自定义按钮的实现,很多自定义的控件都可以以类似的方式实现。比较简单
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;//提示内容
private OnCloseListener listener;//按钮监听
private String positiveName;//确认文本
private String negativeName;//取消文本
private String title;//标题
//Dialog本身的构造函数就不添加了,实现的时候需补上,这里放上需要的构造函数
public SampleDialog(Context context, int themeResId, String content, OnCloseListener listener) {
super(context, themeResId);
this.mContext = context;
this.content = content;
this.listener = listener;
}
//设置标题
public SampleDialog setTitle(String title){
this.title = title;
return this;
}
//设置确认文本
public SampleDialog setPositiveButton(String name){
this.positiveName = name;
return this;
}
//设置取消文本
public SampleDialog setNegativeButton(String name){
this.negativeName = name;
return this;
}
//设置确认点击事件
@OnClick(R.id.submit)
void clickSubmit(){
if(listener != null){
listener.onClick(this, true);
}
this.dismiss();
}
//设置确认取消点击事件
@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);//设置dialog,具体的样式请随意发挥,只需保证有4个控件,标题,内容文本,确认按钮,取消按钮
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,需在实际使用中实现
public interface OnCloseListener{
void onClick(Dialog dialog, boolean confirm);
}
}
实现的例子
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();//关闭dialog
}
}
});
dialog2.setPositiveButton("是!");
dialog2.setNegativeButton("我点错啦!");
dialog2.show();
补充两个内容,dialog的THEME,以及 animation 效果
values/styles.xml
<style name="dialog" parent="@android:style/Theme.Dialog">
<item name="android:windowFrame">@null</item>
<!--边框-->
<item name="android:windowIsFloating">true</item>
<!--是否浮现在activity之上-->
<item name="android:windowIsTranslucent">false</item>
<!--半透明-->
<item name="android:windowNoTitle">true</item>
<!--无标题-->
<item name="android:windowBackground">@android:color/transparent</item>
<!--背景透明-->
<item name="android:backgroundDimEnabled">true</item>
<!--模糊-->
</style>
<style name="dialogWindowAnim" mce_bogus="1" parent="android:Animation">
<item name="android:windowEnterAnimation">@anim/dialog_enter_anim</item>
<item name="android:windowExitAnimation">@anim/dialog_exit_anim</item>
</style>
动画
动画:1 anim/dialog_enter_anim
<?xml version="1.0" encoding="utf-8"?>
