Android 中从屏幕左下角弹出Dialog动画效果的实现代码
MainActivity代码:
importandroid.app.Dialog; importandroid.os.Bundle; importandroid.support.v7.app.AppCompatActivity; importandroid.view.Gravity; importandroid.view.LayoutInflater; importandroid.view.View; importandroid.view.Window; importandroid.view.WindowManager; publicclassMainActivityextendsAppCompatActivity{ privateViewinflate; privateDialogdialog; @Override protectedvoidonCreate(BundlesavedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } publicvoidclick(Viewview){ dialog=newDialog(this,R.style.ActionDialogStyle); //填充对话框的布局 inflate=LayoutInflater.from(this).inflate(R.layout.item_dialog,null); //初始化控件 //将布局设置给Dialog dialog.setContentView(inflate); //获取当前Activity所在的窗体 WindowdialogWindow=dialog.getWindow(); //设置Dialog从窗体底部弹出 dialogWindow.setGravity(Gravity.BOTTOM); //获得窗体的属性 WindowManager.LayoutParamslp=dialogWindow.getAttributes(); lp.y=20;//设置Dialog距离底部的距离 lp.width=WindowManager.LayoutParams.MATCH_PARENT; //将属性设置给窗体 dialogWindow.setAttributes(lp); dialog.show();//显示对话框 } }
主界面的布局:
<?xmlversion="1.0"encoding="utf-8"?> <LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="ucai.cn.dialoganimator.MainActivity"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="HelloWorld!" android:onClick="click"/> </LinearLayout>
Dialog布局:
<?xmlversion="1.0"encoding="utf-8"?> <LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical"android:layout_width="match_parent" android:layout_height="match_parent"> <ImageView android:layout_width="match_parent" android:layout_height="wrap_content" android:src="@drawable/hani_gift_1" android:layout_gravity="center"/> </LinearLayout>
styles代码:
<stylename="ActionDialogStyle"parent="@android:style/Theme.Dialog">
<!--背景透明--> <itemname="android:windowBackground">@android:color/transparent</item> <itemname="android:windowContentOverlay">@null</item> <!--浮于Activity之上--> <itemname="android:windowIsFloating">true</item> <!--边框--> <itemname="android:windowFrame">@null</item> <!--Dialog以外的区域模糊效果--> <itemname="android:backgroundDimEnabled">true</item> <!--无标题--> <itemname="android:windowNoTitle">true</item> <!--半透明--> <itemname="android:windowIsTranslucent">true</item> <!--Dialog进入及退出动画--> <itemname="android:windowAnimationStyle">@style/ActionSheetDialogAnimation</item> </style> <!--ActionSheet进出动画--> <stylename="ActionSheetDialogAnimation"parent="@android:style/Animation.Dialog"> <itemname="android:windowEnterAnimation">@anim/actionsheet_dialog_in</item> <itemname="android:windowExitAnimation">@anim/actionsheet_dialog_out</item> </style>
进入动画(左下角开始放大):
<?xmlversion="1.0"encoding="utf-8"?> <scalexmlns:android="http://schemas.android.com/apk/res/android" android:duration="1000" android:fromXScale="0" android:toXScale="100%" android:fromYScale="0" android:toYScale="100%" android:pivotX="0%" android:pivotY="100%" />
退出动画(向下移动):
<?xmlversion="1.0"encoding="utf-8"?> <translatexmlns:android="http://schemas.android.com/apk/res/android" android:duration="200" android:fromYDelta="0" android:toYDelta="100%"/>
