Android RelativeLayout.LayoutParams無法投射到AbsListview.LayoutParams（錯誤低於4.4.4）在5.0和6.0.1上正常工作

我已使用ListView，而xml中的父項爲RelativeLayout。當我在4.4.4上運行應用程序時，它給了我ClassCastException，但是當我在5.0.1或6.0.1上運行它時，它運行時沒有任何錯誤。請查看代碼片段。Android RelativeLayout.LayoutParams無法投射到AbsListview.LayoutParams（錯誤低於4.4.4）在5.0和6.0.1上正常工作

每個人都在暗示編輯代碼..請你給一個解？ –

編輯使您的問題更具可讀性，以實際獲得更快的解決方案。 –

請檢查答案。 –

holder.profileImageIV.setLayoutParams(params); 
convertView.setLayoutParams(params);

如果您需要修改現有佈局參數，可以用getLayoutParams()訪問它們，進行修改，然後調用requestLayout()以通知的佈局發生了變化。

所以，與其

convertView.setLayoutParams(params);

你可以試試這個

LayoutParams params = convertView.getLayoutParams(); 
int margin = Utils.getInstance().dpToPx(mContext, 5); 
params.setMargins(margin, margin, margin, margin); 
convertView.requestLayout();

做同樣的事情在ImageView

java.lang.ClassCastException：android.widget.AbsListView $ LayoutParams不能轉換爲android.widget.RelativeLayout $ LayoutParams –

這裏您將用更通用的RelativeLayout.LayoutParams替換正確類型AbsListView.LayoutParams的現有佈局參數。

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, Utils.getInstance().dpToPx(mContext, 260));

檢查此零件。嘗試添加AbsListView.LayoutParams的LayoutParams。嘗試一下，讓我知道。

如果您需要修改現有佈局參數，請使用getLayoutParams()訪問它們，對其進行修改，然後致電requestLayout()通知佈局已更改。

我已經在xml中使用RelativeLayout作爲父項。我也嘗試過AbsListView.LayoutParams，但它給了我異常，AbsListView.LayoutParams不能轉換爲RelativeLayout.LayoutParams –

Android RelativeLayout.LayoutParams無法投射到AbsListview.LayoutParams（錯誤低於4.4.4）在5.0和6.0.1上正常工作
