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">

android:text="提现"
android:textColor="#ffffff" />

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：
<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
}
});
}
}
