3.这个效果只有一条 但是感觉轻量级~

粘完了 觉得还行 也没想的那么好~~~

2.attr 手动设置的也就这了
<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="FadingTextView">
<attr name="texts" format="string" />
<attr name="timeout" format="integer" />
</declare-styleable>
</resources>3.fadein 哦~动画也能改改 仅限补间动画
<?xml version="1.0" encoding="UTF-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha
android:duration="@android:integer/config_longAnimTime"
android:fromAlpha="0.0"
android:interpolator="@android:anim/linear_interpolator"
android:toAlpha="1.0" />
</set>
fadeout
<?xml version="1.0" encoding="UTF-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha
android:duration="@android:integer/config_longAnimTime"
android:fromAlpha="1.0"
android:interpolator="@android:anim/anticipate_interpolator"
android:toAlpha="0.0" />
</set>
4.xml 和 代码 同时设置 时间的话 会G 建议XML
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<com.as.textview_san.FadingTextView
android:id="@+id/fadingTextView"
style="@style/TextAppearance.AppCompat.Headline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
app:timeout="5000"
/>
</LinearLayout>5.
public class MainActivity extends AppCompatActivity {

FadingTextView fadingTextView = findViewById(R.id.fadingTextView);
String[] str=new String[6];
str[0]="hahhfahafhafa";
