Analysis of Android ActionBar Clock Making Example

This article example for everyone to share Android ActionBar to make the specific code of the clock, for your reference, the specific content is as follows

1. MainActivity.java

package com.example.days19actionbar07custom;
 
import com.example.days19actionbar07custom.R;
 
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.MenuItem.OnActionExpandListener;
import android.view.View;
import android.widget.AnalogClock;
import android.widget.SearchView;
import android.widget.SearchView.OnQueryTextListener;
import android.widget.TextView;
 
public class MainActivity extends Activity {
 
 private TextView txtResult = null;
 
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
 
  txtResult = (TextView) findViewById(R.id.txtResult);
 }
 
 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  getMenuInflater().inflate(R.menu.main, menu);
 
   
  /**************searchView*****************/
  //  Pass id Find the corresponding MenuItem ( SearchView ) 
  MenuItem searchItem = menu.findItem(R.id.action_search);
 
  SearchView view = (SearchView) searchItem.getActionView();
 
  //  To SearchView Set up listening for text changes 
  view.setOnQueryTextListener(new OnQueryTextListener() {
 
   @Override
   public boolean onQueryTextSubmit(String query) {
    return false;
   }
 
   @Override
   public boolean onQueryTextChange(String newText) {
    txtResult.setText(" You are searching " + newText);
    return false;
   }
  });
   
  /************** Custom entry *****************/
   
  //  Pass id Find custom layout MenuItem
  MenuItem customItem = menu.findItem(R.id.action_custom_layout);
   
  //  Pass menuItem Adj. getActionView () method to get 1 A View Object 
  View v = customItem.getActionView();
   
  //  It can be passed through v Adj. findViewById() Method to find the corresponding control in the custom layout 
  AnalogClock acClock = (AnalogClock) v.findViewById(R.id.acClock);
   
  //  To customItem Menu entry setting Expand Collapse Listening 
  customItem.setOnActionExpandListener(new OnActionExpandListener() {
    
   /**
    *  Menu entry expanded 
    *  Returns as true The menu representing the entry can be expanded 
    * @Override
    */
   public boolean onMenuItemActionExpand(MenuItem item) {
    txtResult.setText(" The clock is unfolded ");
    return true;
   }
    
   /**
    *  Menu entry collapsed 
    *  Returns as true The menu representing the entry can be collapsed 
    * @Override
    */
   public boolean onMenuItemActionCollapse(MenuItem item) {
    txtResult.setText(" The clock is folded ");
    return true;
   }
  });
  return true;
 }
 
}

2. main.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
 
 <item
  android:id="@+id/action_search"
  android:orderInCategory="100"
  android:actionViewClass="android.widget.SearchView"
  android:showAsAction="always"
  android:title="@string/it_search"/>
 
 <item
  android:id="@+id/action_custom_layout"
  android:actionLayout="@layout/my_layout"
  android:orderInCategory="100"
  android:icon="@drawable/ic_launcher"
  android:showAsAction="always|collapseActionView"
  android:title="layout"/>
 
</menu>

3. activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:paddingBottom="@dimen/activity_vertical_margin"
 android:paddingLeft="@dimen/activity_horizontal_margin"
 android:paddingRight="@dimen/activity_horizontal_margin"
 android:paddingTop="@dimen/activity_vertical_margin"
 tools:context=".MainActivity" >
 
 <TextView
  android:id="@+id/txtResult"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:text="@string/hello_world" />
 
</RelativeLayout>

4. my_layout.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:paddingBottom="@dimen/activity_vertical_margin"
 android:paddingLeft="@dimen/activity_horizontal_margin"
 android:paddingRight="@dimen/activity_horizontal_margin"
 android:paddingTop="@dimen/activity_vertical_margin"
 tools:context=".MainActivity" >
 
 <AnalogClock
  android:id="@+id/acClock"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:text="@string/hello_world" />
 
</RelativeLayout>

After the article, I also shared the tutorial on the use of Android ActionBar, which can be used for reference.

The above is the whole content of this article, hoping to help everyone learn Android software programming.
