android 仿ios 对话框已封装成工具类

对话框 在android中是一种很常见的交互提示用户的方式,但是很多产品狗都叫我们这些做android的仿ios,搞的我们android程序员很苦逼,凭什么效果老是仿ios，有没有一点情怀,不过ios在界面封装确实比android好很多,吐槽完毕,比如一种很常见的场景就是在没网的情况下 提示用户,看效果图：

在很多界面都要有提示,那么就自然而然想到了封装,而不至于在每个页面都重写一篇,话不多说直接上代码

CommonDialog.java

public class CommonDialog extends Dialog{
	 private Context context;
	 private String title;
     private ClickListenerInterface clickListenerInterface;
	public CommonDialog(Context context) {
		super(context, R.style.MyDialogStyle);
		this.context = context;
	}
	 @Override
	 protected void onCreate(Bundle savedInstanceState) {
	         super.onCreate(savedInstanceState);
	         init();
	    }
	 private void init() {
		LayoutInflater inflater =LayoutInflater.from(context);
		View view =inflater.inflate(R.layout.dialog_common, null);
		setContentView(view);
		TextView tv_ok=  (TextView) view.findViewById(R.id.tv_ok);
		tv_ok.setOnClickListener(new clickListener());
        Window dialogWindow = getWindow();
        WindowManager.LayoutParams lp = dialogWindow.getAttributes();
        DisplayMetrics d = context.getResources().getDisplayMetrics(); // 获取屏幕宽、高用
        lp.width = (int) (d.widthPixels * 0.8); // 高度设置为屏幕的0.6
        dialogWindow.setAttributes(lp);
	}
	public interface ClickListenerInterface {
		        public void doConfirm();
		   }
    public void setClicklistener(ClickListenerInterface clickListenerInterface) {
		        this.clickListenerInterface = clickListenerInterface;
		     }
	 private class clickListener implements View.OnClickListener {
		         @Override
		          public void onClick(View v) {
		              int id = v.getId();
		            switch (id) {
		             case R.id.tv_ok:
		            	 dismiss();
		                break;
		            }
	         }
	     };
}

对话框样式 style

<style name="MyDialogStyle">
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowFrame">@null</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
        <item name="android:backgroundDimEnabled">true</item>
    </style>

使用：

final CommonDialog confirmDialog = new CommonDialog(getActivity());
            confirmDialog.show();
            confirmDialog.setClicklistener(new CommonDialog.ClickListenerInterface() {
            @Override
            public void doConfirm() {}
            });
