Horizontal---ProgressBar

相当简单，直接贴

先看主界面布局activity_custom_progress_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" android:layout_width="fill_parent"
	android:layout_height="fill_parent" android:gravity="center">

	<Button android:text="自定义颜色进度条" android:id="@+id/color"
		android:layout_width="wrap_content" android:layout_height="wrap_content" />
	<Button android:text="自左向右的进度条" android:id="@+id/left"
		android:layout_width="wrap_content" android:layout_height="wrap_content" />

</LinearLayout>

ProgressBarMain

package com.example.progressdemo;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class ProgressBarMain extends Activity implements OnClickListener {

	/**
	 * 按钮点击进入自定义颜色的进度条页面
	 */
	private Button color;

	/**
	 * 按钮点击进入左方向进度条页面
	 */
	private Button left;

	/**
	 * 按钮点击进入右方向进度条页面
	 */
	private Button right;

	/**
	 * 按钮点击进入不定进度条页面
	 */
	private Button indeter;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_custom_progress_main);

		initProperty();
	}

	private void initProperty() {
		color = (Button) findViewById(R.id.color);
		left = (Button) findViewById(R.id.left);

		color.setOnClickListener(this);
		left.setOnClickListener(this);
	}

	@Override
	public void onClick(View v) {
		switch (v.getId()) {
		case R.id.color:
			startActivity(new Intent(this, ProgressBar_Color.class));
			break;
		case R.id.left:
			startActivity(new Intent(this, ProgressBar_Left.class));
			break;
		default:
			break;
		}
	}

}

接下来看ProgressBar_Color

package com.example.progressdemo;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.widget.ProgressBar;

public class ProgressBar_Color extends Activity {

	private ProgressBar mColor = null;

	private int mCount = 0;

	private final int HANDLER_LEFT = 1;
	private Handler mHandler = new Handler() {
		@Override
		public void handleMessage(Message msg) {
			if (msg.what == HANDLER_LEFT) {
				finish();
			}
			super.handleMessage(msg);
		}
	};

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_custom_progress_mypage_color);

		showIndeterDialog();
	}

	private void showIndeterDialog() {
		mCount = 0;

		mColor = (ProgressBar) findViewById(R.id.progress_horizontal_color);
		mColor.setMax(100);
		mColor.setProgress(0);
		//)就是滚动条的当前值自动在最小到最大值之间来回移动，形成这样一个动画效果，这个只是告诉别人“我正在工作”，但不能提示工作进度到哪个阶段
		mColor.setIndeterminate(false);
		new Thread() {
			public void run() {
				try {
					while (mCount <= 100) {
						mColor.setProgress(mCount++);
						Thread.sleep(100);
					}
					if (mCount > 100) {
						mHandler.sendEmptyMessage(HANDLER_LEFT);
					}
				} catch (Exception ex) {
				}
			}
		}.start();
	}
}

看activity_custom_progress_mypage_color.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    android:orientation="vertical" >

    <ProgressBar
        android:id="@+id/progress_horizontal_color"
        style="@style/progressBarHorizontal_color"
        android:layout_width="200dip"
        android:layout_height="10dip"
        android:max="100"
        android:progress="41" />
</LinearLayout>

styles.xml

 <style name="progressBarHorizontal_color" parent="android:Widget.ProgressBar.Horizontal">
        <item name="android:indeterminateOnly">false</item>
        <item name="android:progressDrawable">@drawable/progress_color_horizontal</item>
        <item name="android:minHeight">5dip</item>
        <item name="android:maxHeight">5dip</item>
    </style>

接下来看drawable

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <!--
         最下边层
    	angle表示方向角度，0为从左向又，然后逆时针转，90时候表示从下往上
    -->
    <item android:id="@android:id/background">
        <shape>
            <corners android:radius="5dip" />

            <gradient
                android:angle="90"
                android:centerColor="#ff5a5d5a"
                android:centerY="0.75"
                android:endColor="#ff747674"
                android:startColor="#ff9d9e9d" />
        </shape>
    </item>
    <item android:id="@android:id/progress">
        <clip>
            <shape>
                <corners android:radius="5dip" />

                <gradient
                    android:angle="90"
                    android:centerColor="#ffBBFFBB"
                    android:centerY="0.75"
                    android:endColor="#ff00DB00"
                    android:startColor="#ff00DB00" />
            </shape>
        </clip>
    </item>

</layer-list>

----------------------------------------------第一个效果实现了，下面是同样效果的第二种方法----------------------------------------------------

  <style name="progressBarHorizontal" parent="android:Widget.ProgressBar.Horizontal">
        <item name="android:indeterminateOnly">false</item>
        <item name="android:progressDrawable">@drawable/progress_horizontal</item>
        <item name="android:minHeight">5dip</item>
        <item name="android:maxHeight">5dip</item>
    </style>

接下来看drawable

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@android:id/background"
        android:drawable="@drawable/progressbar_back">
    </item>
    <item
        android:id="@android:id/progress"
        android:drawable="@drawable/progressbar_indeter1">
    </item>

</layer-list>
