本文实例为大家分享了android FragmentTabhost导航分页展示的具体代码,供大家参考,具体内容如下
基本模板
public class MainActivity extends FragmentActivity {
private FragmentTabHost mTabHost;
private LayoutInflater mLayoutInflater;
private Class mFragmentArray[] = { Fragment1.class, Fragment2.class,
Fragment3.class, Fragment4.class, Fragment5.class };
private int mImageArray[] = { R.drawable.tab_home_btn,
R.drawable.tab_message_btn, R.drawable.tab_selfinfo_btn,
R.drawable.tab_square_btn, R.drawable.tab_more_btn };
private String mTextArray[] = { "首页", "消息", "好友", "搜索", "更多" };
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initView();
}
private void initView() {
mLayoutInflater = LayoutInflater.from(this);
// 找到TabHost
mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);
mTabHost.getTabWidget().setDividerDrawable(null);//去除分割线
// 得到fragment的个数
for (int i = 0; i < mFragmentArray.length; i++) {
// 给每个Tab按钮设置图标、文字和内容
TabSpec tabSpec = mTabHost.newTabSpec(mTextArray[i])
.setIndicator(getTabItemView(i));
// 将Tab按钮添加进Tab选项卡中
mTabHost.addTab(tabSpec, mFragmentArray[i], null);
// 设置Tab按钮的背景
mTabHost.getTabWidget().getChildAt(i)
.setBackgroundResource(R.drawable.selector_tab_background);
}
}
//给每个Tab按钮设置图标和文字
private View getTabItemView(int index) {
View view = mLayoutInflater.inflate(R.layout.tab_item_view, null);
ImageView imageView = view.findViewById(R.id.imageview);
//设置图片选择器,选中的tab改变图标
switch (index){
case 0:imageView.setImageResource(R.drawable.main_bottom_image_selector);break;
case 1:imageView.setImageResource(R.drawable.main_bottom_image_selector2);break;
case 2:imageView.setImageResource(R.drawable.main_bottom_image_selector3);break;
case 3:imageView.setImageResource(R.drawable.main_bottom_image_selector4);break;
case 4:imageView.setImageResource(R.drawable.main_bottom_image_selector5);break;
}
TextView textView = view.findViewById(R.id.textview);
textView.setText(mTextArray[index]);
//设置文本选择器,选中的tab文字高亮
textView.setTextColor(R.drawable.main_bottom_text_selector);
return view;
}
}
