我想创建自己的标签,我想拥有自己的布局
假设我想要这个结果
但原始标签看起来像
有没有办法创建自己的标签布局?

查看滑动标签示例代码:https://developer.android.com/samples/SlidingTabsBasic/index.html
并根据需要进行修改

观看Android Dev团队的this video,了解如何使用滑动标签
如果你想动态编辑页面的布局,我得到了一个方便的课程:
创建名为SmartFragmentStatePagerAdapter.java的文件并输入以下代码:
package com.package.name;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;
import android.util.SparseArray;
import android.view.ViewGroup;
/*
Extension of FragmentStatePagerAdapter which intelligently caches
all active fragments and manages the fragment lifecycles.
Usage involves extending from SmartFragmentStatePagerAdapter as you would any other PagerAdapter.
*/
public abstract class SmartFragmentStatePagerAdapter extends FragmentStatePagerAdapter {
// Sparse array to keep track of registered fragments in memory
private SparseArray<Fragment> registeredFragments = new SparseArray<Fragment>();
public SmartFragmentStatePagerAdapter(FragmentManager fragmentManager) {
super(fragmentManager);
}
// Register the fragment when the item is instantiated
@Override
public Object instantiateItem(ViewGroup container, int position) {
Fragment fragment = (Fragment) super.instantiateItem(container, position);
registeredFragments.put(position, fragment);
return fragment;
}
// Unregister when the item is inactive
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
registeredFragments.remove(position);
super.destroyItem(container, position, object);
}
// Returns the fragment for the position (if instantiated)
public Fragment getRegisteredFragment(int position) {
return registeredFragments.get(position);
}
}
在PageAdapter课程中执行以下操作:
public class PageAdapter extends SmartFragmentStatePagerAdapter {
final String TAG = "PageAdapter";
ArrayList<Fragment> cards = new ArrayList<Fragment>();
private final String[] TITLES = { getResources().getString(R.string.home) , getResources().getString(R.string.second_home) , getResources().getString(R.string.third_home) , getResources().getString(R.string.fourth_home) };
FragmentManager fm = null;
public PageAdapter(FragmentManager fm) {
super(fm);
this.fm = fm;
Log.d(TAG, "Tiles are being created");
}
@Override
public int getCount() {
return TITLES.length;
}
@Override
public CharSequence getPageTitle(int position){
return TITLES[position];
}
@Override
public Fragment getItem(int position) {
Fragment card = CardFragment.newInstance(position);
Log.d(TAG, "getItem has been called");
cards.add(card);
return card;
}
}
我的CardFragment.class:
package com.package.name;
import java.util.List;
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.util.Log;
import android.util.TypedValue;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.FrameLayout;
import android.widget.FrameLayout.LayoutParams;
public class CardFragment extends Fragment{
final String TAG = "CardFragment";
ViewGroup cards = null;
FrameLayout fl = null;
static Context context;
static FragmentManager fragmentManager = null;
private static final String ARG_POSITION = "position";
private int position;
public static CardFragment newInstance(int position) {
CardFragment f = new CardFragment();
Bundle b = new Bundle();
b.putInt(ARG_POSITION, position);
f.setArguments(b);
return f;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
fragmentManager = this.getFragmentManager();
position = getArguments().getInt(ARG_POSITION);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
cards = container;
View v = null;
if(fragmentManager == null){
fragmentManager = this.getFragmentManager();
}
switch (position){
case 0:
v = inflater.inflate(R.layout.tab_home,null);
Log.d(TAG, "Layout for position " + position + " inflated");
break;
case 1:
v = inflater.inflate(R.layout.tab_second_home,null);
Log.d(TAG, "Layout for position " + position + " inflated");
break;
case 2:
v = inflater.inflate(R.layout.tab_third_home,null);
Log.d(TAG, "Layout for position " + position + " inflated");
break;
case 3:
v = inflater.inflate(R.layout.tab_fourth_home,null);
Log.d(TAG, "Layout for position " + position + " inflated");
break;
}
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
fl = new FrameLayout(getActivity());
fl.setLayoutParams(params);
final int margin = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 8, getResources()
.getDisplayMetrics());
params.setMargins(margin, margin, margin, margin);
fl.addView(v);
return fl;
}
}
最后在你的onCreate()中执行此操作:
tabs = (HorizontalScrollView)v.findViewById(R.id.tabs);
pager = (ViewPager)v.findViewById(R.id.pager);
adapter = new PageAdapter(getSupportFragmentManager());
// Initialize the ViewPager and set an adapter
pager.setAdapter(adapter);
final int pageMargin = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 2, getResources()
.getDisplayMetrics()); // The space between pages.
pager.setPageMargin(pageMargin);
// Bind the tabs to the ViewPager
tabs.setViewPager(pager);
总共将创建4个页面,因为您的TITLES包含4个字符串。 编辑CardFragment类以使用不同的布局,为方便起见,我将它们称为tab_home,tab_second_home,tab_third_home和tab_fourth_home 如果您想要卡的根布局,请使用:
Fragment card = adapter.getRegisteredFragment(pager.getCurrentItem());
if(card != null){
textView = (TextView)card.getView().findViewById(R.id.textView); // This will use the textView you are seeing on the screen of the selected page right now. Change this to any view you would like to edit
}else{
System.out.println("card is null nothing has been added to the layout!");
}

使用Android中的自定义布局自定义ActionBar
为ActionBar创建自定义布局xml文件(根据需要)
custom_actionbar.xml
<TextView
android:id="@+id/title_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:textAllCaps="true"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#fff"
android:textStyle="bold" />
<ImageView
android:id="@+id/imageView1"
android:layout_width="35dp"
android:layout_height="35dp"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_marginLeft="8dp"
android:src="@drawable/ic_launcher" />
<ImageButton
android:id="@+id/imageButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="8dp"
android:background="@null"
android:src="@android:drawable/ic_menu_rotate" />
您可以通过setCustomView()方法将此自定义视图充气到ActionBar。我们来看看下面的代码片段
ActionBar mActionBar = getActionBar();
mActionBar.setDisplayShowHomeEnabled(false);
mActionBar.setDisplayShowTitleEnabled(false);
LayoutInflater mInflater = LayoutInflater.from(this);
View mCustomView = mInflater.inflate(R.layout.custom_actionbar, null);
TextView mTitleTextView = (TextView) mCustomView.findViewById(R.id.title_text);
mTitleTextView.setText("My Own Title");
ImageButton imageButton = (ImageButton) mCustomView
.findViewById(R.id.imageButton);
imageButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), "Refresh Clicked!",
Toast.LENGTH_LONG).show();
}
});
mActionBar.setCustomView(mCustomView);
mActionBar.setDisplayShowCustomEnabled(true);

您可以在xml custom_actionbar.xml中定义任何布局。它只是一个例子
