Why custom dialog box button is not working in android

问题

We have creating two custom dialog box, one is about and another one is alert. When i choose alternately in the tow custom dialog box at that time the button is not working.

Sample code

AlertDialog.Builder builder;
Context mContext;
LayoutInflater inflater;
View layout;
Dialog dialog;
@Override
protected Dialog onCreateDialog( int id ) 
{ 
    switch ( id ) 
    {
        case 1:
            builder = null;
            mContext = this;
            inflater = ( LayoutInflater ) mContext.getSystemService( LAYOUT_INFLATER_SERVICE );
            layout = inflater.inflate( R.layout.alert_page, ( ViewGroup ) findViewById( R.id.alert_Root ) );
            Button alertUser = ( Button ) layout.findViewById( R.id.alert_Submit );
            alertUser.setOnClickListener( new View.OnClickListener()
            {
                public void onClick( View v )
                {
                    try
                    {
                        dialog.dismiss();
                    }
                    catch ( Exception e ) 
                    {
                        Toast.makeText( getBaseContext(), e.getMessage(), Toast.LENGTH_SHORT ).show();
                    }
                }
            });
            builder = new AlertDialog.Builder( mContext );
            builder.setView( layout );
            dialog = builder.create();
            dialog.show();
            break;

        case 2:
            builder = null;
            mContext = this;
            inflater = ( LayoutInflater ) mContext.getSystemService( LAYOUT_INFLATER_SERVICE );
            layout = inflater.inflate( R.layout.about_page, ( ViewGroup ) findViewById( R.id.about_Root ) );
            Button aboutUser = ( Button ) layout.findViewById( R.id.about_Submit );
            aboutUser.setOnClickListener( new View.OnClickListener()
            {
                public void onClick( View v )
                {
                    Log.e("About","About");
                    try
                    {
                        Log.e("About1","About");
                        dialog.dismiss();
                    }
                    catch ( Exception e ) 
                    {
                        Log.e("About","About12");
                        Toast.makeText( getBaseContext(), e.getMessage(), Toast.LENGTH_SHORT ).show();
                    }
                }
            });
            builder = new AlertDialog.Builder( mContext );
            builder.setView( layout );
            dialog = builder.create();
            dialog.show();
            break;
    }
    return dialog;
}

For example i am using two button. First button is called case 1 and second button is called case 2.

I am selected First button to access case 1 and then selected custom dialog box alertUser button successfully Exit the dialog box.

Immediately I am selected Second button to access case 2 and then select custom dialog box aboutUser button successfully Exit the dialog box.

After Immediately I am selected First button to access case 1 and then select custom dialog box alertUser button Now the dialog box does not exist (button is now not working).

Where i am mistaken code. How do solved this problem.

Thanks in advance.

回答1:

you are calling dialog as showDialog(int). remove this line dialog.show(); in your onCreateDialog

and call dismissDialog(int) to dismiss the dialog instead of dialog.dismiss();

回答2:

Do like this:

Button button1=(Button) findViewById(R.id.btn1);
Button button2=(Button) findViewById(R.id.btn2);

 button1.setOnClickListener(this);
 button2.setOnClickListener(this);

implement your Activity by OnClickListener and add unimplemented method which u will get as onClick.

public void onClick(View v) {
switch(v.getId()){
        case R.id.btn1:
            //write code
            break;
        case R.id.btn2:
            //write code
            break;
        }
}

Do whatever you want to do on click event of button.
