  • 0

So basically I’m using a TabGroupActivity inside my TabHost,so I can switch different activities inside of one tab.Two days before the code that I’m running right now was ok,without any exceptions.But in that time I was flipping views inside the tab.Now I change all views with different activities.So my situation is something like that:

Main tab Activity -> opens Second activity -> which opens the third activity ,where the AlertDialog is.

The code I’m using is that :

Button deactivate = (Button) findViewById(R.id.deactivate);
        deactivate.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                new AlertDialog.Builder( getParent() )
                .setTitle( "Warning" )
                .setMessage( "The collection will be removed completely from the device.You can reactivate it later again.This operation requires internet connection." )
                .setPositiveButton( "Go ahead", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        Log.d("AlertDialog", "Positive");
                    }
                })
                .setNegativeButton( "Cancel", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        Log.d("AlertDialog","Negative");
                    }
                })
                .show();    

            }

    });

and the Exception is :

08-14 11:08:33.254: ERROR/AndroidRuntime(4726): FATAL EXCEPTION: main

    Button deactivate = (Button) findViewById(R.id.deactivate);
        deactivate.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                new AlertDialog.Builder( yourActivity.this )
                .setTitle( "Warning" )
                .setMessage( "The collection will be removed completely from the device.You can reactivate it later again.This operation requires internet connection." )
                .setPositiveButton( "Go ahead", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        Log.d("AlertDialog", "Positive");
                    }
                })
                .setNegativeButton( "Cancel", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        Log.d("AlertDialog","Negative");
                    }
                })
                .show();    

            }

    });

    try it out, pass your running activity’s context
