I am making an app with various activities and each activity uses the camera function which is defined in another class. I want that in each activity when the camera button is clicked the camera class is called.
This is my main class:-
package com.example.ishan.complainbox;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import java.lang.String;
public class Crime extends MainActivity implements View.OnClickListener
{
camera cam=new camera();
EditText str,city,pn,det;
Button save,pic;
crimeDBHandler dbHandler;
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_crime);
// Get References of Views
str = (EditText) findViewById(R.id.str);
city = (EditText) findViewById(R.id.city);
pn = (EditText) findViewById(R.id.pin);
det = (EditText) findViewById(R.id.detail);
save = (Button) findViewById(R.id.save);
pic=(Button) findViewById(R.id.uploadpic);
dbHandler = new crimeDBHandler(this, null, null, 1);
}
public void onClick(View view) {
String street = str.getText().toString();
String cty = city.getText().toString();
String pin = pn.getText().toString();
String detail = det.getText().toString();
// check if any of the fields are vaccant
if(str.equals("")||city.equals("")||pn.equals("")||det.equals(""))
{
Toast.makeText(getApplicationContext(), "Field Vacant",
Toast.LENGTH_LONG).show();
return;
}
// check if both passwords match
else
{
// Save the Data in Database
dbHandler.insertEntry(street,cty,pin,detail);
Toast.makeText(getApplicationContext(), "Complaint Successfully
Filed ", Toast.LENGTH_LONG).show();
}
}
};
.....and this is the camera class..:-
