I have buttons V1-V8 visible and R1-R8 invisible initially in my activity_main.xml file
My MainActivity.java file
package com.example.buttonvtor;
import com.example.buttonvtor.MainActivity;

import android.widget.Toast;
public class MainActivity extends Activity implements OnClickListener{
Button bv1;
Button bv2;
Button bv3;
Button bv4;
Button bv5;
Button bv6;
Button bv7;
Button bv8;
Button br1;
@Override

super.onCreate(savedInstanceState);

}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void onClick(View v) {
switch(v.getId()){
case R.id.button1:
Toast.makeText(MainActivity.this,"You clicked on block 1",Toast.LENGTH_LONG).show();

}
}
protected void onActivityResult (int requestCode, int resultCode, Intent data)
{
if (requestCode == 1)
{// here you match the number you sent in startActivityForResult
if (resultCode == RESULT_OK)
{
bv1.setVisibility(View.INVISIBLE);
br1.setVisibility(0);
}
// do something
}
}
}
Once I click on say button V1 it goes to the next activity called Payment1Activity.java and checks the users validity. If a user is valid and the payment is successful it comes back to my MainActivity.java.
Payment1Activity.java

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_payment1);
b = (Button)findViewById(R.id.Button01);
et = (EditText)findViewById(R.id.accountno);
pass= (EditText)findViewById(R.id.password);
tv = (TextView)findViewById(R.id.tv);
b.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dialog = ProgressDialog.show(Payment1Activity.this, "",
"Validating user...", true);
new Thread(new Runnable() {
public void run() {
payment();
}
}).start();
}
});
}
void payment(){
try{
httpclient=new DefaultHttpClient();
httppost= new HttpPost("my url");
//add your data
nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("accno",et.getText().toString().trim()));
nameValuePairs.add(newBasicNameValuePair("bpassword",pass.getText().toString().trim()));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
//Execute HTTP Post Request
response=httpclient.execute(httppost);
ResponseHandler<String> responseHandler = new BasicResponseHandler();
final String response = httpclient.execute(httppost, responseHandler);
System.out.println("Response : " + response);
runOnUiThread(new Runnable() {
public void run() {
tv.setText("Response from PHP : " + response);
dialog.dismiss();
}
});
if(response.startsWith("User Found")){
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(Payment1Activity.this,"Payment Successful", Toast.LENGTH_SHORT).show();
Toast.makeText(Payment1Activity.this,"You reserved block 1",Toast.LENGTH_LONG).show();
}
});
Intent returnIntent = new Intent();
returnIntent.putExtra("Payment Successful",RESULT_OK);
setResult(RESULT_OK,returnIntent);
finish();
startActivity(new Intent(Payment1Activity.this, MainActivity.class));
}else{
showAlert();
}
}catch(Exception e){
dialog.dismiss();
System.out.println("Exception : " + e.getMessage());
}
}
public void showAlert(){
Payment1Activity.this.runOnUiThread(new Runnable() {
public void run() {
AlertDialog.Builder builder = new AlertDialog.Builder(Payment1Activity.this);
builder.setTitle("Payment Error.");
builder.setMessage("User not Found.")
.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
AlertDialog alert = builder.create();
alert.show();
}
});
}
}
So I want something such that when my Payment1Activity.java says payment successful and redirects a user to main page at that time my V1 Button should get invisible and R1 should get visible. I tried different permutations and combinations to achieve this but it did not help. Please help. Any suggestions or advices will be highly appreciated. Thank you.
