安卓之listview和textview爭搶焦點的解決辦法

標籤：焦點爭搶

     尋找了網上很多文章，說是在XML檔案設定textview的focus為false ，簡直是一派胡言，那樣連文本都輸入不了了，有何用

網上尋找無果，改用java代碼控制listview的longclick方法，實現彈出複製和刪除listview的辦法

自訂一個popWindow 

private void initPopupWindow(LayoutInflater inflater) {
View view = inflater.inflate(R.layout.pop_item_layout, null);
popupWindow = new PopupWindow(view, 100, 50);
// popupWindow.setWidth(LayoutParams.WRAP_CONTENT);                  
// popupWindow.setHeight(LayoutParams.WRAP_CONTENT); 
copyTv = (TextView) view.findViewById(R.id.pop_copy_tv);
deleteTv = (TextView) view.findViewById(R.id.pop_delete_tv);
}

然後自己寫一個監聽方法

class tvOnTouch implements OnTouchListener {
private Context mContext;
private int mPosition;


public tvOnTouch(Context context, int position) {
// TODO Auto-generated method stub
this.mContext = context;
this.mPosition = position;
}


@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
if (v.getId() == R.id.pop_copy_tv) {
TextView tv = (TextView) v;
if (event.getAction() == MotionEvent.ACTION_DOWN) {// 按下
tv.setTextColor(0xff00CD66);
} else if (event.getAction() == MotionEvent.ACTION_UP) {// 彈起
tv.setTextColor(0xffffffff);

com.robot.utils.TextManager.copyText(mContext, mDatas.get(mPosition).getMsg());
Toast.makeText(mContext, "複製成功", SHOW_TIME).show();


if (popupWindow != null) {
popupWindow.dismiss();
}
}
} else {
TextView tv = (TextView) v;
if (event.getAction() == MotionEvent.ACTION_DOWN) {// 按下
tv.setTextColor(0xff00CD66);
} else if (event.getAction() == MotionEvent.ACTION_UP) {// 談起
tv.setTextColor(0xffffffff);
mDatas.remove(mPosition);
notifyDataSetChanged();
Toast.makeText(mContext, "刪除成功", SHOW_TIME).show();

if (popupWindow != null) {
popupWindow.dismiss();
}
}
}
return true;
}


}

最後在getview裡加入監聽事件

viewHolder.content.setOnLongClickListener(new OnLongClickListener() {


@Override
public boolean onLongClick(View v) {
// TODO Auto-generated method stub
showPop(v);
copyTv.setOnTouchListener(new tvOnTouch(mContext, position));
deleteTv.setOnTouchListener(new tvOnTouch(mContext, position));
return false;
}
});
