Android自定義水波紋底部導航的實現(xiàn)
更新時間：2022年08月10日 15:32:31 作者：寫的都是BUG
TabLayout作為導航組件來說，使用場景非常的多，也意味著要滿足各種各樣的需求，這篇文章主要介紹了Android自定義水波紋底部導航的實現(xiàn)
今天給大家?guī)硪粋€自定義的底部導航，我不會做動圖，只能搞一張圖片給大家看看，大家見諒
這個就是自定義的tablayout底部搞好的樣式了
TabLayout提供了一個水平布局用于展示tabs，繼承自HorizontalScrollView。一般與Viewpager結(jié)合使用實現(xiàn)頁面和標簽聯(lián)動的效果，是時下APP中非常常用的一個控件
首先我們需要創(chuàng)建一個類或者是模塊都可以

// 屬性動畫

}
@Override
public void stop() {
mValueAnimator.end();
}
@Override
public boolean isRunning() {
return mValueAnimator != null && mValueAnimator.isRunning();
}
}然后創(chuàng)建我們的TabFragment
package com.example.map.tab;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import androidx.annotation.Nullable;
import androidx.fragment.app.Fragment;
import com.example.map.R;
/**

*/
public class TabFragment extends Fragment {
public static final String FRAG_KEY = "FragKey";
private TextView mFragTabText;
private void assignViews(View view) {
mFragTabText = (TextView) view.findViewById(R.id.frag_tab_text);
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_tab, null);
assignViews(view);
return view;
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
if (getArguments() != null) {
String title = getArguments().getString(FRAG_KEY);
mFragTabText.setText(title);
}
}
}然后創(chuàng)建一個動畫的幫助類
package com.example.map.tab;
import android.animation.AnimatorSet;
import android.animation.ArgbEvaluator;

public class TabAnimHelper {

float animatedValue = (float) valueAnimator.getAnimatedValue();
view.setPadding(view.getPaddingLeft(),
(int) animatedValue,
view.getPaddingRight(),
view.getPaddingBottom());
}
});
animator.start();
}
/**

* @param from
* @param to
*/
public static void changeTextSize(final TextView textView, float from, float to) {
ValueAnimator textSizeChangeAnimator = ValueAnimator.ofFloat(from, to);
textSizeChangeAnimator.setDuration(150);
textSizeChangeAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
@Override
public void onAnimationUpdate(ValueAnimator valueAnimator) {
textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, (float) valueAnimator.getAnimatedValue());
}
});
textSizeChangeAnimator.start();
}
/**

*/

changeTextColorAnimation.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
@Override
public void onAnimationUpdate(ValueAnimator animator) {
textView.setTextColor((Integer) animator.getAnimatedValue());
}
});
changeTextColorAnimation.start();
}
/**
* 改變視圖大小
* @param image
* @param fromScale
* @param toScale
*/
public static void changeImageSize(ImageView image, float fromScale, float toScale) {
ObjectAnimator scaleX;
ObjectAnimator scaleY;
scaleX = ObjectAnimator.ofFloat(image, "scaleX", fromScale, toScale);
scaleY = ObjectAnimator.ofFloat(image, "scaleY", fromScale, toScale);
AnimatorSet set = new AnimatorSet();
set.setDuration(150);
set.playTogether(scaleX, scaleY);
set.start();
}
/**

*/
@SuppressWarnings("deprecation")
public static void clipDrawable(final View image, Drawable drawable, boolean isActivated) {
if (drawable == null) {
return;
}
if (isActivated) {
final ClipDrawable scaleDrawable = new ClipDrawable(drawable, Gravity.CENTER,
ClipDrawable.HORIZONTAL | ClipDrawable.VERTICAL);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
image.setBackground(scaleDrawable);
} else {

}
image.setBackgroundDrawable(scaleDrawable);
ValueAnimator animator = ValueAnimator.ofInt(0, 10000);
animator.setDuration(200);
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
@Override
public void onAnimationUpdate(ValueAnimator animation) {

});
animator.start();
} else {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
image.setBackground(null);

image.setBackgroundDrawable(null);
}
}
}
/**

*/
@SuppressWarnings("deprecation")
public static void rippleDrawable(final View view, int frontColor, int behindColor, int mode, boolean isActivated) {

}
} else {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
view.setBackground(null);
} else {
view.setBackgroundDrawable(null);
}
}
}
}還有一個item的實體類
package com.example.map.tab;
import android.graphics.drawable.Drawable;
/**
* Created by long on 2022/5/10.
* Tab項
*/
public class TabItem {
private String title;
private Drawable drawable;
private int imageRes;
public TabItem(String title, Drawable drawable, int imageRes) {
this.title = title;
this.drawable = drawable;
this.imageRes = imageRes;
}
public TabItem(String title, int imageRes) {
this.title = title;
this.drawable = null;
this.imageRes = imageRes;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public Drawable getDrawable() {
return drawable;
}
public void setDrawable(Drawable drawable) {
this.drawable = drawable;
}
public int getImageRes() {
return imageRes;
}
public void setImageRes(int imageRes) {
this.imageRes = imageRes;
}
}然后在我們的Activity中進行一個引用，首先在是我們Activity的一個布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical">
<FrameLayout
android:id="@+id/relate_tab_content"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<TextView
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="@drawable/shadow" />
<com.example.map.tab.XFragmentTabHost
android:id="@android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp" />
</com.example.map.tab.XFragmentTabHost>
</LinearLayout>然后在我們的Activity中進行一個應(yīng)用控件
package com.example.map.ui.activity;
import android.graphics.Color;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;
import androidx.appcompat.app.AppCompatActivity;
import com.bumptech.glide.Glide;

import com.llw.network.observer.BaseObserver;
import com.llw.network.utils.KLog;
import com.youth.banner.Banner;
import com.youth.banner.BannerConfig;
import com.youth.banner.Transformer;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
public class QihooActivity extends AppCompatActivity {
private XFragmentTabHost mTabHost;
//底部導航的名稱
String[] mTabTitle = new String[]{"首頁", "游戲", "軟件", "應(yīng)用圈", "管理"};
//文字上的圖片
int[] mImageResId = new int[]{R.drawable.sel_360_home, R.drawable.sel_360_game, R.drawable.sel_360_software,
R.drawable.sel_360_app, R.drawable.sel_360_mag};
//創(chuàng)建的幾個fragment
Class[] mFragClass = new Class[]{Fragment1.class, Fragment2.class,
Fragment3.class, Fragment4.class, Fragment5.class};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_qihoo);
initTabHost();
}
private void initTabHost() {
mTabHost = (XFragmentTabHost) findViewById(android.R.id.tabhost);
mTabHost.setup(this, getSupportFragmentManager(), R.id.relate_tab_content);
mTabHost.setTabMode(XFragmentTabHost.TabMode.Ripple);
mTabHost.setTextActiveColor(Color.WHITE);
mTabHost.setTextInactiveColor(Color.GRAY);
// mTabHost.setFrontColor(Color.RED);
// mTabHost.setBehindColor(Color.GREEN);
for (int i = 0; i < mFragClass.length; i++) {
Bundle bundle = new Bundle();
bundle.putString(TabFragment.FRAG_KEY, mTabTitle[i]);
mTabHost.addTabItem(new TabItem(mTabTitle[i], mImageResId[i]),
mFragClass[i], bundle);
}
}
