我试着以编程方式插入的WebView到我的code [英] Im trying to programmatically insert a WebView into my Code
问题描述
我有一个连接到它的点击听者surfaceview。
I have a surfaceview with a click listener attached to it.
当我点击它，它缩小到一半的宽度和高度的一半......，并通过其放置在右下角：
When i click it, it shrinks it to half the width and half the Height... and places it in the Lower Right Corner via:
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
getWindowManager().getDefaultDisplay().getWidth()/2,
getWindowManager().getDefaultDisplay().getHeight()/2
);
rlp.setMargins(
getWindowManager().getDefaultDisplay().getWidth()/2,
getWindowManager().getDefaultDisplay().getHeight()/2,
0,
0);
它的工作原理为目的，但我想将它背后一个动态web视图。
It works as intended, but i want to place behind it Dynamically a webView.
我想：
WebView wv = makeWebView();
//makeWebView(); is a method of my mainActivity, which simple does.
private Webview makeWebView(){ return new WebView(this); }
我似乎无法得到它背后一切虽然。难道我做错了什么？
I cant seem to get it to be behind everything else though. Am i doing something wrong?
我的XML：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/RR1"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<LinearLayout
android:id="@+id/LL1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<SurfaceView
android:id="@+id/surfaceView1"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</RelativeLayout>
我MainActivity：
my MainActivity:
package com.example.testfortim;
import android.os.Bundle;
import android.app.Activity;
import android.graphics.Color;
import android.view.Gravity;
import android.view.Menu;
import android.view.SurfaceView;
import android.view.View;
import android.view.View.OnClickListener;
import android.webkit.WebView;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//SurfaceView sv = new SurfaceView();
SurfaceView sv = (SurfaceView)findViewById(R.id.surfaceView1);
sv.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
LinearLayout ll = (LinearLayout)findViewById(R.id.LL1);
//LinearLayout.LayoutParams llp = (LinearLayout.LayoutParams)ll.getLayoutParams();
//RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(ll.getLayoutParams().width/2,ll.getLayoutParams().height/2);//(RelativeLayout.LayoutParams)ll.getLayoutParams();
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
getWindowManager().getDefaultDisplay().getWidth()/2,
getWindowManager().getDefaultDisplay().getHeight()/2
);
rlp.setMargins(getWindowManager().getDefaultDisplay().getWidth()/2, getWindowManager().getDefaultDisplay().getHeight()/2, 0, 0);
ll.setLayoutParams(rlp);
WebView wv = makeWebView();
//wv.setBackgroundColor(0);
//wv.setBackgroundResource(R.color.Blue);
//wv.setBackgroundResource(Color.BLUE);
wv.loadData("<html><body>TEST</body></html>", "text/html", "utf-8");
RelativeLayout rl = (RelativeLayout)findViewById(R.id.RR1);
//rl.addView(wv);
//ll.addView(wv);
}
});
}
protected WebView makeWebView() {
return new WebView(this);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
我调整的线性布局和感动的是，这样的web视图将需要的地方放置在RR1，从我收集。我一直在寻找在不同的文档，它要么wasnt完全是IW作为找或者通过随机性，我只是didnt抓住它。
I resized the Linear Layout and moved that, so the Webview would need to be placed somewhere in RR1, from what i gather. I was looking at various documentation, and it either wasnt quite what iw as looking for or MAYBE by randomness, i just didnt grasp it.
你有想法，这是如何做到的呢？
Do you have ideas as to how this is accomplished?
一点题外话：我不知道为什么onCreateOptionMenu方法是存在的。我不使用它的计划，并会prolly最终删除。
As a sidenote: I have no idea why the onCreateOptionMenu method is there. I dont plan on using it, and will prolly end up removing it.
推荐答案
尝试 rl.addView（WV，0）
将这样的伎俩：）
Try rl.addView(wv, 0);
will do the trick :)
