自定义Title标题样式

我们在开发中，会对标题进行操作，全屏操作，改变标题样式等等。我们可以通过requestWindowFeature(featrueId)来实现，它的功能是启用窗体的扩展特性。参数是Window类中定义的常量。

枚举常量

1.DEFAULT_FEATURES：系统默认状态，一般不需要指定

2.FEATURE_CONTEXT_MENU：启用ContextMenu，默认该项已启用，一般无需指定

3.FEATURE_CUSTOM_TITLE：自定义标题。当需要自定义标题时必须指定。如：标题是一个按钮时

4.FEATURE_INDETERMINATE_PROGRESS：不确定的进度

5.FEATURE_LEFT_ICON：标题栏左侧的图标

6.FEATURE_NO_TITLE：吴标题

7.FEATURE_OPTIONS_PANEL：启用“选项面板”功能，默认已启用。

8.FEATURE_PROGRESS：进度指示器功能

9.FEATURE_RIGHT_ICON:标题栏右侧的图标

自定义标题样式，这里用加载条来作例子：

Main.java

package com.action;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.Window;

public class Main extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
    	super.onCreate(savedInstanceState);
    	this.requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
    	  setContentView(R.layout.main);
    	  getWindow().setFeatureInt(Window.FEATURE_INDETERMINATE_PROGRESS, R.layout.progress);
    	  setProgressBarIndeterminateVisibility(true);
    	  new Thread(runnable).start();
    }
    private Runnable runnable = new Runnable(){

		@Override
		public void run() {
			Message msg = new Message();
			try {
				Thread.sleep(1500);
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
			handler.sendMessage(msg);
			
		}
    	
    };
    Handler handler = new Handler(){
		@Override
		public void handleMessage(Message msg) {
			setProgressBarIndeterminateVisibility(false);
			super.handleMessage(msg);
		}
    	
    };
}

 progress.xml

 

 

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="wrap_content" android:layout_height="wrap_content">
	<ProgressBar android:id="@+id/progress"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:layout_gravity="center_vertical" style="?android:attr/progressBarStyleSmallTitle">
	</ProgressBar>
</LinearLayout>

 

 

全屏操作：

package com.action;

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;

public class Main extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
    	super.onCreate(savedInstanceState);
    	this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    	  setContentView(R.layout.main);
    	  setProgressBarIndeterminateVisibility(true);
    }
}
