我正在尝试使用 LayoutInflater 在另一个 xml 布局中添加一个 xml 布局。但它没有显示。
请检查我的源代码。
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.webkit.WebView;
import android.widget.RelativeLayout;
public class CustomeWebView extends Activity {
RelativeLayout relLay;
WebView webview;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_new);
relLay = (RelativeLayout) findViewById(R.id.main_relLay);
LayoutInflater inflater = (LayoutInflater) getApplication()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v_child = inflater.inflate(R.layout.row, null);
relLay.addView(v_child);
}
}
主xml文件
<RelativeLayout 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" >
<ScrollView
android:id="@+id/scrollview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<RelativeLayout
android:id="@+id/main_relLay"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#0B7A3B" >
</RelativeLayout>
</ScrollView>
</RelativeLayout>
子xml文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout

android:layout_width="match_parent"
android:layout_height="match_parent"
