如何在android studio中为textView中的文本创建淡入动画？

Question

也许有人已经有了现成的解决方案，或者可以告诉我如何在 android studio 中制作类似的动画？

淡入文字动画

我在html + CSS中找到了一个例子，但我不知道是否有任何方法可以将其应用到TextView？如果有人遇到并找到解决方案，我将非常感激。

试试这个

<TextView
    android:id="@+id/typewriter_text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="24sp"
    android:textColor="#000000"
    android:layout_gravity="center"
    android:text="Your text will appear here"
    />

活动

import android.os.Bundle;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;

public class TypewriterActivity extends AppCompatActivity {

    private TextView typewriterText;
    private String[] textArray;
    private int currentIndex = 0;
    private Handler handler = new Handler();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_typewriter);

        typewriterText = findViewById(R.id.typewriter_text);
        // Split the text into an array of words
        textArray = getResources().getStringArray(R.array.typewriter_text_array);
        
        // Start the typewriter effect
        startTypewriterAnimation();
    }

    private void startTypewriterAnimation() {
        if (currentIndex < textArray.length) {
            String currentText = textArray[currentIndex];
            typewriterText.setText(currentText.subSequence(0, currentText.length() - 1));
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                    startTypewriterAnimation();
                }
            }, 100); // Delay between characters (adjust as needed)
            currentIndex++;
        }
    }
}
