In the development process of android application, I have used fragment for rapid development, we know iframe in java web. At this time, fragment has this purpose.
This fragment is android.support.v4.app.Fragmet
1. Define the basic BaseFragmentActivity
import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.Handler;
import android.os.IBinder;
import android.os.Message;
import android.support.v4.app.FragmentActivity;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.widget.Toast;
public abstract class BaseFragmentActivity extends FragmentActivity implements OnClickListener{
protected boolean savedState = false;
protected CommandListener commandlistener; //It is very important to pass the command in the activity to the fragment
/********************************************/
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate (savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
}
/***********************************************/
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(commandlistener!=null){
commandlistener.execute(v);
}
}
public void setCommandlistener(CommandListener commandlistener) {
this.commandlistener = commandlistener;
}
public interface CommandListener
{
public void execute(View v);
}
}
Second, define your baselayout layout file
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> </LinearLayout>
3. Define BaseFragment
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class BaseFragment extends Fragment{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
return inflater.inflate(R.layout.baselayout, container, false);
}
}
Fourth, define the main interface fragment_main of the application
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/control_popuplay"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#eee"
android:orientation="vertical" >
<include
android:id="@+id/fragment_main_top"
android:layout_width="match_parent"
android:layout_height="@dimen/title_height"
android:layout_alignParentTop="true"
layout="@layout/title_view" />
<include
android:id="@+id/bottom"
android:layout_width="match_parent"
android:layout_height="55dp"
android:layout_alignParentBottom="true"
layout="@layout/bottom_view" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_above="@id/bottom"
android:layout_below="@+id/fragment_main_top"
android:orientation="vertical" >
<fragment
android:id="@+id/mainfragment"
android:name="com.company.waiqing.activity.fragments.BaseFragment"
android:layout_width="fill_parent"
android:layout_height="match_parent" />
</LinearLayout>
</RelativeLayout>
As can be seen from the above code, the main interface at this time
The effect diagram is as follows:
Five, define your own BaseMainActivity
import android.content.Context;
import android.graphics.drawable.BitmapDrawable;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.util.DisplayMetrics;
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnTouchListener;
import android.view.ViewGroup.LayoutParams;
import android.view.WindowManager;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.PopupWindow;
import android.widget.RelativeLayout;
import android.widget.TextView;
import android.widget.Toast;
public abstract class BaseMainActivity extends BaseFragmentActivity {
protected ImageView left_button; //The button on the left side of the header bar
protected TextView title; //Title of the header bar
protected ImageView rightbutton; //The right button of the header bar
protected RelativeLayout bottom; //The layout of the bottom bar
private Popup_holder holder; //Popup box
protected PopupWindow window;
@Override
public boolean dispatchKeyEvent(KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_UP
&& event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
BaseMainActivity.this.finish();
return true;
}
if (event.getAction() == KeyEvent.ACTION_DOWN
&& event.getKeyCode() == KeyEvent.KEYCODE_MENU) {
return true;
}
return super.dispatchKeyEvent(event); // Press other buttons, call the parent class for default processing
}
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate (savedInstanceState);
//Open Activity to hide the soft keyboard;
getWindow().setSoftInputMode( WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
setContentView(R.layout.fragment_main);
Logger.i("test", "initUI");
initUI ();
initTitle();
run();
initFragment(); // initialize fragment
}
private void initUI() {
bottom=(RelativeLayout) findViewById(R.id.bottom);
}
public abstract void run();
protected void initTitle() {
left_button = (ImageView) findViewById(R.id.iv_left_button);
title = (TextView) findViewById(R.id.title_text);
rightbutton = (ImageView) findViewById(R.id.iv_right_button);
left_button.setOnClickListener(topviewlisterner);
rightbutton.setOnClickListener(topviewlisterner);
// back.setImageResource(R.drawable.back_icon);
// back.setOnClickListener(new OnClickListener() {
//
// @Override
// public void onClick(View v) {
// // TODO Auto-generated method stub
// finish();
// }
// });
}
private void initFragment() {
Logger.i("test", "initFragment");
CommonFragment f = (CommonFragment) setFragment();
Logger.i("test", "status:" + savedState);
if (f != null) {
f.setRefreshListener(this);
fragmentchage(f);
}
}
// set the middle fragment
protected Fragment setFragment() {
return null;
}
// Set the current fragment interface
private void fragmentchage(Fragment newFragment) {
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentTransaction fragmentTransaction = fragmentManager
.beginTransaction();
fragmentTransaction.replace(R.id.mainfragment, newFragment);
fragmentTransaction.commit();
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
// FragmentManager fragmentManager = getSupportFragmentManager();
// Logger.i("test", fragmentManager.getBackStackEntryCount() + "");
// fragmentManager.popBackStack();
super.onPause();
}
//Top button listener, here you can process the top button
OnClickListener topviewlisterner=new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
// make a popup
case R.id.iv_left_button:
initControlPopupView (v);
break;
case R.id.iv_right_button:
BaseMainActivity.this.finish();
break;
}
}
};
}
Six, define the basic CommonFragment
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.ComponentName;
import android.content.Intent;
import android.content.IntentFilter;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.Handler;
import android.os.IBinder;
import android.os.Message;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.util.Log;
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
/**
*
* @author arrau
* The commandlistener must be implemented, which is used to receive commands from the main interface
*/
public abstract class CommonFragment extends Fragment implements CommandListener{
protected BaseFragmentActivity context;
protected DestoryListener destorylistener;
protected View view;
@Override
public void onAttach(Activity activity) {
// TODO Auto-generated method stub
super.onAttach(activity);
Logger.i(log, "onAttach");
context = (BaseFragmentActivity) activity;
}
public void setFragmentContentView(int layout) {
view = LayoutInflater.from(context).inflate(layout, null);
context.setCommandlistener(this);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
Logger.i(log, "onCreateView");
return view;
}
public FragmentManager getSupportFragmentManager() {
return context.getSupportFragmentManager();
}
public View findViewById(int id) {
return view.findViewById(id);
}
public FragmentActivity getContext() {
return context;
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
if(destorylistener!=null)
{
destorylistener.FragmentDestory(); //When the fragment exits, let the activity exit
}
super.onDestroy ();
}
@Override
public void onPause() {
// TODO Auto-generated method stub
Logger.i(log, "onPause");
super.onPause();
}
@Override
public void onResume() {
// TODO Auto-generated method stub
Logger.i(log, "onResume");
super.onResume();
}
@Override
public void onStart() {
// TODO Auto-generated method stub
Logger.i(log, "onStart");
super.onStart();
}
@Override
public void onStop() {
// TODO Auto-generated method stub
Logger.i(log, "onStop");
super.onStop();
}
@Override
public void onDestroyView() {
// TODO Auto-generated method stub
Logger.i(log, "move to other view");
super.onDestroyView ();
}
@Override
public void execute(View v) {
// TODO Auto-generated method stub
}
//fragment destruction notification
public interface DestoryListener
{
public void FragmentDestory();
}
public DestoryListener getDestorylistener() {
return destorylistener;
}
public void setDestorylistener(DestoryListener destorylistener) {
this.destorylistener = destorylistener;
}
}
7. How to use
Some people may ask, with so much code above, I might as well write one activity one by one. My point is that although there is a lot of code above, if there are a lot of interfaces, then a lot of time can be saved for the convenience of future development.
In the future, each activity must inherit BaseMainActivity
ClientPoolActivity extends BaseMainActivity{
@Override
public void run() {
// TODO Auto-generated method stub
title.setText("Client Pool");
}
@Override
protected Fragment setFragment() {
// TODO Auto-generated method stub
ClientPoolFragment cf=new ClientPoolFragment();
return cf;
}
}
Each fragment must inherit ClientNewCreateFragment
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.LinearLayout;
import android.widget.TextView;
import com.company.core.utils.IntentUtil;
public class ClientNewCreateFragment extends CommonFragment{
private Client_Holder holder;
private ClickListener clistener;
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate (savedInstanceState);
holder=new Client_Holder();
clistener=new ClickListener();
setFragmentContentView(R.layout.fragment_client_newcreate);//The layout of the middle part
holder.t_company=(LinearLayout)findViewById(R.id.fragment_client_newcreate_companylin);
holder.t_person=(LinearLayout)findViewById(R.id.fragment_client_newcreate_personlin);
holder.t_company.setOnClickListener(clistener);
holder.t_person.setOnClickListener(clistener);
}
private class Client_Holder{
LinearLayout t_company,t_person;
}
private class ClickListener implements OnClickListener{
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
}
//This is the view after the main interface has been monitored, and it is BaseMainActivity that passes the button event over
@Override
public void execute(View v) {
// TODO Auto-generated method stub
}
}
At this time, the header bar does not need to be configured by the developer in the future. If there is a return, then it has been configured after inheriting this.
