自定义的视图图像外边框对话框？ [英] Custom dialog with Image outside boundaries of the view?

问题描述

我试图创建一个自定义对话框喜欢的这，我按照此<一个href=\"http://stackoverflow.com/questions/20258730/custom-dialog-with-close-button/29026658#29026658\">answer但改变 layout_gravity 这个的android：layout_gravity =CENTER_HORIZONTAL |顶键，它把对中心的对话框我愿意，但问题是，如果我想要把的ImageView 大它破坏了 XML ，还有对话框本身是太小了，因为我只有一个的TextView 和的EditText 所以我做错了吗？

I'm trying to create a Custom Dialog like this, I'm following this answer but changing the layout_gravity to this android:layout_gravity="center_horizontal|top" and it puts on the center of the Dialog as I want, but the thing is that if I want to put the ImageView bigger it destroys the xml, also the Dialog itself it's too small because I only have a TextView and an EditText so what I'm doing wrong?

这是我的XML。

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<FrameLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center" >

    <FrameLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="15dp" >

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:background="#fff"
            android:orientation="vertical"
            android:padding="10dp" >

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Choose the receiver"
                android:textColor="@color/blue"
                android:textSize="16dp" />

            <EditText
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="15dp"
                android:background="@drawable/edittext_style"
                android:hint="Username"
                android:padding="5dp"
                android:singleLine="true"
                android:textColorHint="@color/wallet_holo_blue_light" />

        </LinearLayout>
    </FrameLayout>

    <ImageView
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:layout_gravity="center_horizontal|top"
        android:src="@drawable/icon_mail" />
</FrameLayout>
</FrameLayout>

输出

另外，我在可绘制来把它放在对话框以创建边框roundered颜色，如果我把它放在的LinearLayout 它不会显示出来。

Also I've a Drawable to put it on the Dialog to create a border roundered with color and if I put it on LinearLayout it doesn't show up.

这是rounded_border.xml

This is the rounded_border.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
    <shape android:shape="rectangle" >
        <solid android:color="@color/white" />
        <corners android:radius="12dip" />
        <stroke
            android:width="1dip"
            android:color="@color/wallet_holo_blue_light" />
    </shape>
</item>

如果我修改的ImageView 的大小会发生这样的：

If I change the size of the ImageView happens this :

推荐答案

您可以试试这个：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:orientation="vertical">
        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="30dp">
            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical">
                <View
                    android:layout_width="match_parent"
                    android:layout_height="0dp"
                    android:layout_weight="0.5" />
                <View
                    android:layout_width="match_parent"
                    android:layout_height="0dp"
                    android:layout_weight="0.5"
                    android:background="#fff" />
            </LinearLayout>
            <ImageView
                android:layout_width="30dp"
                android:layout_height="30dp"
                android:layout_centerInParent="true"
                android:src="@drawable/icon_mail" />
        </RelativeLayout>
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:background="#fff"
            android:orientation="vertical"
            android:padding="8dp">
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Choose the receiver"
                android:textColor="@color/blue"
                android:textSize="16dp" />
            <EditText
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="15dp"
                android:background="@drawable/edittext_style"
                android:hint="Username"
                android:padding="5dp"
                android:singleLine="true"
                android:textColorHint="@color/wallet_holo_blue_light" />
        </LinearLayout>
    </LinearLayout>
</RelativeLayout>

只是重要的是你保持（在本例中30dp）与父 RelativeLayout的高度对齐的ImageView 宽度/高度。

Just important that you keep ImageView width/height (30dp in the example) aligned with parent RelativeLayout height.
