Question

在我的自定义对话框中，我试图让我的复选框保留在我的滚动视图下方，但它无法正常工作。我尝试在xml的scrollview下添加复选框，但每次运行应用时都不会显示。为了使复选框保留在对话框的底部（滚动视图下方），并且滚动时不能成为滚动视图的一部分，需要做些什么？我根本不希望我的复选框滚动滚动视图。

的java

LayoutInflater inflater = LayoutInflater.from(this);
View dialog_layout = inflater.inflate(R.layout.fragment_overlay, (ViewGroup) findViewById(R.id.Overlay_linearLayout));
AlertDialog.Builder db = new AlertDialog.Builder(this);
db.setView(dialog_layout);
db.setPositiveButton("OK", new DialogInterface.OnClickListener() {
});
db.show();

XML

Answer 1

尝试在新checkbox内设置ScrolView和LinearLayout，并将checkbox放在ScrollView之外，如下所示：

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ScrollView android:id="@+id/Overlay_scrollView"
                xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="fill_parent"
                android:layout_height="0dp"
                android:layout_weight="1">

        <TableLayout android:id="@+id/Overlay_tableLayout"
                     xmlns:android="http://schemas.android.com/apk/res/android"
                     android:layout_width="fill_parent"
                     android:layout_height="wrap_content"
                     android:weightSum="1.0">

                <ImageView
                    android:layout_width="0px"
                    android:layout_height="80dp"
                    android:layout_weight="0.3"
                    android:src="@drawable/ic_launcher"/>

                <TextView
                    android:id="@+id/MapOverlay_textView0"
                    android:layout_width="0px"
                    android:layout_weight="0.7"
                    android:text="tion0"/>


                <ImageView
                    android:layout_width="0px"
                    android:layout_height="80dp"
                    android:layout_weight="0.3"
                    android:src="@drawable/ic_launcher"/>

                <TextView
                    android:id="@+id/MapOverlay_textView1"
                    android:layout_width="0px"
                    android:layout_weight="0.7"
                    android:text="dada"/>


                <ImageView
                    android:layout_width="0px"
                    android:layout_height="80dp"
                    android:layout_weight="0.3"
                    android:src="@drawable/ic_launcher"/>

                <TextView
                    android:id="@+id/MapOverlay_textView2"
                    android:layout_width="0px"
                    android:layout_weight="0.7"
                    android:text="ruction2"/>


                <ImageView
                    android:layout_width="0px"
                    android:layout_height="80dp"
                    android:layout_weight="0.3"
                    android:src="@drawable/ic_launcher"/>

                <TextView
                    android:id="@+id/MapOverlay_textView3"
                    style="@android:style/TextAppearance.Medium"
                    android:layout_width="0px"
                    android:layout_weight="0.7"
                    android:text="_instruction3"/>


        </TableLayout>
    </ScrollView>

    <CheckBox
        android:id="@+id/skip"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Don't show this again"/>
</LinearLayout>

如何夸大xml文件并将其设置为dialog

LayoutInflater inflater = getLayoutInflater();
View dialoglayout = inflater.inflate(R.layout.dialog_layout, null);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(dialoglayout);
builder.show();

Answer 2

尝试使用此布局文件。这是你的xml文件，有一些修改。

DECLARE @x XML='<root><Test name="checkTest">TestValue</Test></root>';
SELECT @x;

--This is the XML string in base64
DECLARE @xBase64 VARCHAR(MAX)='PHJvb3Q+DQogIDxUZXN0IG5hbWU9ImNoZWNrVGVzdCI+VGVzdFZhbHVlPC9UZXN0Pg0KPC9yb290Pg==';

CREATE TABLE #testBase64(ID INT, SomeBLOB VARBINARY(MAX));
INSERT INTO #testBase64 VALUES(1,CAST(@xBase64 AS VARBINARY(MAX)));

SELECT ID 
      ,SomeBLOB                          AS TheBLOB_as_HexString
      ,CAST(SomeBLOB AS VARCHAR(MAX))    AS TheBLOB_back_to_Base64

      --taken from here: https://stackoverflow.com/a/32231832/5089204
      ,CAST(CAST(CAST(CAST(SomeBLOB AS VARCHAR(MAX)) AS XML).value('.','varbinary(max)') AS VARCHAR(MAX)) AS XML) AS Back_to_XML

FROM #testBase64;

DROP TABLE #testBase64;

CheckBox没有停留在对话框的底部
