decided to try and take up Android dev for fun, but I am stumped. I have an image button for blue team and for red team. The score goes up automatically for blue team. What i dont know how to do is when you hit the red button, the image buttons make the red teams score go up and vice versa.
Here is my java code
package com.example.puremmacompetitionjiujitsuscorer;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.ImageButton;
import android.widget.TextView;
import android.widget.Toast;
class MainActivity extends Activity {
private int blueScore = 0;
private int redScore = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ImageButton sweep = (ImageButton) findViewById(R.id.imageButton5);
final ImageButton pass = (ImageButton) findViewById(R.id.imageButton8);
final ImageButton mount = (ImageButton) findViewById(R.id.imageButton4);
final ImageButton backMount = (ImageButton) findViewById(R.id.imageButton3);
final ImageButton kneeOnBelly = (ImageButton) findViewById(R.id.imageButton7);
final ImageButton takeDown = (ImageButton) findViewById(R.id.imageButton6);
final TextView blueScoreCount = (TextView) findViewById(R.id.blueScore1);
takeDown.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
blueScore += 2;
blueScoreCount.setText("" + blueScore);
}
});
sweep.setOnClickListener(new View.OnClickListener(){
public void onClick(View w) {
blueScore += 2;
blueScoreCount.setText("" + blueScore);
}
});
pass.setOnClickListener(new View.OnClickListener(){
public void onClick(View q){
blueScore += 3;
blueScoreCount.setText("" + blueScore);
}
});
mount.setOnClickListener(new View.OnClickListener(){
public void onClick(View t){
blueScore += 4;
blueScoreCount.setText("" + blueScore);
}
});
backMount.setOnClickListener(new View.OnClickListener(){
public void onClick(View s){
blueScore += 4;
blueScoreCount.setText("" + blueScore);
}
});
kneeOnBelly.setOnClickListener(new View.OnClickListener(){
public void onClick(View g){
blueScore += 2;
blueScoreCount.setText("" + blueScore);
}
});
};

getMenuInflater().inflate(R.menu.main, menu);

I think I possibly understand you. If I do, you can use a flag to see which Button was pressed. So the flow would be like
Red button pressed -> flag = red -> Score Button pressed -> red score += score
In code it would be like
String flag = "";
public void onRedBtnClick(View v)
{
flag = "red";
}
public void scoreBtnClick(View v)
{
if (!flag.equals(""));
{
if ("red".equals(flag))
{
redScore += score;
}
if ("blue".equals(flag))
{
blueScore += score;
}
}
This is obviously done really quick and you will have to adjust your variables to your needs. But if I understand what you want then this would give you the basic logic

Moving TextView Box made my android app crash

I have had this problem crop up a few times and I can't figure out why it should happen. What happened was after moving some stuff around my TextView box ended up on top of an EditText box, which is no good. So I went and moved the TextView box to the bottom of the screen. When I did that, the app would crash when I tried to access the piggybank. However, if I move the TextView box up to the top again, it works fine.. I really don't get it. Anyways, this is the error that I got

Try cleaning your project on Eclipse. It often fixes that kind of problems.
