Android几行代码解决键盘遮挡问题

GitHub

APK

将libray模块复制到项目中,或者直接在build.gradle中依赖:

allprojects { repositories { maven { url 'https://jitpack.io' } } }

dependencies { compile 'com.github.AnJiaoDe:Keyboard:V1.0.0' }

注意：如果sync报错，是因为和com.android.tools.build:gradle 3.0有关，
可以改将compile改为implementation 或者api

1.scrollTo、scrollBy实现键盘不遮挡

使用方法：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <RelativeLayout android:layout_width="match_parent" android:layout_height="44dp" android:background="@color/colorPrimary"> <TextView android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:text="提现" android:textColor="#ffffff" /> </RelativeLayout> <LinearLayout android:id="@+id/layout_content" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#E9F4FB" android:orientation="vertical"> <LinearLayout android:layout_width="match_parent" android:layout_height="38dp" android:layout_marginLeft="15dp" android:layout_marginRight="15dp" android:gravity="center_vertical" android:orientation="horizontal"> <View android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" /> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" android:orientation="vertical"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="15dp" android:orientation="horizontal"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="可提余额：" android:textColor="#333333" android:textSize="15sp" /> <TextView android:id="@+id/tv_yue" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="2000.00" android:textColor="#666666" android:textSize="14sp" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="元" android:textColor="#333333" android:textSize="14sp" /> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="15dp" android:layout_marginTop="20dp" android:orientation="horizontal"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="手续费(0.6%):" android:textColor="#333333" android:textSize="15sp" /> <TextView android:id="@+id/tv_shouxufei" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="0.00" android:textColor="#666666" android:textSize="14sp" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="元" android:textColor="#333333" android:textSize="14sp" /> </LinearLayout> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="15dp" android:layout_marginTop="20dp" android:gravity="center_vertical" android:orientation="horizontal"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="提现方式:" android:textColor="#333333" android:textSize="15sp" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="3dp" android:text="支付宝" android:textColor="#666666" android:textSize="14sp" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="3dp" android:text="银行卡" android:textColor="#666666" android:textSize="14sp" /> </LinearLayout> <View android:layout_width="match_parent" android:layout_height="1dp" android:layout_marginTop="20dp" android:background="@color/line" /> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="11dp" android:gravity="center" android:text="申请提现金额" android:textColor="#333333" android:textSize="15sp" /> <LinearLayout android:id="@+id/layout_et" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="23dp" android:layout_marginRight="23dp" android:layout_marginTop="13dp" android:orientation="vertical"> <View android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1"/> <EditText android:id="@+id/et_jine" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="30dp" android:background="@null" android:gravity="center" android:hint="请输入提现金额" android:inputType="numberDecimal|number" android:maxLength="20" android:minHeight="44dp" android:textColorHint="#999999" android:textSize="14sp" /> <View android:layout_width="match_parent" android:layout_height="1dp" android:layout_marginTop="30dp" android:background="#A7ABB1" /> </LinearLayout> <Button android:id="@+id/tv_submit" android:layout_width="match_parent" android:layout_height="49dp" android:layout_marginLeft="38dp" android:layout_marginRight="38dp" android:layout_marginTop="33dp" android:gravity="center" android:text="确定" android:textColor="@color/white" android:textSize="16sp" /> </LinearLayout> </LinearLayout> </LinearLayout> 

public class EditTextActivity extends KeyboardActivity { private View layout_content; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_edit_text); layout_content=findViewById(R.id.layout_content); //设置监听器 setOnCYGlobalLayoutListener(new OnCYGlobalLayoutListener() { //键盘刚显示 @Override public void onKeyboardShowedNow(Rect rect) { //rect 可视区域 //screenHight-rect.bottom就是键盘高度 layout_content.scrollTo(0,screenHight-rect.bottom); } //键盘刚隐藏,可以对输入的内容进行修改 @Override public void onKeyboardHideNow() { layout_content.scrollTo(0,0); } }); } }

2.列表中的Edittext,利用假键盘实现键盘不遮挡

使用方法：

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_modify_price2" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <RelativeLayout android:background="@color/colorPrimary" android:layout_width="match_parent" android:layout_height="44dp"> <TextView android:layout_width="match_parent" android:gravity="center" android:layout_height="match_parent" android:text="修改价格" android:textColor="#ffffff" /> </RelativeLayout> <com.cy.cyrvadapter.recyclerview.VerticalRecyclerView android:id="@+id/vrv" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" /> <View android:id="@+id/view_keyboard" android:layout_width="match_parent" android:layout_height="0dp" /> </LinearLayout> 

public class RVEdittextActivity extends KeyboardMockActivity { private RVAdapter<String> rvAdapter; private View view_keybord; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_rvedittext); List<String> list = new ArrayList<>(); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); list.add("dojij"); rvAdapter = new RVAdapter<String>(list) { @Override public void bindDataToView(RVViewHolder holder, int position, String bean, boolean isSelected) { } @Override public int getItemLayoutID(int position, String bean) { return R.layout.item_price_modify; } @Override public void onItemClick(int position, String bean) { } }; //万能适配器：https://github.com/AnJiaoDe/RecyclerViewAdapter ((VerticalRecyclerView) findViewById(R.id.vrv)).setAdapter(rvAdapter); //设置监听器 setOnCYGlobalLayoutListener(view_keybord, new OnCYGlobalLayoutListener() { //键盘刚显示 @Override public void onKeyboardShowedNow(Rect rect) { } //键盘刚隐藏,可以对输入的内容进行修改 @Override public void onKeyboardHideNow() { } //假键盘高度 @Override public int getViewKeyboardHeight(Rect rect) { return screenHight-rect.bottom;//screenHight-rect.bottom就是键盘高度 } }); } }
