        前段时间客户需求,要加几个按钮,包括清理缓存,关于,设置,定位等。可是界面已经做好了,再重新布局界面,很麻烦。所以做了这么个小Button。在此分享,供大家学习。下面是几张截图,动画效果没工具保存,是依次展开的。文末附有源码下载链接。

首先上自定义布局文件:ComposerLayout.java

package com.example.button;

import android.annotation.SuppressLint;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.util.AttributeSet;
import android.view.View;

import android.widget.RelativeLayout;

@SuppressLint("ViewConstructor")
public class ComposerLayout extends RelativeLayout {

	public static byte RIGHTBOTTOM = 1, CENTERBOTTOM = 2, LEFTBOTTOM = 3,
			LEFTCENTER = 4, LEFTTOP = 5, CENTERTOP = 6, RIGHTTOP = 7,
			RIGHTCENTER = 8;
	private boolean hasInit = false; 
	private boolean areButtonsShowing = false;
	private Context mycontext;
	private ImageView cross; 
	private RelativeLayout rlButton;
	private Animations myani; 
	private LinearLayout[] llayouts; 
	private int duretime = 300;


	public ComposerLayout(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
		this.mycontext = context;
	}

	public ComposerLayout(Context context, AttributeSet attrs) {
		super(context, attrs);
		this.mycontext = context;
	}

	public ComposerLayout(Context context) {
		super(context);
		this.mycontext = context;
	}

	/**

	public void init(int[] imgResId, int showhideButtonId, int crossId,
			byte pCode, int radius, final int durationMillis) {
		duretime = durationMillis;
		int align1 = 12, align2 = 14;

				thislps.height = (int) (radius * 1.1 + mBottom.getHeight());
			}
		}
		this.setLayoutParams(thislps);
		RelativeLayout rl1 = new RelativeLayout(mycontext);// 包含若干子按鈕

		rlButton = new RelativeLayout(mycontext); // 主按扭
		llayouts = new LinearLayout[imgResId.length];
		// N个子按鈕
		for (int i = 0; i < imgResId.length; i++) {

			RelativeLayout.LayoutParams rlps = new RelativeLayout.LayoutParams(
					RelativeLayout.LayoutParams.WRAP_CONTENT,
					RelativeLayout.LayoutParams.WRAP_CONTENT);
			rlps.alignWithParent = true;
			rlps.addRule(align1, RelativeLayout.TRUE);
			rlps.addRule(align2, RelativeLayout.TRUE);
			llayouts[i].setLayoutParams(rlps);
			llayouts[i].setVisibility(View.INVISIBLE);// 此处不能为GONE
			rl1.addView(llayouts[i]);
		}
		RelativeLayout.LayoutParams rlps1 = new RelativeLayout.LayoutParams(
				RelativeLayout.LayoutParams.FILL_PARENT,
				RelativeLayout.LayoutParams.FILL_PARENT);
		rlps1.alignWithParent = true;
		rlps1.addRule(align1, RelativeLayout.TRUE);
		rlps1.addRule(align2, RelativeLayout.TRUE);
		rl1.setLayoutParams(rlps1);

		RelativeLayout.LayoutParams buttonlps = new RelativeLayout.LayoutParams(
				RelativeLayout.LayoutParams.WRAP_CONTENT,
				RelativeLayout.LayoutParams.WRAP_CONTENT);
		buttonlps.alignWithParent = true;
		buttonlps.addRule(align1, RelativeLayout.TRUE);
		buttonlps.addRule(align2, RelativeLayout.TRUE);

		cross.setLayoutParams(crosslps);
		rlButton.addView(cross);
		myani = new Animations(rl1, pCode, radius);
		rlButton.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				if (areButtonsShowing) {
					myani.startAnimationsOut(duretime);
					cross.startAnimation(Animations.getRotateAnimation(-270,
							0, duretime));
				} else {
					myani.startAnimationsIn(duretime);
					cross.startAnimation(Animations.getRotateAnimation(0,
							-270, duretime));
				}
				areButtonsShowing = !areButtonsShowing;
			}
		});

		cross.startAnimation(Animations.getRotateAnimation(0, 360, 200));
		this.addView(rl1);
		this.addView(rlButton);
		hasInit = true;

	}

	public void collapse() {
		myani.startAnimationsOut(duretime);
		cross.startAnimation(Animations.getRotateAnimation(-270, 0, duretime));
		areButtonsShowing = false;
	}


	public void expand() {
		myani.startAnimationsIn(duretime);
		cross.startAnimation(Animations.getRotateAnimation(0, -270, duretime));
		areButtonsShowing = true;
	}

	public boolean isInit() {
		return hasInit;
	}

	public boolean isShow() {
		return areButtonsShowing;
	}

	/**
	 * 设置各子按钮OnClick事件
	 */
	public void setButtonsOnClickListener(final OnClickListener l) {

		if (llayouts != null) {
			for (int i = 0; i < llayouts.length; i++) {
				if (llayouts[i] != null)
					llayouts[i].setOnClickListener(new OnClickListener() {

						@Override
						public void onClick(final View view) {
							//此处添加其他事件比如按钮增大或者缩回菜单
							collapse();
							l.onClick(view);
						}

					});
			}
		}
	}
}
这里自定义了一个BaseActivity,使用BaseActivity的好处不用我说了吧:

package com.example.button;


import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;

public abstract class BaseActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setView();
		initView();
		setListener();
		initData();
	}
	
	@Override
	protected void onResume() {
		super.onResume();
	}
	
	@Override
	protected void onPause() {
		super.onPause();
	}

	/**
	 * 设置布局文件
	 */
	public abstract void setView();

	/**
	 * 初始化布局文件中的控件
	 */
	public abstract void initView();

	/**
	 * 设置控件的监听
	 */
	public abstract void setListener();
	
	private void initData() {
		String appID = "wx88818f8c48a95eb4";
	}
	@Override 
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
	    super.onActivityResult(requestCode, resultCode, data);
	}
	
	
	
	
	
}
动画设置类,Animations,这里用了一个开源动画库nineoldandroids.jar。下载文末原代码中有

package com.example.button;

import static com.nineoldandroids.view.ViewPropertyAnimator.animate;

public class Animations {
	public final int R; // 半径
	public static byte RIGHTBOTTOM = 1, CENTERBOTTOM = 2, LEFTBOTTOM = 3,
			LEFTCENTER = 4, LEFTTOP = 5, CENTERTOP = 6, RIGHTTOP = 7,
			RIGHTCENTER = 8;

	private int pc; // 位置代号
	private ViewGroup clayout; // 父layout
	private final int amount; // 有幾多個按鈕
	private double fullangle = 180.0;// 在幾大嘅角度內排佈
	private byte xOri = 1, yOri = 1; // x、y值嘅方向,即系向上還是向下
	private boolean isOpen = false;// 记录是已经打开还是关闭
	private List<ViewPropertyAnimator> viewAnimators = new ArrayList<ViewPropertyAnimator>();

	/**
	 * 構造函數
	 * 
	 * @param comlayout
	 *            包裹彈出按鈕嘅layout
	 * @param poscode
	 *            位置代號,分別對應RIGHTBOTTOM、CENTERBOTTOM、LEFTBOTTOM、LEFTCENTER、
	 *            LEFTTOP、CENTERTOP、RIGHTTOP、RIGHTCENTER
	 * @param radius
	 *            半徑
	 */
	public Animations(ViewGroup comlayout, int poscode, int radius) {
		this.pc = poscode;
		this.clayout = comlayout;
		this.amount = clayout.getChildCount();
		this.R = radius;

		// 初始化动画,每个view对应一个animator
		for (int i = 0; i < amount; i++) {
			View childAt = clayout.getChildAt(i);
			ViewPropertyAnimator anim = animate(childAt);
			viewAnimators.add(anim);
		}

		if (poscode == RIGHTBOTTOM) { // 右下角
			fullangle = 90;
			xOri = -1;
			yOri = -1;
		} else if (poscode == CENTERBOTTOM) {// 中下
			fullangle = 180;
			xOri = -1;
			yOri = -1;
		} else if (poscode == LEFTBOTTOM) { // 左下角
			fullangle = 90;
			xOri = 1;
			yOri = -1;
		} else if (poscode == LEFTCENTER) { // 左中
			fullangle = 180;
			xOri = 1;
			yOri = -1;
		} else if (poscode == LEFTTOP) { // 左上角
			fullangle = 90;
			xOri = 1;
			yOri = 1;
		} else if (poscode == CENTERTOP) { // 中上
			fullangle = 180;
			xOri = -1;
			yOri = 1;
		} else if (poscode == RIGHTTOP) { // 右上角
			fullangle = 90;
			xOri = -1;
			yOri = 1;
		} else if (poscode == RIGHTCENTER) { // 右中
			fullangle = 180;
			xOri = -1;
			yOri = -1;
		}
	}

	private class AnimListener implements AnimatorListener {

		private View target;

		public AnimListener(View _target) {
			target = _target;
		}

		@Override
		public void onAnimationStart(Animator animation) {

		}

		@Override
		public void onAnimationEnd(Animator animation) {
			if (!isOpen) {
				target.setVisibility(View.INVISIBLE);
			}
		}

		@Override
		public void onAnimationCancel(Animator animation) {
			// TODO Auto-generated method stub

		}

		@Override
		public void onAnimationRepeat(Animator animation) {
			// TODO Auto-generated method stub

		}
	}

<pre name="code" class="java">        /**

主Activity:TestActivity

package com.example.button;


import android.view.View;
import android.view.View.OnClickListener;
import android.widget.RelativeLayout;
import android.widget.Toast;

public class TestActivity extends BaseActivity {

	private ComposerLayout clayout;
	@Override
	public void setView() {
		setContentView(R.layout.activity_main);
		
	}

	@Override
	public void initView() {
		// 引用控件
		clayout = (ComposerLayout) findViewById(R.id.test);
		clayout.init(new int[] { R.drawable.composer_camera,
				R.drawable.composer_music, R.drawable.composer_place,
				R.drawable.composer_sleep, R.drawable.composer_thought,
				R.drawable.composer_with }, R.drawable.composer_button,
				R.drawable.composer_icn_plus, ComposerLayout.RIGHTCENTER, 180,
				300);
		
	}

	@Override
	public void setListener() {
		// 点击事件监听,100+0对应composer_camera,100+1对应composer_music……如此类推你有机个按钮就加几个按钮都行。
				OnClickListener clickit = new OnClickListener() {
					@Override
					public void onClick(View v) {
						if (v.getId() == 100 + 0) {
							Toast.makeText(TestActivity.this, "测试A", 0).show();
						} else if (v.getId() == 100 + 1) {
							Toast.makeText(TestActivity.this, "测试B...", 0).show();
						} else if (v.getId() == 100 + 2) {
							Toast.makeText(TestActivity.this, "测试C...", 0).show();
						} else if (v.getId() == 100 + 3) {
							Toast.makeText(TestActivity.this, "测试D...", 0).show();
						} else if (v.getId() == 100 + 4) {
							Toast.makeText(TestActivity.this, "测试E...", 0).show();
						} else if (v.getId() == 100 + 5) {
							Toast.makeText(TestActivity.this, "测试F..", 0).show();
						}
					}
				};
				clayout.setButtonsOnClickListener(clickit);

				
				RelativeLayout rl = (RelativeLayout) findViewById(R.id.rlparent);
				rl.setOnClickListener(new OnClickListener() {
					@Override
					public void onClick(View v) {
						// TODO Auto-generated method stub
						Toast.makeText(TestActivity.this, "父控件可以点击的哦!!!", 0).show();
						System.out.println("父控件可以点击。");
					}
				});
		
	}
	
}


接下来是布局文件activity_main:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rlparent"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#ABCDEF" >

    <com.example.button.ComposerLayout
        android:id="@+id/test"
        android:layout_width="20dp"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true" >
    </com.example.button.ComposerLayout>

</RelativeLayout>
