將libray模組複製到專案中,或者直接在build.gradle中依賴:

allprojects {
repositories {

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

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

}

注意：如果sync報錯，是因為和com.android.tools.build:gradle 3.0有關，

可以改將compile改為implementation 或者api

1.scrollTo、scrollBy實現鍵盤不遮擋

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);
//設定監聽器
setOnCYGlobalLayoutListener(new OnCYGlobalLayoutListener() {
//鍵盤剛顯示
@Override
public void onKeyboardShowedNow(Rect rect) {
//rect 可視區域
//screenHight-rect.bottom就是鍵盤高度
layout_content.scrollTo(0,screenHight-rect.bottom);

}
//鍵盤剛隱藏,可以對輸入的內容進行修改


@Override
public void onKeyboardHideNow() {
layout_content.scrollTo(0,0);


}
});
}
}

2.列表中的Edittext,利用假鍵盤實現鍵盤不遮擋

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="修改價格"
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");
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) {

}
};
//萬能介面卡：https://github.com/AnJiaoDe/RecyclerViewAdapter
((VerticalRecyclerView) findViewById(R.id.vrv)).setAdapter(rvAdapter);
//設定監聽器
setOnCYGlobalLayoutListener(view_keybord, new OnCYGlobalLayoutListener() {
//鍵盤剛顯示
@Override
public void onKeyboardShowedNow(Rect rect) {

}

//鍵盤剛隱藏,可以對輸入的內容進行修改
@Override
public void onKeyboardHideNow() {


}

//假鍵盤高度
@Override
public int getViewKeyboardHeight(Rect rect) {
return screenHight-rect.bottom;//screenHight-rect.bottom就是鍵盤高度
}
});
}
}
