作者：吻中求胜
这篇文章主要介绍了Android优雅的方式解决软键盘遮挡按钮问题,非常不错，具有参考借鉴价值，需要的朋友可以参考下
前言
比如在进行登录的操作中，用户输入完密码之后，肯定是想直接点击登录按钮的。返回键隐藏软键盘这样的体验肯定很糟糕，程序员，遇到问题解决问题。
实现1
xml
<ScrollView android:id="@+id/scrollview" android:layout_width="match_parent" android:layout_height="wrap_content" android:fadingEdge="none" android:scrollbars="none"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <ImageView android:layout_width="100dp" android:layout_height="100dp" android:layout_gravity="center_horizontal" android:layout_marginTop="20dp" android:src="@mipmap/ic_loginhead"/> <EditText android:id="@+id/et_usernamelogin_username" style="@style/customEditText" android:layout_width="match_parent" android:layout_height="40dp" android:layout_marginTop="10dp" android:background="@null" android:hint="请输入已验证手机" android:inputType="number" android:lines="1" android:maxLength="11"/> <ImageView android:layout_width="match_parent" android:layout_height="2px" android:layout_marginLeft="50dp" android:layout_marginRight="50dp" android:background="@color/pating_line"/> <EditText android:id="@+id/et_usernamelogin_password" style="@style/customEditText" android:layout_width="match_parent" android:layout_height="40dp" android:layout_marginTop="20dp" android:background="@null" android:digits="0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_?" android:hint="请输入密码" android:inputType="textPassword"/> <ImageView android:layout_width="match_parent" android:layout_height="2px" android:layout_marginLeft="50dp" android:layout_marginRight="50dp" android:background="@color/pating_line"/> <Button android:id="@+id/btn_usernamelogin_dologin" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginLeft="50dp" android:layout_marginRight="50dp" android:layout_marginTop="30dp" android:background="@drawable/btn_selecter" android:enabled="false" android:text="登录" android:textColor="@color/white" /> </LinearLayout> </ScrollView>
java
mScrollView=(ScrollView)view.findViewById(R.id.scrollview);
usernamelogin_username.setOnTouchListener(newView.OnTouchListener(){
@Override
publicbooleanonTouch(Viewv,MotionEventevent){
changeScrollView();
returnfalse;
}
});
usernamelogin_password.setOnTouchListener(newView.OnTouchListener(){
@Override
publicbooleanonTouch(Viewv,MotionEventevent){
changeScrollView();
returnfalse;
}
});
/**
*使ScrollView指向底部
*/
privatevoidchangeScrollView(){
newHandler().postDelayed(newRunnable(){
@Override
publicvoidrun(){
mScrollView.scrollTo(0,mScrollView.getHeight());
}
},300);
}
实现2
xml同上
anim下新建gone.xml
<?xml version="1.0" encoding="utf-8"?> <scale xmlns:android="http://schemas.android.com/apk/res/android" android:fromXScale="1.0" android:toXScale="0.0" android:fromYScale="1.0" android:toYScale="0.0" android:pivotX="50%" android:pivotY="50%" android:duration="500" android:repeatCount="0"/>
visiable.xml
<?xml version="1.0" encoding="utf-8"?> <scale xmlns:android="http://schemas.android.com/apk/res/android" android:fromXScale="0.0" android:toXScale="1.0" android:fromYScale="0.0" android:toYScale="1.0" android:pivotX="50%" android:pivotY="50%" android:duration="500" android:repeatCount="0"/>
或者直接在代码中
importandroid.os.Bundle;
importandroid.os.Handler;
importandroid.support.v7.app.AppCompatActivity;
importandroid.view.KeyEvent;
importandroid.view.MotionEvent;
importandroid.view.View;
importandroid.view.animation.Animation;
importandroid.view.animation.AnimationSet;
importandroid.view.animation.ScaleAnimation;
importandroid.widget.Button;
importandroid.widget.EditText;
importandroid.widget.ImageView;
publicclassMainActivityextendsAppCompatActivity{
privateImageViewmHead;//头部ImageView
@Override
protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mHead=(ImageView)findViewById(R.id.iv_head);
finalButtonbtn=(Button)findViewById(R.id.btn_usernamelogin_dologin);
finalEditTextet_pass=(EditText)findViewById(R.id.et_usernamelogin_password);
finalEditTextet_name=(EditText)findViewById(R.id.et_usernamelogin_username);
/**
*当输入被点击
*/
et_name.setOnTouchListener(newView.OnTouchListener(){
@Override
publicbooleanonTouch(Viewv,MotionEventevent){
start();
returnfalse;
}
});
btn.setEnabled(false);
btn.setOnClickListener(newView.OnClickListener(){
@Override
publicvoidonClick(Viewv){
}
});
}
privatevoidstart(){
AnimationSetanimationSet=newAnimationSet(true);
ScaleAnimationscaleAnimation=newScaleAnimation(
1,0.1f,1,0.1f,
Animation.RELATIVE_TO_SELF,0.5f,
Animation.RELATIVE_TO_SELF,0.5f);
scaleAnimation.setDuration(500);
animationSet.addAnimation(scaleAnimation);
animationSet.setFillAfter(true);
animationSet.setFillBefore(false);
animationSet.setRepeatCount(0);//设置重复次数
mHead.startAnimation(scaleAnimation);
newHandler().postDelayed(newRunnable(){
@Override
publicvoidrun(){
mHead.setVisibility(View.GONE);
}
},500);
}
/**
*菜单、返回键响应
*/
@Override
publicbooleanonKeyDown(intkeyCode,KeyEventevent){
//TODOAuto-generatedmethodstub
if(keyCode==KeyEvent.KEYCODE_BACK){
if(mHead.getVisibility()==View.GONE){
AnimationSetanimationSet=newAnimationSet(true);
ScaleAnimationscaleAnimation=newScaleAnimation(
0.1f,1f,0.1f,1f,
Animation.RELATIVE_TO_SELF,0.5f,
Animation.RELATIVE_TO_SELF,0.5f);
scaleAnimation.setDuration(500);
animationSet.addAnimation(scaleAnimation);
animationSet.setFillAfter(true);
animationSet.setFillBefore(false);
mHead.startAnimation(scaleAnimation);
mHead.setVisibility(View.VISIBLE);
}else{
finish();
}
}
returnfalse;
}
}
效果呢：
