主要是用于dialog的內(nèi)容變化但是部分內(nèi)容不變復(fù)用方便寫的

publicclassMainDialogextendsDialogimplementsView.OnClickListener{

privateViewroot;

privateViewGroupcontainer;

privateButtonbtnObtain;

privateIWheelPickerpicker;

privateStringdata;

publicMainDialog(Contextcontext) {

super(context);

requestWindowFeature(Window.FEATURE_NO_TITLE);

getWindow().setBackgroundDrawable(newColorDrawable(Color.TRANSPARENT));

setCanceledOnTouchOutside(true);

setOnDismissListener(newOnDismissListener() {

@Override

publicvoidonDismiss(DialogInterfacedialog) {

container.removeAllViews();

}

});

//我們?yōu)閐ialog設(shè)置一個(gè)布局文件

root=getLayoutInflater().inflate(R.layout.ac_main_dialog,null);

//跟布局里面的動(dòng)態(tài)添加布局的容器

container=(ViewGroup) root.findViewById(R.id.main_dialog_container);

//公用的確認(rèn)按鈕

btnObtain=(Button) root.findViewById(R.id.btn_obtain);

btnObtain.setOnClickListener(this);

}

//復(fù)寫他的setcontentview（）方法，將我們自定義的布局添加到我們的跟容器中，這樣可以在代碼中靈活的設(shè)置了，

@Override

publicvoidsetContentView(Viewview) {

if(viewinstanceofIWheelPicker) {

picker=(IWheelPicker) view;

picker.setOnWheelChangeListener(newAbstractWheelPicker.SimpleWheelChangeListener() {

@Override

publicvoidonWheelScrollStateChanged(intstate) {

if(state!=AbstractWheelPicker.SCROLL_STATE_IDLE) {

btnObtain.setEnabled(false);

}else{

btnObtain.setEnabled(true);

}

}

@Override

publicvoidonWheelSelected(intindex,Stringdata) {

MainDialog.this.data=data;

}

});

}

container.addView(view);

super.setContentView(root);

}

@Override

publicvoidonClick(Viewv) {

switch(v.getId()) {

caseR.id.btn_obtain:

Toast.makeText(getContext(), data,Toast.LENGTH_SHORT).show();

break;

}

}
