Lance老师UI系列教程第五课->自定义风格单选多选对话框的实现

UI系列教程第五课：自定义单选多选对话框的实现

在Android的应用中，常常会用到单选和多选对话框

最简单的方式是直接使用系统自带的对话框

不过有时候出于对应用程序整体风格的考虑

会用到自定义的对话框

说到自定义对话框，无非就是两种实现方式

一种是自定义dialog，另一种就是popwindow

二者皆是设置自定义布局然后再进行一些属性设置

这里包括对话框本身的设置以及对内部控件的监听设置

本文就以常用的单选多选对话框为例来讲解其实现

先来看效果图：

                                                   

 

                                                   

 

再看工程代码结构：

 

看ACTIVITY里的调用

public class CustomDialogActivity extends Activity implements OnClickListener{private View mRootView;private Button mBtn1;private Button mBtn2;private Button mBtn3;private Button mBtn4;private SingleChoicePopWindow mSingleChoicePopWindow;private MultiChoicePopWindow mMultiChoicePopWindow;private SingleChoiceDialog mSingleChoiceDialog;private MultiChoicDialog mMultiChoicDialog;private List<String> mSingleDataList;private List<String> mMultiDataList;private Context mContext;    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                mContext = this;                initView();                initData();    }        public void initView()    {    mBtn1 = (Button) findViewById(R.id.button1);    mBtn1.setOnClickListener(this);        mBtn2 = (Button) findViewById(R.id.button2);    mBtn2.setOnClickListener(this);        mBtn3 = (Button) findViewById(R.id.button3);    mBtn3.setOnClickListener(this);        mBtn4 = (Button) findViewById(R.id.button4);    mBtn4.setOnClickListener(this);            mRootView = findViewById(R.id.rootView);    }        private final static int COUNT = 3;        public void initData()    {    mSingleDataList = new ArrayList<String>();    mMultiDataList = new ArrayList<String>();    boolean booleans[] = new boolean[COUNT * 5];        for(int i = 0; i < COUNT; i++)    {    String string1 = "geniuseoe2012 -->" + i;    mSingleDataList.add(string1);    }        for(int i = 0; i < COUNT * 2; i++)    {    String string2 = "talent -->" + i;    mMultiDataList.add(string2);    }        initPopWindow(booleans);        initDialog(booleans);     }            public void initPopWindow(boolean []booleans)    {    mSingleChoicePopWindow = new SingleChoicePopWindow(this, mRootView, mSingleDataList);        mSingleChoicePopWindow.setTitle("genius single title");    mSingleChoicePopWindow.setOnOKButtonListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubint selItem = mSingleChoicePopWindow.getSelectItem();Toast.makeText(mContext, "selItem = " + selItem, Toast.LENGTH_SHORT).show();}});        mMultiChoicePopWindow = new MultiChoicePopWindow(this, mRootView, mMultiDataList, booleans);       mMultiChoicePopWindow.setTitle("genius multi title");    mMultiChoicePopWindow.setOnOKButtonListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubboolean []selItems = mMultiChoicePopWindow.getSelectItem();int size = selItems.length;StringBuffer stringBuffer = new StringBuffer();for(int i = 0; i < size; i++){if (selItems[i]){stringBuffer.append(i + " ");}}Toast.makeText(mContext, "selItems = " + stringBuffer.toString(), Toast.LENGTH_SHORT).show();}});    }        public void initDialog(boolean []booleans)    {    mSingleChoiceDialog = new SingleChoiceDialog(this, mSingleDataList);    mSingleChoiceDialog.setTitle("genius single title");    mSingleChoiceDialog.setOnOKButtonListener(new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stubint selItem = mSingleChoiceDialog.getSelectItem();Toast.makeText(mContext, "selItem = " + selItem, Toast.LENGTH_SHORT).show();}});                mMultiChoicDialog = new MultiChoicDialog(this, mMultiDataList, booleans);    mMultiChoicDialog.setTitle("genius multi title");    mMultiChoicDialog.setOnOKButtonListener(new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stubboolean []selItems = mMultiChoicDialog.getSelectItem();int size = selItems.length;StringBuffer stringBuffer = new StringBuffer();for(int i = 0; i < size; i++){if (selItems[i]){stringBuffer.append(i + " ");}}Toast.makeText(mContext, "selItems = " + stringBuffer.toString(), Toast.LENGTH_SHORT).show();}});       }        @Overridepublic void onClick(View v) {// TODO Auto-generated method stubswitch(v.getId()){case R.id.button1:showSingleChoiceWindow();break;case R.id.button2:showMultiChoiceWindow();break;case R.id.button3:showSingleChoiceDialog();break;case R.id.button4:showMultiChoiceDialog();break;}}public void showSingleChoiceWindow(){mSingleChoicePopWindow.show(true);}public void showMultiChoiceWindow(){mMultiChoicePopWindow.show(true);}public void showSingleChoiceDialog(){mSingleChoiceDialog.show();}public void showMultiChoiceDialog(){mMultiChoicDialog.show();}}

以单选popwindow为例，其调用方式如下：

mSingleChoicePopWindow = new SingleChoicePopWindow(this, mRootView, mSingleDataList);        mSingleChoicePopWindow.setTitle("genius single title");    mSingleChoicePopWindow.setOnOKButtonListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubint selItem = mSingleChoicePopWindow.getSelectItem();Toast.makeText(mContext, "selItem = " + selItem, Toast.LENGTH_SHORT).show();}});

1.初始化对象

2.设置标题

3.添加按钮监听

最后在监听回调里通过getSelectItem方法获取选择值即可得到结果值，简洁易用

大家可直接拷贝到项目里再根据具体情况做细微调整即可

不过不知道为什么dialog始终无法填充全屏，所以只好去掉布局的背景色好与周围的暗色融为一体
