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：

2.列表中的Edittext,利用假键盘实现键盘不遮挡

使用方法：

    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>

        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
            }
        });
    }
}
