Question

将webview添加到活动时，它似乎接管了整个活动。我想要的是一个小的webview和一些按钮，但是当我改变webview的大小时，它几乎没有什么区别。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="fill_parent" android:layout_width="fill_parent">

    <WebView
        android:id="@+id/webview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        />

</LinearLayout>

这是java

import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;


public class Tab3Activity extends Activity
{

    private WebView mWebview ;
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tab3);


        mWebview = new WebView(this);

        mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript

        final Activity activity = this;

        mWebview.setWebViewClient(new WebViewClient()
        {
            public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
            {
                Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();



            }
        });
        mWebview.setWebChromeClient(new WebChromeClient());
        mWebview.clearCache(true);
        mWebview.getSettings().setUserAgentString("Android WebView");
        mWebview.loadUrl(MainActivity.MapLocation);
        setContentView(mWebview);

    }
}

Answer 1

请尝试按照您的要求维护 layout_weight 。

SELECT TOP 1
    vm.EventID,
    vmm.VotingMatrixID,
    PersonAcceptedCount = SUM( CAST( vmm.IsAccepted AS INT) )

FROM    VotingMatrixMember vmm

JOIN    VotingMatrix vm
    ON vmm.VotingMatrixID = vm.ID

WHERE vm.EventID = 'abbe3077-24de-45d8-ac04-13dba97c1567'
    AND vm.Deleted = 0
    AND vmm.Deleted = 0

GROUP BY vm.EventID, vmm.VotingMatrixID

ORDER BY PersonAcceptedCount DESC

这可以帮助你。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    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="com.demo.MainActivity">

    <WebView
        android:id="@+id/webview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" >

    </WebView>

    <Button
        android:layout_below="@+id/webview"
        android:text="Button"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_x="154dp"
        android:layout_y="431dp"
        android:gravity="center"
        android:id="@+id/button" />

</RelativeLayout>

Android Webview和其他按钮一起使用
