android系统的默认对话框是黑色背景,白色边框的样式,对于android系统来说是相当漂亮的,可是与自己的项目风格不搭,所以只好想办法重写他的样式了,当然dialog是支持样式重写的
使用new Dialog(context, style).setContentView(layout);
即可定制属于自己项目的dialog
当然,这儿的style起到了至关重要的作用,要知道那个与项目不搭的白边得全靠它了
在value下新建style.xml
下面分享一下我的代码:
首先:MainActivity

protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super .onCreate(savedInstanceState); setContentView(R.layout.main); } public void dialogStyle(View v){ final Dialog d= new Dialog( this , R.style.dialog); View vv = LayoutInflater.from( this ).inflate(R.layout.dialog_test, null ); TextView delete = (TextView) vv.findViewById(R.id.delete); d.setCanceledOnTouchOutside( true ); d.setContentView(vv); d.show(); delete.setOnClickListener( new OnClickListener() { @Override public void onClick(View arg0) { // TODO Auto-generated method stub d.dismiss(); } }); } } |
然后:style
