自定義按鈕的實(shí)現(xiàn)，很多自定義的控件都可以以類(lèi)似的方式實(shí)現(xiàn)。比較簡(jiǎn)單

 public class SampleDialog extends Dialog {
    @BindView(R.id.content)
    TextView contextTxt;
    @BindView(R.id.title)
    TextView titleTxt;
    @BindView(R.id.submit)
    TextView submitTxt;
    @BindView(R.id.cancel)
    TextView cancelTxt;

    private Context mContext;
    private String content;//提示內(nèi)容
    private OnCloseListener listener;//按鈕監(jiān)聽(tīng)
    private String positiveName;//確認(rèn)文本
    private String negativeName;//取消文本
    private String title;//標(biāo)題

    //Dialog本身的構(gòu)造函數(shù)就不添加了，實(shí)現(xiàn)的時(shí)候需補(bǔ)上驮宴，這里放上需要的構(gòu)造函數(shù)
    public SampleDialog(Context context, int themeResId, String content, OnCloseListener listener) {
        super(context, themeResId);
        this.mContext = context;
        this.content = content;
        this.listener = listener;
    }

    //設(shè)置標(biāo)題
    public SampleDialog setTitle(String title){
        this.title = title;
        return this;
    }

   //設(shè)置確認(rèn)文本
    public SampleDialog setPositiveButton(String name){
        this.positiveName = name;
        return this;
    }

 //設(shè)置取消文本
    public SampleDialog setNegativeButton(String name){
        this.negativeName = name;
        return this;
    }

     //設(shè)置確認(rèn)點(diǎn)擊事件
    @OnClick(R.id.submit)
    void clickSubmit(){
        if(listener != null){
            listener.onClick(this, true);
        }
        this.dismiss();
    }

  //設(shè)置確認(rèn)取消點(diǎn)擊事件
    @OnClick(R.id.cancel)
    void clickCancel(){
        if(listener != null){
            listener.onClick(this,false);
        }
        this.dismiss();
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog_commom);//設(shè)置dialog，具體的樣式請(qǐng)隨意發(fā)揮呕缭，只需保證有4個(gè)控件堵泽，標(biāo)題，內(nèi)容文本恢总，確認(rèn)按鈕迎罗，取消按鈕
        setCanceledOnTouchOutside(false);
        ButterKnife.bind(this);
        initView();
    }

    //初始化文本
    private void initView(){
        contextTxt.setText(content);
        if(!TextUtils.isEmpty(positiveName)){
            submitTxt.setText(positiveName);
        }

        if(!TextUtils.isEmpty(negativeName)){
            cancelTxt.setText(negativeName);
        }

        if(!TextUtils.isEmpty(title)){
            titleTxt.setText(title);
        }

    }

  //接口，需在實(shí)際使用中實(shí)現(xiàn)
    public interface OnCloseListener{
        void onClick(Dialog dialog, boolean confirm);
    }
}

實(shí)現(xiàn)的例子

SampleDialog dialog2 = new SampleDialog(xxxActivity.this,R.style.dialog, "hello world", new SampleDialog.OnCloseListener() {
                    @Override
                    public void onClick(Dialog dialog, boolean confirm) {
                        if(confirm){
                            //DO YES
                        }else{
                            //DO NO
                            dialog.dismiss();//關(guān)閉dialog
                        }
                    }
                });
                dialog2.setPositiveButton("是!");
                dialog2.setNegativeButton("我點(diǎn)錯(cuò)啦片仿！");
                dialog2.show();

補(bǔ)充兩個(gè)內(nèi)容纹安，dialog的THEME，以及 animation 效果
