使用LayoutTransition時某些佈局比其他佈局擴展速度慢其他佈局。更改

我有19個水平線性佈局，在另一個線性佈局中垂直排列。他們幾乎是空的，並點擊顯示文字。我的動畫與佈局使用LayoutTransition時某些佈局比其他佈局擴展速度慢其他佈局。更改

parentOne.getLayoutTransition().enableTransitionType(LayoutTransition.CHANGING);

出於某種原因，第7個佈局似乎比8日開幕的onClick慢一點。只有一秒鐘的時間，但我已經讓其他人在我打開它時要看看它，以確保我沒有發瘋。我會發布整個文件，但它是巨大的，超過了最大允許的文本。所以這裏是肉和土豆。那麼，爲什麼我的佈局打開比其他人慢？數字8-19即刻打開onClick和1-7有一個明顯的小延遲。

一個有不必要的延遲7種Java方法的onClick

private boolean mOpenOne = false; 

public void toggleOne(View view){ 
    TextView stepOne = (TextView)findViewById(R.id.stepOne); 
    ImageView toggle = (ImageView)findViewById(R.id.toggleStepOne); 

    if(mOpenOne){ 
     stepOne.setText("Step 1:"); 
     toggle.setImageResource(R.drawable.open); 
    } 
    else{ 
     stepOne.setText("1. Casualties with an altered mental status should be disarmed immediately."); 
     toggle.setImageResource(R.drawable.close); 
    } 
    mOpenOne = !mOpenOne; 
}

XML與不必要的延遲的onClick

 <LinearLayout 
     android:id="@+id/TFCLayoutOne"

好吧，我想通了作品的佈局之一。它看起來好像是一個處理問題。如果我不得不猜測，我會說每次我調用一個方法時，它都會搜索onCreate方法中巨大的linearlayouts列表以便將其打開。

以我onCreate方法我定義線性佈局的CRAP TON這樣

LinearLayout parentOne = (LinearLayout) findViewById(R.id.TFCLayoutOne); 
parentOne.getLayoutTransition().enableTransitionType(LayoutTransition.CHANGING);

解決方法：

我分離所有這些，將它們放置在所有它們各自的onClick方法。現在，當我點擊它們時，它們實際上打開的速度比我設置的其他頁面快，所以我也會改變它們。我的Java方法是：

private boolean mOpenOne = false; 

public void toggleOne(View view){ 
TextView stepOne = (TextView)findViewById(R.id.stepOne); 
ImageView toggle = (ImageView)findViewById(R.id.toggleStepOne); 

if(mOpenOne){ 
    stepOne.setText("Step 1:"); 
    toggle.setImageResource(R.drawable.open); 
} 
else{ 
    stepOne.setText("1. Casualties with an altered mental status should be disarmed immediately."); 
    toggle.setImageResource(R.drawable.close); 
} 
mOpenOne = !mOpenOne;

}

我讓他們改爲：

private boolean mOpenOne = false; 

public void toggleOne(View view){ 
    TextView stepOne = (TextView)findViewById(R.id.stepOne); 
    ImageView toggle = (ImageView)findViewById(R.id.toggleStepOne); 
    LinearLayout parentOne = (LinearLayout) findViewById(R.id.TFCLayoutOne); 
    parentOne.getLayoutTransition().enableTransitionType(LayoutTransition.CHANGING); 

    if(mOpenOne){ 
     stepOne.setText("Step 1:"); 
     toggle.setImageResource(R.drawable.open); 
    } 
    else{ 
     stepOne.setText("1. Casualties with an altered mental status should be disarmed immediately."); 
     toggle.setImageResource(R.drawable.close); 
    } 
    mOpenOne = !mOpenOne; 
}

希望這會幫助別人！
