Android Dialog無法填滿螢幕寬度問題解決

標籤：

就是將上面的自訂布局放到一個Dialog裡面，布局xml

<?xml version="1.0" encoding="UTF-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="155dp"    android:background="@color/transparent"    android:paddingLeft="0dp"    android:paddingRight="0dp"    android:paddingBottom="10dp"    android:paddingTop="0dp">    <LinearLayout android:id="@+id/sharelayout"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="@drawable/share_dialog_bg"        android:orientation="vertical"        android:padding="0dp"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp">        <TextView android:id="@+id/wxtext"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:text="好友"            android:textSize="16sp"            android:textColor="@color/head_text"            android:gravity="center"            android:paddingTop="12dp"            android:paddingBottom="12dp"/>        <View            android:layout_width="fill_parent"            android:layout_height="1px"            android:layout_alignParentBottom="true"            android:background="#d1d1d1" />        <TextView android:id="@+id/wxfriend"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:text="朋友圈"            android:textSize="16sp"            android:textColor="@color/head_text"            android:gravity="center"            android:paddingTop="12dp"            android:paddingBottom="12dp"/>    </LinearLayout>    <TextView android:id="@+id/sharecancle"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="取消"        android:textSize="16sp"        android:textColor="#FF4E17"        android:background="@drawable/share_dialog_bg"        android:layout_marginTop="10dp"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"        android:gravity="center"        android:paddingTop="12dp"        android:paddingBottom="12dp"        android:layout_below="@id/sharelayout"/></RelativeLayout>

然後

View dialogview = LayoutInflater.from(activity).inflate(R.layout.customsharelayout, null);

shareDialog = new Dialog(activity, R.style.dialog_untran);shareDialog.setContentView(dialogview);Window window = shareDialog.getWindow();WindowManager.LayoutParams windowparams = window.getAttributes();window.setGravity(Gravity.BOTTOM);  Rect rect = new Rect();  View view1 = window.getDecorView();  view1.getWindowVisibleDisplayFrame(rect);  windowparams.height = DensityUtil.dip2px(activity, 155);  windowparams.width = SettingUtil.getDisplaywidthPixels();  window.setWindowAnimations(R.style.AnimationDialog);  window.setBackgroundDrawableResource(android.R.color.transparent);  window.setAttributes((android.view.WindowManager.LayoutParams) windowparams);  shareDialog.show();

Animation設定

<style name="AnimationDialog">        <item name="android:windowEnterAnimation">@anim/custom_dialog_enter</item>        <item name="android:windowExitAnimation">@anim/custom_dialog_exit</item>    </style>

custom_dialog_enter.xml

<?xml version="1.0" encoding="UTF-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"    android:interpolator="@android:anim/decelerate_interpolator">    <translate        android:duration="@android:integer/config_shortAnimTime"        android:fromYDelta="100%p"        android:toYDelta="0" />    <alpha        android:duration="@android:integer/config_shortAnimTime"        android:fromAlpha="0.0"        android:toAlpha="1.0" /></set>

主意是使用dialog設定在底部，並且寬度和padding值根據layout的布局來定。
