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：

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 rvAdapter;    private View view_keybord;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_rvedittext);        List 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(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            }        });    }}
