This "Code A" is the code of my base class and i am extending this class to another class "Code B". The problem is when i run my app my application has stopped. Is there any problem with my Base class or i not call them properly? Activity is registered in manifest file.
Code A
public class PrepaidBase extends Activity {
PrepaidBase pb = new PrepaidBase();
private String number = "";
public void alertDialogShow(Context context, String title, String message, String _number) {
this.number = _number;
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle(title);
builder.setMessage(message);
builder.setCancelable(false);
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
call();
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
dialog.cancel();
}
});
}
public void call()
{
Intent in = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + Uri.encode(number)));
try
{
startActivity(in);
}catch (ActivityNotFoundException e)
{
e.printStackTrace();
}
}
Code B
public class PrepaidLBO extends PrepaidBase {
Button chobeesButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.chobeesghantay);
chobeesButton = (Button)findViewById(R.id.chobeesButton);
pb.alertDialogShow(PrepaidLBO.this, "Some Test" , "Text Here too" , "*1234#");
chobeesButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
call();
}
});
}

You can also implement BASE class like this
public class PrepaidBase extends Activity {
AlertDialog.Builder builder;
private String number = "";
private String packageName;
private String price;
private String title;
public PrepaidBase()
{}
public void setPackageInformation(String name, String price, String number, String title)
{
this.number = number;
this.packageName = name;
this.price = price;
this.title = title;
}
public void activatePackage()
{
try
{
new AlertDialog.Builder(PrepaidBase.this)
.setTitle(PrepaidBase.this.title)
.setMessage("Are you sure you want to activate " + PrepaidBase.this.packageName + " in RS: " + PrepaidBase.this.price)
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Intent in = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + Uri.encode(PrepaidBase.this.number)));
startActivity(in);
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
})
//.setIcon(android.R.drawable.ic_dialog_alert)
.show();
}catch (ActivityNotFoundException e)
{
e.printStackTrace();
}
}
and you other CHILD class which inherit from your BASE
public class PrepaidLBO extends PrepaidBase implements View.OnClickListener {
Button chobeesButton;
public PrepaidLBO()
{
setPackageInformation("Package Name", "Your Price", "*123#", "Your Title");
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.chobeesghantay);
chobeesButton = (Button) findViewById(R.id.chobeesButton);
chobeesButton.setOnClickListener(this);
}
@Override
public void onClick(View v)
{
activatePackage();
}
回答2:
You are recursivly creating a lot of instances.
Your problem is this line PrepaidBase pb = new PrepaidBase(); , which is inside PrepaidBase activity.
Meaning every time an instance of PrepaidBase is created, it creates another instance of itself, until you reach the memory limit, and GC kicks in.
