仿抖音注册Dialog实现

今天将仿抖音注册界面完成后接着便将注册界面实现了，这里利用的是Dialog实现的

效果图

接下来介绍如何实现底部弹出Dialog

1.首先编写动画文件

<!--tranlate_dialog_in.xml--> <?xml version="1.0" encoding="utf-8"?> <translate xmlns:android="http://schemas.android.com/apk/res/android" android:duration="200" android:fromXDelta="0" android:fromYDelta="100%" android:toXDelta="0" android:toYDelta="0"> </translate> <!--tranlate_dialog_out.xml--> <?xml version="1.0" encoding="utf-8"?> <translate xmlns:android="http://schemas.android.com/apk/res/android" android:duration="200" android:fromXDelta="0" android:fromYDelta="0" android:toXDelta="0" android:toYDelta="100%"> </translate> 

2.编写Dialog的style

<style name="BottomDialog" parent="@style/Base.V7.Theme.AppCompat.Light.Dialog"> <item name="android:windowNoTitle">true</item> <item name="android:windowBackground">@android:color/transparent</item> </style> <style name="BottomDialog.Animation" parent="Animation.AppCompat.Dialog"> <item name="android:windowEnterAnimation">@anim/tranlate_dialog_in</item> <item name="android:windowExitAnimation">@anim/tranlate_dialog_out</item> </style> 

3.代码中实现

 Dialog bottomDialog = new Dialog(context, R.style.BottomDialog); bottomDialog.setContentView(contentView); ViewGroup.LayoutParams layoutParams = contentView.getLayoutParams(); layoutParams.width = context.getResources().getDisplayMetrics().widthPixels; layoutParams.height=context.getResources().getDisplayMetrics().heightPixels; contentView.setLayoutParams(layoutParams); bottomDialog.getWindow().setGravity(Gravity.BOTTOM); bottomDialog.getWindow().setWindowAnimations(R.style.BottomDialog_Animation); bottomDialog.show();
