使用FragmentTabHost和ViewPager实现仿微信主界面策划

最近看到很多界面主页都差不多,决定研究研究写出来,以后直接拿来用,不做代码的轮子,多总结,多学习

还是废话少说,先上图

介绍一下我的代码:

首先是布局文件:

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

     <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />

    <android.support.v4.app.FragmentTabHost
        android:id="@android:id/tabhost"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/black" >

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:layout_weight="0" />
    </android.support.v4.app.FragmentTabHost>

</LinearLayout>

当然如果你想让底部的tab放在上面的话,可以把viewPager和FragmentTabHost位置换一下,以上就是主界面了,比较简单没什么好说的,给个小技巧吧,shift+ctrl+T可以查找你想要的包,例如输入viewPager,直接粘android.support.v4.view.ViewPager就可以了,比较方便

下面就是MainActivity了:

package com.sdufe.thea.framework;

import java.util.ArrayList;
import java.util.List;
import java.util.zip.Inflater;

import android.os.Bundle;
import android.R.integer;
import android.annotation.SuppressLint;

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTabHost;
import android.support.v4.view.ViewPager;
import android.support.v4.view.ViewPager.OnPageChangeListener;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TabHost.OnTabChangeListener;
import android.widget.TabHost.TabSpec;
import android.widget.TabWidget;
import android.widget.TextView;

public class MainActivity extends FragmentActivity implements
		OnPageChangeListener, OnTabChangeListener {

	private FragmentTabHost mTabHost;
	private LayoutInflater layoutInflater;
	private Class fragmentArray[] = { Fragment1.class, Fragment.class,
			Fragment3.class, Fragment4.class };
	private int imageViewArray[] = { R.drawable.mywork, R.drawable.mypatient,
			R.drawable.infusion, R.drawable.personal };
	private String textViewArray[] = { "工作", "病人", "互动", "个人中心" };
	private List<Fragment> list = new ArrayList<Fragment>();
	private ViewPager vp;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main_tab_layout);

		initView();
		initPage();
	}

	/**
	 * 控件初始化
	 */
	private void initView() {
		vp = (ViewPager) findViewById(R.id.pager);
		vp.setOnPageChangeListener(this);
		layoutInflater = LayoutInflater.from(this);
		mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
		mTabHost.setup(this, getSupportFragmentManager(), R.id.pager);
		mTabHost.setOnTabChangedListener(this);

		int count = textViewArray.length;

		for (int i = 0; i < count; i++) {
			TabSpec tabSpec = mTabHost.newTabSpec(textViewArray[i])
					.setIndicator(getTabItemView(i));
			mTabHost.addTab(tabSpec, fragmentArray[i], null);
			mTabHost.setTag(i);
		}
	}

	/**
	 * 初始化Fragment
	 */
	private void initPage() {
		Fragment1 fragment1 = new Fragment1();
		Fragment2 fragment2 = new Fragment2();
		Fragment3 fragment3 = new Fragment3();
		Fragment4 fragment4 = new Fragment4();
		list.add(fragment1);
		list.add(fragment2);
		list.add(fragment3);
		list.add(fragment4);
		vp.setAdapter(new MyFragmentAdapter(getSupportFragmentManager(), list));
	}

	private View getTabItemView(int i) {
		View view = layoutInflater.inflate(R.layout.tab_content, null);
		ImageView mImageView = (ImageView) view
				.findViewById(R.id.tab_imageview);
		TextView mTextView = (TextView) view.findViewById(R.id.tab_textview);
		mImageView.setBackgroundResource(imageViewArray[i]);
		mTextView.setText(textViewArray[i]);
		return view;
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

	@Override
	public void onPageScrollStateChanged(int arg0) {

	}

	@Override
	public void onPageScrolled(int arg0, float arg1, int arg2) {

	}

	@Override
	public void onPageSelected(int arg0) {
		TabWidget widget = mTabHost.getTabWidget();
		int oldFocusability = widget.getDescendantFocusability();
		widget.setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);
		mTabHost.setCurrentTab(arg0);
		widget.setDescendantFocusability(oldFocusability);
		mTabHost.getTabWidget().getChildAt(arg0) 
				.setBackgroundResource(R.drawable.selector_tab_background);
	}

	@Override
	public void onTabChanged(String tabId) {
		int position = mTabHost.getCurrentTab();
		vp.setCurrentItem(position);
	}

}

代码相对来说比较简单,下面的就不贴了
