我有一些片段,其中内部视图被动态膨胀并添加到线性布局中以形成类似于列表视图的东西。这在高端设备上运行良好,但在中低级设备上,动画有非常明显的延迟,有时动画会被完全跳过。我尝试在谷歌上搜索了一下,但在涉及到与膨胀视图相关的过渡动画以及如何在此过程中处理动态视图膨胀的提示时,没有遇到任何具体的问题。
回顾一下......用户按下一个按钮,一个片段进入视图,视图动态膨胀,动画滞后或被跳过。如果可能的话,我真的很想让一切顺利。
编辑:一些示例代码
public static void addPersonRow(PersonObject po){
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, 50);
params.setMargins(0, 5, 0, 5);
final View view = IncidentReport_v2.ir2.getLayoutInflater().inflate(R.layout.ir_involved_people_row, null);
view.setLayoutParams(params);
view.setTag(po.originalName);
RelativeLayout rl = (RelativeLayout) view.findViewById(R.id.ir_involved_ppl_add_row_rl);
TextView name = (TextView) view.findViewById(R.id.ir_involved_ppl_name_txt);
name.setText(po.firstName+" "+po.lastName);
ImageButton open = (ImageButton) view.findViewById(R.id.ir_involved_ppl_reopen_btn);
Bundle b = new Bundle();
b.putParcelable("personObj", po);
open.setTag(b);
name.setTag(b);
rl.setTag(b);
OnClickListener openClick = new OnClickListener() {
@Override
public void onClick(View v) {
pplAddFrag = new IR_PeopleInvolved_AddForm_Fragment();
Bundle b = new Bundle();
b.putParcelable("existingPerson", (Bundle)v.getTag());
pplAddFrag.setArguments(b);
android.support.v4.app.FragmentManager fragmentManager = IncidentReport_v2.ir2.getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.setCustomAnimations(R.anim.bounce, R.anim.bounce_out, R.anim.bounce, R.anim.bounce_out);
fragmentTransaction.add(R.id.ir_main_frame, pplAddFrag, "pplAddFrag");
fragmentTransaction.addToBackStack("pplAddFrag");
fragmentTransaction.commit();
IncidentReport_v2.theMenu.removeItem(R.id.incident_report_save);
IncidentReport_v2.ir2.invalidateOptionsMenu();
}
};
open.setOnClickListener(openClick);
name.setOnClickListener(openClick);
rl.setOnClickListener(openClick);
ImageButton delete = (ImageButton) view.findViewById(R.id.ir_involved_ppl_delete_btn);
delete.setTag(po);
delete.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
pplHolder.removeView(view);
IncidentReport_v2.people.remove((PersonObject)v.getTag());
IR_InvolvedFragment.pplCounterTxt.setText(IncidentReport_v2.people.size()+"");
}
});
pplHolder.addView(view);
if(!IncidentReport_v2.people.contains(po)){
IncidentReport_v2.people.add(po);
}
IR_InvolvedFragment.pplTxt.setTextColor(IncidentReport_v2.ir2.getResources().getColor(R.color.green));
IR_InvolvedFragment.pplCounterTxt.setText(IncidentReport_v2.people.size()+"");
}
这取决于我有多少 personObjects 在 for 循环内调用
