我正在爲客戶端自定義Emoji鍵盤。我們已經有一個iOS應用程序,現在試圖在android中做出類似的東西。我使用的是一個類似於iOS中的UICollectionView的gridView。但我根本不明白爲什麼我不能爲gridView設置高度。 我想要實現的是設置特定的鍵盤高度,就像系統鍵盤一樣,所以只顯示8-10張圖像,然後我可以滾動瀏覽其他圖像。添加分頁和水平滾動將是一個獎勵和最後一步。Android設置固定GridView自定義鍵盤高度
下面是鍵盤我的XML文件:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/keyboardView"
android:layout_width="match_parent"
android:layout_height="240dp"
android:background="@android:color/white"
android:orientation="horizontal">
<GridView
android:id="@+id/imageGridView"
android:layout_width="match_parent"
android:layout_height="240dp"
android:columnWidth="90dp"
android:gravity="center"
android:horizontalSpacing="10dp"
android:numColumns="auto_fit"
android:stretchMode="columnWidth"
android:verticalSpacing="10dp" />
</LinearLayout>
我InputServiceManagers onCreateInputView:
public View onCreateInputView() {
keyboardView = getLayoutInflater().inflate(R.layout.keyboard,null);
List<Integer> imageArray = new ArrayList<>();
for (int i = 1; i <= 20;i++){
try {
Class res = R.drawable.class;
String imageName = "sticker" + String.valueOf(i);
Field field = res.getField(imageName);
int drawableID = field.getInt(null);
imageArray.add(drawableID);
} catch (Exception e) {
Log.e("MyTag","Failure to get drawable id.",e);
}
}
imageGrid = (GridView) keyboardView.findViewById(R.id.imageGridView);
imageGrid.setNumColumns(4);
ImageGridAdapter adapter = new ImageGridAdapter(this);
adapter.imageArray = imageArray;
imageGrid.setAdapter(adapter);
return keyboardView;
}
GridViewAdapter:
public class ImageGridAdapter extends BaseAdapter {
private Context mContext;
public List<Integer> imageArray;
public ImageGridAdapter(Context c) {
mContext = c;
}
public int getCount() {
return imageArray.size();
}
public Object getItem(int position) {
return imageArray.get(position);
}
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
if (convertView == null) {
// if it's not recycled, initialize some attributes
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(120, 120));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
//imageView.setPadding(1, 1, 1, 1);
} else {
imageView = (ImageView) convertView;
}
imageView.setImageResource(imageArray.get(position));
return imageView;
}
}
我懷疑你的部分代碼沒有顯示你的問題。如果我膨脹你的佈局文件,我得到一個240dp的高度,但在顯示器的頂部。查看keyboard.xml的父級。 – Gary99
