我在這裏創建一個動態佈局。我有一個父級佈局,我在其中添加所有動態創建的視圖。現在點擊特定視圖我需要位置。如何獲得在主線性佈局中動態創建的視圖位置?
根據那個位置我必須發送包含這個視圖的JsonObject在Android中。在這裏,我無法獲得確切的觀點。
這是我的代碼:
int len = result.length();
View addView;
if (!(len == 0)) {
finalResult.clear();
for (int i = 0; i <= len; i++) {
try {
finalResult.add(result.getJSONObject(i));
} catch (JSONException e) {
e.printStackTrace();
}
}
for (int i = 0; i < result.length(); i++) {
JSONObject obj = result.getJSONObject(i);
if (i == 0) {
addView = mInflater.inflate(R.layout.sightseeing_firstview, null);
image = (ImageView) addView.findViewById(R.id.imagesightseeing_first);
textview = (TextView) addView.findViewById(R.id.textView1);
llfirst = (LinearLayout) addView.findViewById(R.id.llfirstview);
llayout.addView(addView);
String category1 = finalResult.get(i).getString("CategoryName");
imageurl1 = finalResult.get(i).getString("ImageUrl");
((BaseActivity) SightseeingToursActivity.this).imageLoader.displayImage(imageurl1, image,
Common.optionsSmall);
textview.setText(category1);
} else if (i % 5 == 0) {
addView = mInflater.inflate(R.layout.sightseeing_firstview, null);
images = (ImageView) addView.findViewById(R.id.imagesightseeing_first);
textview = (TextView) addView.findViewById(R.id.textView1);
llfirst = (LinearLayout) addView.findViewById(R.id.llfirstview);
llayout.addView(addView);
String category1 = finalResult.get(i).getString("CategoryName");
imageurlss = finalResult.get(i).getString("ImageUrl");
((BaseActivity) SightseeingToursActivity.this).imageLoader.displayImage(imageurlss, images,
Common.optionsSmall);
textview.setText(category1);
} else {
addView = mInflater.inflate(R.layout.sightseeing_secondview, null);
iv = (ImageView) addView.findViewById(R.id.secondimagesightseeing_second);
tv = (TextView) addView.findViewById(R.id.textView2);
llsecond = (LinearLayout) addView.findViewById(R.id.llsecondview);
String category2 = finalResult.get(i).getString("CategoryName");
imageurl2 = finalResult.get(i).getString("ImageUrl");
((BaseActivity) SightseeingToursActivity.this).imageLoader.displayImage(imageurl2, iv,
Common.optionsSmall);
tv.setText(category2);
if (result.length() > i + 1) {
i++;
ivview = (ImageView) addView.findViewById(R.id.secondimagesightseeing_third);
text = (TextView) addView.findViewById(R.id.textView3);
llthird = (LinearLayout) addView.findViewById(R.id.llthirdview);
String category3 = finalResult.get(i).getString("CategoryName");
imageurl3 = finalResult.get(i).getString("ImageUrl");
((BaseActivity) SightseeingToursActivity.this).imageLoader.displayImage(imageurl3, ivview,
Common.optionsSmall);
text.setText(category3);
}
llayout.addView(addView);
}
position = llayout.indexOfChild(addView);
addView.setTag(position);
addView.setOnClickListener(this);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void onClick(View v) {
position = (Integer) v.getTag();
Toast.makeText(SightseeingToursActivity.this, "Position" + position, Toast.LENGTH_SHORT).show();
try {
Intent in = new Intent(SightseeingToursActivity.this, sightseeing_list.class);
in.putExtra("TourList", result.getJSONObject(position).toString());
startActivity(in);
} catch (Exception e) {
}
}
看起來像'llayout.addView(addView);'應該是最後'else'塊之外。也就是說,將它移到'else'的右括號後面的'position = llayout.indexOfChild(addView);'之前。 –
嗨邁克...我還沒有得到確切的位置。有兩種佈局。第一種,我加入單個圖像,在第二種佈局中,我有兩個圖像horizontal.Sequence是一個圖像填充父,然後第二個佈局,兩個圖像,再次兩個圖像,然後下一個圖像,這是重複的。現在我想點擊每個圖像的位置。 –
你已經在添加視圖後編寫了設置標記語句,所以在添加視圖之前將其寫入 – Vickyexpert
