升级Android Studio后,Android ValueAnimator不会协调一致地进行动画

垚tutu 2019-11-28 19:27:29 1656

我已经开始开发一个android应用程序,该应用程序应该显示淡出的文本以及一个圆形动画,并且在我升级Android Studio和所有相关组件之前,它一直很好地工作。现在开始,然后过一会儿停止。

活动代码:

package authenticator.cloudy.sh;

import android.animation.Animator;
import android.animation.AnimatorListenerAdapter;
import android.animation.ArgbEvaluator;
import android.animation.ValueAnimator;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.TextView;

public class AuthCodeDisplayActivity extends AppCompatActivity
{
    private static final int TIMER_LENGTH = 60;

    private String login_session = "";
    private TimerView mTimerView;
    private TextView code = null;

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.main_menu, menu);
        return true;
    }

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

        mTimerView = findViewById(R.id.tvIndicator);

        code = findViewById(R.id.tvCode);
        login_session = getIntent().getStringExtra("session_id");

        String authcode = getAuthCode(login_session);
        code.setText(authcode);

        int colorFrom = getResources().getColor(R.color.green);
        int colorTo = getResources().getColor(R.color.lightGray);
        final ValueAnimator colorAnimation = ValueAnimator.ofObject(new ArgbEvaluator(), colorFrom, colorTo);
        colorAnimation.setRepeatCount(0);
        colorAnimation.setRepeatMode(ValueAnimator.RESTART);
        colorAnimation.setDuration(60000); // milliseconds. Wait a full minute

        colorAnimation.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
            @Override
            public void onAnimationUpdate(ValueAnimator animator) {
                code.setTextColor((int) animator.getAnimatedValue());
            }
        });

        colorAnimation.addListener(new AnimatorListenerAdapter()
        {
            @Override
            public void onAnimationEnd(Animator animation)
            {
                String authcode = getAuthCode(login_session);
                code.setText(authcode);
                colorAnimation.cancel();
                colorAnimation.start();
                mTimerView.stop();
                mTimerView.start(TIMER_LENGTH);
            }
        });

        mTimerView.start(TIMER_LENGTH);
        colorAnimation.start();
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle item selection
        switch (item.getItemId()) {
            case R.id.action_logout:
                Intent it = new Intent(this, LoginActivity.class);
                startActivity(it);
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
    }

    public native String getAuthCode(String login_session);

}

动画停在随机无关的位置...

由于我处于Android开发的初级阶段(这或多或少是我的学习项目),所以我真的不知道下一步要做什么,所以请您在这里张贴我拥有的所有代码(TimerView大致相同于:https : //github.com/puercos/puercos-android/blob/master/app/src/main/java/com/puercos/puercos/components/timerView/TimerView.java),有人对正在发生的事情有一个想法,可以给出一些指示。
