應用程序保持凍結，Android Studio錯誤？

Question

在這個應用程序中，我試圖獲得一個小的Button來在屏幕上移動，並讓用戶嘗試避免緩慢落在屏幕上的塊。

XML布局：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

動畫布局：

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:fromXDelta="0"
        android:duration="150"
        android:toXDelta="100"
        android:repeatCount="1"
        android:repeatMode="reverse"/>
</set>

<?xml version="1.0" encoding="utf-8"?>

        android:toXDelta="-100"
        android:repeatCount="1"
        android:repeatMode="reverse"/>
</set>
<?xml version="1.0" encoding="utf-8"?>

        android:fromYDelta="400"
        android:toYDelta="0"/>
</set>

其余大多數文件都是相似的。 這些文件為點​​之間的過渡設置動畫。 該按鈕將在三個不同區域之間移動。 這意味着動畫並不是那么重要，因為它們可以工作，並且當我單擊文本視圖時，應用程序會凍結。 這也是在調用主循環時。 這可能是問題嗎？

當我在具有足夠內存和內存的三星s5上運行該應用程序時，程序凍結，出現錯誤並指出該應用程序已停止工作。

有任何想法嗎？

Answer 1

永不-永不-永不做

1）

 try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }

2）做while (true)循環

3）進行長時間/繁重的操作（例如網絡通話）

在UI線程中。

該線程（也稱為主線程）負責更新應用程序接口。 系統會定期檢查線程是否可以響應。 因此，如果線程無法回答（由於我上面提到的原因），則會引發ANR（應用程序無響應）異常。
