cathome 猫家 开发日记-弹窗

为什么android 和ios 的弹窗都做的灵活性不高？

android自带的连个满宽都要自己写代码来实现。 真是无聊。

样式

<!--popupwindow -->
    <style name="Theme.Light.Dialog" parent="android:style/Theme.Dialog">
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:scrollHorizontally">true</item>
    </style>

继承自 AppCompatDialog

import com.android.linson.catshome.R;

public abstract class LSUIPopupWindow extends AppCompatDialog
{
    protected int mHeight=-1;
    protected RelativeLayout mContentLayout;
    protected String mTitle="";
    protected TextView mTVTitle;
    protected LinearLayout mMenuLayout;
    protected Button mBtn_cancel;
    protected Button mBtn_submit;
    private static int mWindowStyle=R.style.Theme_Light_Dialog;

    public LSUIPopupWindow(Context context, int heightdp, String title)
    {
        super(context,mWindowStyle);
        mHeight=heightdp;
        mTitle=title;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        SetupFullWindow();
        setContentView(R.layout.lsuipopupwindow);
        mContentLayout=findViewById(R.id.popupcontenct);
        mTVTitle=findViewById(R.id.popuptitle);
        mTVTitle.setText(mTitle);
        mMenuLayout=findViewById(R.id.popupmenu);
        mBtn_cancel=findViewById(R.id.btn_cancel);
        mBtn_submit=findViewById(R.id.btn_submit);
        mBtn_submit.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                OnClickSubmit(v);
            }
        });
        mBtn_cancel.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                dismiss();//windowmanager.removeview.......
            }
        });

        OnBaseCreated(savedInstanceState);
    }

    public abstract void OnClickSubmit(View v);

    public abstract void OnBaseCreated(Bundle savedInstanceState);

    private void SetupFullWindow()
    {
        Window window= getWindow();
        window.setGravity(Gravity.BOTTOM);

        // window.setWindowAnimations(R.style.dialogStyle);
        window.getDecorView().setPadding(0, 0, 0, 0);

        WindowManager.LayoutParams lp = window.getAttributes();
        lp.width = WindowManager.LayoutParams.MATCH_PARENT;
        lp.height =mHeight;
        window.setAttributes(lp);
    }
}

使用，基类做成虚类，主要目的是让派生类强制实现虚方法。其实基类非虚类更合理。不过无所谓了。

testpopup ab =new testpopup(this,400,"hi");
        ab.show();

public static class testpopup extends LSUIPopupWindow
    {
        public testpopup(Context context, int heightdp, String title)
        {
            super(context, heightdp, title);
        }

        @Override
        public void OnClickSubmit(View v)
        {
            dismiss();
        }

        @Override
        public void OnBaseCreated(Bundle savedInstanceState)
        {

        }
    }
