在为Android应用设计UI时,我遇到了以下问题。我想将抽屉的ListView中的项目与底部对齐。我是android开发的新手。任何帮助将不胜感激。
这是我的抽屉代码
<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_gravity="start"
android:background="#E0E0E0"
android:choiceMode="singleChoice"
android:dividerHeight="1dp" />
</android.support.v4.widget.DrawerLayout>
这是我在ListView
中充气的三个xml文件1)profile_view.xml
<ImageView
android:id="@+id/ivProfile"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingRight="10dp"
android:src="@drawable/sneha_lata" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:orientation="vertical" >
<TextView
android:id="@+id/tvName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Sneha Lata"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textStyle="bold" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:orientation="horizontal" >
<TextView
android:id="@+id/tvEdit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Edit Profile"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textStyle="" />
<ImageView
android:id="@+id/ivForward"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/forward" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
2)emergency_view.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="20dp"
android:paddingTop="20dp" >
<TextView
android:id="@+id/tvManage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="40dp"
android:text="Manage Emergency Contacts"
android:textAppearance="?android:attr/textAppearanceMedium" />
<ImageView
android:id="@+id/ivForward"
android:layout_toRightOf="@id/tvManage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/forward" />
<TextView
android:id="@+id/tvManageText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/tvManage"
android:layout_alignParentLeft="true"
android:layout_alignRight="@id/tvManage"
android:layout_marginLeft="40dp"
android:fontFamily="sans-serif-light"
android:text="@string/tvManageText"
android:textAppearance="?android:attr/textAppearanceSmall" />
</RelativeLayout>
3) logout view
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/logout_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<Button
android:id="@+id/btnLogout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="@drawable/red_button"
android:text="Log Out"
android:textColor="#FFFFFF" />
</RelativeLayout>
即使我在我的logout_view.xml中使用了android:layout_alignParentBottom =“true”,它仍然没有在抽屉的底部对齐,但它在logout_view.xml中
这是DrawerAdapter的代码
package com.majhe.android.adapter;
import com.majhe.android.LoginActivity;
import com.majhe.android.R;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.webkit.WebView.FindListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.RelativeLayout;
public class DrawerAdapter extends ArrayAdapter<String> implements OnClickListener {
Context context;
Button btnLogout;
public DrawerAdapter(Context context) {
super(context, android.R.layout.simple_list_item_1, new String[] {
"Profile View", "Emergency View", "Logout View" });
this.context = context;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
switch (position) {
case 0:
convertView = inflater.inflate(R.layout.profile_view, null, true);
return convertView;
case 1:
convertView = inflater.inflate(R.layout.emergency_view, null,true);
return convertView;
case 2:
convertView = inflater.inflate(R.layout.logout_view, null, true);
btnLogout=(Button)convertView.findViewById(R.id.btnLogout);
btnLogout.setOnClickListener(this);
return convertView;
}
return super.getView(position, convertView, parent);
}
@Override
public void onClick(View v) {
context.startActivity(new Intent(context,LoginActivity.class));
((Activity)context).finish();
}
}
答案 0 :(得分:1)
如果我是对的,我认为你根本不需要使用ListView?用这样的东西替换你的列表视图可能有帮助
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#fff"
android:orientation="vertical"
android:paddingEnd="10dp" android:gravity="bottom">
<include layout="@layout/profile_view"/>
<include layout="@layout/emergency_view"/>
<include layout="@layout/logout_view"/>
</LinearLayout>
将{d}和layout_height
layout_weight
设置为视图中的1以填充剩余空间(最有可能是emergency_view
),以便您的logot_view将alwyas粘贴到底部
