Android 自訂主菜單

Android 自訂主菜單

本文介紹一個超簡單的自訂主菜單，效果如下：

原理：其實就是對原生的Dialog的一個簡單的封裝。並加上顯示和隱藏的動畫效果。再給控制項加上回調事件。

 

TestDialog.java

 

public class TestDialog implements OnClickListener {private Context mContext;private Dialog mDialog;private Display mDisplay;private TextView mTitle;private TextView mOk, mCancel;private LinearLayout mContent;private List mItems = null;private List mListeners = null;private List mDrawables = null;public TestDialog(Context context) {this.mContext = context;WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);mDisplay = windowManager.getDefaultDisplay();}/** * builder()建立 *  * @return */public TestDialog builder(int layout) {initView(layout);return this;}/** * 初始化Dialog視圖的方法 *  * @param layout */private void initView(int layout) {View view = LayoutInflater.from(mContext).inflate(layout, null);view.setMinimumWidth(mDisplay.getWidth());//mTitle = (TextView) view.findViewById(R.id.menu_title);mContent = (LinearLayout) view.findViewById(R.id.menu_content);mOk = (TextView) view.findViewById(R.id.menu_ok);mCancel = (TextView) view.findViewById(R.id.menu_cancel);mOk.setOnClickListener(this);mCancel.setOnClickListener(this);mDialog = new Dialog(mContext, R.style.DialogStyle);mDialog.setContentView(view);Window dialogWindow = mDialog.getWindow();dialogWindow.setGravity(Gravity.LEFT | Gravity.BOTTOM);WindowManager.LayoutParams lp = dialogWindow.getAttributes();lp.x = 0;lp.y = 0;dialogWindow.setAttributes(lp);}/** *  * @param 是否能取消 * @return */public TestDialog setCancelable(boolean b) {if (mDialog != null) {mDialog.setCancelable(b);}return this;}/** * 設定對話方塊標題 *  * @param title * @return */public TestDialog setTitle(String title) {if (mDialog != null) {mTitle.setText(title);mTitle.setVisibility(View.VISIBLE);}return this;}/** *  * @param 點擊Dialog以外的部分是否可以取消 * @return */public TestDialog set(boolean b) {if (mDialog != null) {mDialog.setCanceledOnTouchOutside(b);}return this;}/** * 取消 */public void dismiss() {mDialog.dismiss();}/** * 用來裝視圖資料的集合 *  * @param title * @return */public TestDialog addItem(String title, Drawable drawable, OnCustomItemClickListener clickListener) {if (mItems == null) {mItems = new ArrayList();}if (mListeners == null) {mListeners = new ArrayList();}if (mDrawables == null) {mDrawables = new ArrayList();}mItems.add(title);mListeners.add(clickListener);mDrawables.add(drawable);return this;}private void setItem() {if (mItems == null || mItems.size() <= 0) {return;}int count = mItems.size();for (int i = 0; i < count; i++) {final int index = i;TextView view = new TextView(mContext);view.setText(object + 1);view.setCompoundDrawablesRelativeWithIntrinsicBounds(null, mDrawables.get(i), null, null);view.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubmListeners.get(index).onClick(index);}});mContent.addView(view);}}public void show() {setItem();mDialog.show();}public interface OnCustomItemClickListener {public abstract void onClick(int v);}@Overridepublic void onClick(View v) {if (v == mOk) {} else if (v == mCancel) {}mDialog.dismiss();}}
