public class CustomDialogActivity extends Activity {
  
  
    private Button custom = null;
  
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
      
        custom = (Button)this.findViewById(R.id.custom);
        custom.setOnClickListener(new Button.OnClickListener(){
            public void onClick(View v) {
               // TODO Auto-generated method stub
                showCustomDia();
            }
         });
    }
  
  
    private void showCustomDia()
    {
        AlertDialog.Builder customDia=new AlertDialog.Builder(CustomDialogActivity.this);
        final View viewDia=LayoutInflater.from(CustomDialogActivity.this).inflate(R.layout.custom_dialog, null);
        customDia.setTitle("新建文件夹");
        customDia.setView(viewDia);
        customDia.setPositiveButton("确定", new DialogInterface.OnClickListener() {
          
            public void onClick(DialogInterface dialog, int which) {
                // TODO Auto-generated method stub
                EditText diaInput=(EditText) viewDia.findViewById(R.id.file_name);
              
              
            }
        });
        customDia.create().show();
