方法如下

    private void showInputDialog(){
        final EditText inputServer = new EditText(PracticebanjiActivity.this);
        AlertDialog.Builder builder = new AlertDialog.Builder(PracticebanjiActivity.this);
        builder.setTitle("填写会议标题").setIcon(R.drawable.ic_dialog_info).setView(inputServer)
                .setNegativeButton("取消", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                });
        builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                String mMeetName = inputServer.getText().toString();
                //do something...
            }
        });
        builder.show();
    }

没有了
