鸿蒙 dialog
首先创建一个BaseDialog
public class BaseDialog extends CommonDialog { /** * 类似Android Dialog的cancelable属性， * true: 支持点击外部或返回键消失。 * false: 则只有手动调用hide才会消失。 */ private boolean cancelable = true; protected boolean hideWithBackPressed; private OnShowListener onShowListener; private OnDismissListener onHideListener; public BaseDialog(Context context) { super(context); } public boolean isCancelable() { return cancelable; } public void setCancelable(boolean cancelable) { this.cancelable = cancelable; if (!cancelable) { setAutoClosable(false); } } @Override public boolean clickKeyDown(KeyEvent event) { if (event.getKeyCode() == KeyEvent.KEY_BACK) { if (cancelable) { if (isShowing()) { hideWithBackPressed = true; destroy(); return true; } } else { return true; } } return super.clickKeyDown(event); } @Override protected void onShow() { super.onShow(); hideWithBackPressed = false; if (onShowListener != null) { onShowListener.onShow(this); } } @Override protected void onShowing() { super.onShowing(); } @Override protected void onHide() { super.onHide(); } @Override protected void onDestroy() { super.onDestroy(); if (onHideListener != null) { onHideListener.onDismiss(this, hideWithBackPressed); } } public void setOnShowListener(OnShowListener onShowListener) { this.onShowListener = onShowListener; } public void setOnDismissListener(OnDismissListener onHideListener) { this.onHideListener = onHideListener; } public interface OnShowListener { void onShow(IDialog dialog); } public interface OnDismissListener { void onDismiss(IDialog dialog, boolean withBackPressed); } }

使用方法
类型1关注类型
String content = "我是一个菜鸟工程师哦！"; DialogUtils dialog = new DialogUtils.Builder(MainAbilitySlice.this) .setCancelable(true) .setRightButtonTitle("取消") .setLeftButtonTitle("确定") .setTitleContent(content) .setListener(new DialogUtils.Builder.DialogListener() { @Override public void ok() { //删除微博 } @Override public void cancel() { } }) .build(); dialog.show();

效果

WeiboDialog dialogUtils = new WeiboDialog.Builder(MainAbilitySlice.this) .setListener(new WeiboDialog.Builder.DialogListener() { @Override public void ok() { } @Override public void cancel() { } }) .setmType(1) .setTitle("应用想访问您的照片") .isbuttoncolor(true) .setTitleContent("如果不允许您将无法保存到相册,也无法分享到本软件") .setLeftButtonColor("#0066CC") .setRightButtonColor("#0066CC") .isBtnType(1) .setRightButtonTitle("不允许") .setLeftButtonTitle("好") .build(); dialogUtils.show();

还有其他类型根据需求自己定义
提供一个text工具
public class TextUtils { public static boolean isEmpty(CharSequence str) { return str == null || str.length() == 0; } public static boolean equals(CharSequence a, CharSequence b) { if (a == b) return true; int length; if (a != null && b != null && (length = a.length()) == b.length()) { if (a instanceof String && b instanceof String) { return a.equals(b); } else { for (int i = 0; i < length; i++) { if (a.charAt(i) != b.charAt(i)) return false; } return true; } } return false; } public static String toString(String value){ if(isEmpty(value)){ return ""; } if(isEmpty(value.trim())){ return ""; } return value; } /** * Returns whether the given CharSequence contains only digits. */ public static boolean isDigitsOnly(CharSequence str) { final int len = str.length(); for (int cp, i = 0; i < len; i += Character.charCount(cp)) { cp = Character.codePointAt(str, i); if (!Character.isDigit(cp)) { return false; } } return true; } public static int measureText(Paint p, String text) { if (p == null || text == null) return 0; float[] charWidth = new float[text.length()]; p.getAdvanceWidths(text, charWidth); float totalWidth = 0; for(float w : charWidth) { totalWidth += w; } return (int) totalWidth; } public static boolean endsWith(String str, String end) { return !isEmpty(str) && str.endsWith(end); } }
