Android应用中出现软键盘遮挡住按钮如何解决？相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。
如图：
实现1
xml
android:id="@+id/scrollview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fadingEdge="none"
android:scrollbars="none">
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_gravity="center_horizontal"
android:layout_marginTop="20dp"
android:src="@mipmap/ic_loginhead"/>
android:id="@+id/et_usernamelogin_username"
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"/>
android:layout_width="match_parent"
android:layout_height="2px"
android:layout_marginLeft="50dp"
android:layout_marginRight="50dp"
android:background="@color/pating_line"/>
android:id="@+id/et_usernamelogin_password"
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"/>
android:layout_width="match_parent"
android:layout_height="2px"
android:layout_marginLeft="50dp"
android:layout_marginRight="50dp"
android:background="@color/pating_line"/>
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"
/>
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
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
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;
}
}
