大多数中,使用系统内置的dialog并不能满足UE的设计需要
通常我们只需要关注三个回调方法:
自定义布局文件:随便写一个
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/threat_call_rootView" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@drawable/dialog_white_big_corner_roundrect_bg"> <LinearLayout android:id="@+id/threat_call_container" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@drawable/dialog_white_big_corner_roundrect_bg" android:orientation="vertical" android:paddingLeft="32dp" android:paddingTop="48dp" android:paddingRight="32dp" android:paddingBottom="48dp"> <TextView android:id="@+id/threat_call_number" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:text="标题" android:textColor="@color/black" android:textSize="20sp" android:textStyle="bold" /> <TextView android:id="@+id/threat_call_desc" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="4dp" android:lineSpacingExtra="3sp" android:text="正文" android:textColor="@color/black" android:textSize="14sp" /> <EditText android:id="@+id/threat_call_edittext" android:layout_width="match_parent" android:layout_height="48dp" android:layout_marginTop="16dp" android:width="100dp" android:background="@drawable/sip_threat_call_dialog_edittext_stroke"//给editText加个外边框 android:hint=" (optional)" android:lineSpacingExtra="3sp" android:maxLength="255" android:minLines="1" android:paddingLeft="5dp"//这个属性的一个妙用可以改变光标的起始位置,不然光标有可能看不到 android:text="" android:textCursorDrawable="@null" android:textSize="14sp" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" /> <Button android:id="@+id/threat_call_block_btn" android:layout_width="match_parent" android:layout_height="48dp" android:layout_marginTop="16dp" android:background="@drawable/sip_threat_call_dialog_btn_bg" android:gravity="center" android:text="BLOCK" android:textStyle="bold" /> <Button android:id="@+id/threat_call_cancel_btn" android:layout_width="match_parent" android:layout_height="48dp" android:layout_marginTop="1dp" android:background="@drawable/sip_threat_call_dialog_btn_bg" android:gravity="center" android:text="CANCEL" android:textStyle="bold" /> </LinearLayout> </RelativeLayout>
selfFragment类:
package com.example.hellojni; import android.animation.ObjectAnimator; import android.annotation.SuppressLint; import android.app.Dialog; import android.content.Context; import android.content.DialogInterface; import android.graphics.Color; import android.graphics.drawable.ColorDrawable; import android.os.Bundle; import android.view.Gravity; import android.view.LayoutInflater; import android.view.MotionEvent; import android.view.View; import android.view.ViewGroup; import android.view.Window; import android.view.WindowManager; import android.view.inputmethod.InputMethodManager; import android.widget.EditText; import androidx.annotation.NonNull; import androidx.annotation.Nullable; import androidx.fragment.app.DialogFragment; public class selfDialogFragment extends DialogFragment { View container; @NonNull @Override public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) { return new Dialog(getContext(),R.style.bottom_dialog); // return super.onCreateDialog(savedInstanceState);//不采用系统默认的dialog样式,自定义dialog主题 } @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { Window window = getDialog().getWindow(); window.setLayout(WindowManager.LayoutParams.MATCH_PARENT,WindowManager.LayoutParams.WRAP_CONTENT); window.setGravity(Gravity.CENTER);//设置dialog位置处于中央 if(!iPaid(getContext())){ window.getDecorView().setMinimumWidth(getResources().getDisplayMetrics().widthPixels);//这个设置的目的是为了让dialog横向宽度是充满屏幕的 } // window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);//本来想解决dialog打开软键盘后,弹窗跟着往上走的效果,效果确实有,不过依然没有解决我的问题,下面会详解。 return inflater.inflate(R.layout.dialog_block_reason,container,false); } @Override public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); View dialogViewContent = view.findViewById(R.id.block_number_container); EditText editText = view.findViewById(R.id.optional_block_number); container = view.findViewById(R.id.block_number_container); editText.requestFocus(); InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE); dialogViewContent.setOnTouchListener(new View.OnTouchListener() { @SuppressLint("ClickableViewAccessibility") @Override public boolean onTouch(View v, MotionEvent event) { //强制收起软件盘的方式: InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(editText.getWindowToken(),0); return false; } }); view.findViewById(R.id.cancel_btn).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { dismissAllowingStateLoss(); hideSoftInputAndDissmissDialog(); } }); private void hideSoftInputAndDissmissDialog() { dismissAllowingStateLoss(); if (getActivity() != null) {//为了解决dialog弹出软键盘退出界面后软键盘依然存在的问题 getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN); } } @Override public void onStart() { super.onStart(); } //判断是否为Pad的方法,通过计算屏幕对角线长度 private boolean isPad(Context context) { WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE); Display display = wm.getDefaultDisplay(); DisplayMetrics dm = new DisplayMetrics(); display.getMetrics(dm); double x = Math.pow(dm.widthPixels / dm.xdpi, 2); double y = Math.pow(dm.heightPixels / dm.ydpi, 2); double screenInches = Math.sqrt(x + y); // 屏幕尺寸 return screenInches >= 7.0; } }
<item name="android:windowIsFloating">false</item>
指定为false的话,即便加上了 window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
也不行 效果如下:可以清楚的看到,软键盘还是挡住了两个按钮
android:windowIsFloating
设为true时,效果如下:
不过中间多出来的那块我也不知道受什么因素影响的,目前这个样式还能凑活用吧
我这边用了使用了window.getDecorView().setMinimumWidth(getResources().getDisplayMetrics().widthPixels);
生效了,有的博客说是使用 window.getDecorView().setPadding(0,0,0,0)
或者主题中有个属性android:windowFullscree
,不过这两个我试过都貌似都没有什么效果
这个点我使用了getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
解决了,这句话等同于在展示dialog的activity中androidMenifests文件中设置 andorid:windowSoftInputMode = stateAlwaysHidden
,而仅仅设置成stateHidden是不够的,具体这两个参数的详细区别,官方文档说的也很含糊,反正我没读懂。
我比较认同这篇文章的看法: Android 进入Activity时如何禁止弹出软键盘输入法
enter动画:
<?xml version="1.0" encoding="utf-8"?> <translate xmlns:android="http://schemas.android.com/apk/res/android" android:fromYDelta="100%p" android:interpolator="@android:anim/accelerate_decelerate_interpolator" android:toYDelta="50%p" android:duration="200"> </translate>
exit动画:
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" android:shareInterpolator="false" > <scale android:fromXScale="1.0" android:toXScale="0.9" android:fromYScale="1.0" android:toYScale="0.9" android:pivotX="50%" android:pivotY="50%" android:interpolator="@android:anim/decelerate_interpolator" android:duration="150" /> <alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:interpolator="@android:anim/decelerate_interpolator" android:duration="150"/> </set>
通常只需要关注onCreate
方法,在该方法中,一般需要做如下几个事情:
setContentView
将自定义的布局填充到dialog中去在构造函数中设置想要的主题:这里提供两种比较常用的主题
<!--对话框会在屏幕中间显示--> <style name="dialog_theme_center_dispay" parent="@android:style/Theme.Dialog"> <item name="android:windowFrame">@null</item><!-- 设置dialog空白背景--> <item name="android:windowIsFloating">true</item> <!-- dialog是否悬浮,当有软键盘的时候会被顶上去--> <item name="android:windowIsTranslucent">false</item> <!-- dialog是否半透明 --> <item name="android:windowMinWidthMinor">100%</item> <!-- dialog横向宽度充满整个屏幕 --> <item name="android:windowNoTitle">true</item><!-- dialog是否有标题 --> <item name="android:windowBackground">@color/transparent</item><!-- dialog背景是透明的 --> <item name="android:background">@color/transparent</item> <item name="android:backgroundDimEnabled">true</item> <item name="android:windowSoftInputMode">stateHidden|adjustResize</item> </style> <!--对话框会从底部弹出--> <style name="dialog_theme_bottom2top"> <item name="android:windowFrame">@null</item> <item name="android:windowIsFloating">true</item> <item name="android:windowIsTranslucent">false</item> <item name="android:windowNoTitle">true</item> <item name="android:windowBackground">@color/transparent</item> <item name="android:backgroundDimEnabled">true</item> <!--是否允许对话框的背景变暗:如果允许背景就变暗了。--> <item name="android:windowMinWidthMinor">100%</item><!--宽度铺满全屏--> <item name="android:windowCloseOnTouchOutside">true</item><!--点击阴影的地方是否可以关闭对话框--> <item name="android:windowAnimationStyle">@style/dialog_anim_bottom2top</item><!--对话框动画--> <item name="android:windowSoftInputMode">stateHidden|adjustResize</item> </style> <!--[对话框动画]对话框会从底部弹出--> <style name="dialog_anim_bottom2top" parent="@android:style/Animation"> <item name="android:windowEnterAnimation">@anim/bottom_in</item> <item name="android:windowExitAnimation">@anim/bottom_out</item> </style>
bottom_in:
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:duration="300" android:fromYDelta="100%p" android:toYDelta="0" /> </set>
bottom_out:
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:duration="200" android:fromYDelta="0" android:toYDelta="50%p" /> <alpha android:duration="200" android:fromAlpha="1.0" android:toAlpha="0.0" /> </set>
辨别当前设备是否是平板的方法通常有两种:
public static boolean isLargeScreen(Context context) { Configuration config = context.getResources().getConfiguration(); int size = config.screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK; return (size >= Configuration.SCREENLAYOUT_SIZE_LARGE); }
public static boolean isPad(Context context) { WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE); Display display = wm.getDefaultDisplay(); DisplayMetrics dm = new DisplayMetrics(); display.getMetrics(dm); double x = Math.pow(dm.widthPixels / dm.xdpi, 2); double y = Math.pow(dm.heightPixels / dm.ydpi, 2); double screenInches = Math.sqrt(x + y); // 屏幕尺寸 return screenInches >= 7.0; }
