<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:minHeight="25px"

        android:typeface="sans" />
</LinearLayout>

设定班级

public class SettingDialog extends Dialog implements View.OnClickListener
{
    private Activity c;
    private Button btnSave;
    private TextView txtTitle;
    private int layoutResID;
    private OnSettingDialogClickListener mSaveClickListener;
    public static interface OnSettingDialogClickListener {
        public void onClick(SettingDialog settingDialog);
    }
    public SettingDialog(Activity a, int layoutResID) {
        super(a);
        // TODO Auto-generated constructor stub
        this.c = a;
        this.layoutResID = layoutResID;
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(layoutResID);
        btnSave = (Button) findViewById(R.id.btnSave);
        txtTitle  = (TextView) findViewById(R.id.setting_title);
        this.setCancelable(true);
        this.setCanceledOnTouchOutside(false);
    }
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
    public void setCancelable(Boolean cancelable)
    {
        this.setCancelable(cancelable);
    }
    public void setTitle(String title) {
        this.txtTitle.setText(title);
    }
    public SettingDialog setSaveClickListener(String textName, OnSettingDialogClickListener listener) {
        mSaveClickListener = listener;
        btnSave.setText(textName);
        return this;
    }
    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btnSave:
                if (mSaveClickListener != null) {
                    mSaveClickListener.onClick(SettingDialog.this);
                }
                break;
            default:
                break;
        }
    }
}

呼叫设置自定义对话框

private void ShowSetting() {
        SettingDialog settingDialog = new SettingDialog(PlayActivity.this, R.layout.setting_dialog);
        settingDialog.setTitle("Setting");
        settingDialog.setSaveClickListener("Save", new SettingDialog.OnSettingDialogClickListener() {
            @Override
            public void onClick(SettingDialog sDialog) {
                LogHelper.d("PlayActivity", " Save button ");
                sDialog.dismiss();
            }
        });
        settingDialog.show();
    }

设置自定义对话框apear，然后触摸保存按钮，但它没有任何功能。

你能帮我吗？
