前言

比如在進(jìn)行登錄的操作中，用戶輸入完密碼之后，肯定是想直接點(diǎn)擊登錄按鈕的。返回鍵隱藏軟鍵盤這樣的體驗(yàn)肯定很糟糕，程序員，遇到問題解決問題。

xml

java

mScrollView=(ScrollView)view.findViewById(R.id.scrollview);usernamelogin_username.setOnTouchListener(newView.OnTouchListener(){@OverridepublicbooleanonTouch(Viewv,MotionEventevent){changeScrollView();returnfalse;}});usernamelogin_password.setOnTouchListener(newView.OnTouchListener(){@OverridepublicbooleanonTouch(Viewv,MotionEventevent){changeScrollView();returnfalse;}});

%20/**%20*使ScrollView指向底部%20*/%20privatevoidchangeScrollView(){%20newHandler().postDelayed(newRunnable(){%20@Override%20publicvoidrun(){%20mScrollView.scrollTo(0,mScrollView.getHeight());%20}%20},300);%20}

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"/>

或者直接在代碼中

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;//頭部ImageView@OverrideprotectedvoidonCreate(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);/***當(dāng)輸入被點(diǎn)擊*/et_name.setOnTouchListener(newView.OnTouchListener(){@OverridepublicbooleanonTouch(Viewv,MotionEventevent){start();returnfalse;}});btn.setEnabled(false);btn.setOnClickListener(newView.OnClickListener(){@OverridepublicvoidonClick(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);//設(shè)置重復(fù)次數(shù)mHead.startAnimation(scaleAnimation);newHandler().postDelayed(newRunnable(){@Overridepublicvoidrun(){mHead.setVisibility(View.GONE);}},500);}/***菜單、返回鍵響應(yīng)*/@OverridepublicbooleanonKeyDown(intkeyCode,KeyEventevent){//TODOAuto-generatedmethodstubif(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; }}
