自定义actionBar布局:标题居中,左边有返回按键
<?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="50dp" > <ImageView android:id="@+id/home" android:layout_width="25dp" android:layout_height="25dp" android:layout_marginLeft="10dp" android:clickable="true" android:scaleType="fitXY" android:layout_alignParentLeft="true" android:layout_centerVertical="true" android:src="@drawable/wd007" /> <TextView android:id="@+id/titlebar" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:gravity="center" android:text="消 息" android:textColor="@color/titlecolor" android:textSize="20sp" /> <ImageView android:id="@+id/right" android:layout_width="25dp" android:layout_height="25dp" android:layout_marginRight="10dp" android:clickable="true" android:scaleType="fitXY" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:visibility="invisible" android:src="@drawable/wd007" /> </RelativeLayout>
java文件里面使用:
package com.tuyoung.wu; import com.example.toyoung.R; import android.app.ActionBar; import android.app.Activity; import android.os.Bundle; import android.view.Gravity; import android.view.LayoutInflater; import android.view.MenuItem; import android.view.View; import android.view.View.OnClickListener; import android.view.Window; import android.widget.ImageView; public class Message extends Activity{ private ImageView back; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.activity_message); setCustomActionBar(); } private void setCustomActionBar() { ActionBar.LayoutParams lp =new ActionBar.LayoutParams(ActionBar.LayoutParams.MATCH_PARENT, ActionBar.LayoutParams.MATCH_PARENT, Gravity.CENTER); View mActionBarView = LayoutInflater.from(this).inflate(R.layout.customtitle, null); ActionBar actionBar = getActionBar(); actionBar.setCustomView(mActionBarView, lp); actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM); actionBar.setDisplayShowCustomEnabled(true); actionBar.setDisplayShowHomeEnabled(false); actionBar.setDisplayShowTitleEnabled(false); back = (ImageView) mActionBarView.findViewById(R.id.home); back.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { finish(); } }); } }
分割间距:
<ImageView android1:layout_marginTop="20dp" android:layout_width="match_parent" android:layout_height="1dp" android:background="#ffffff" />
