Android-Get Background color of listview(item) programmatically

问题

First I create a background color for listview items like below, I have two custom listview like this:

My custom list for setting color:

Code:

@Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        Holder holder = new Holder();
        final View rowView;
        rowView = inflater.inflate(R.layout.table_one, null);
        holder.tv = (TextView) rowView.findViewById(R.id.textView1);
        holder.tv.setText(result[position]);
        rowView.setBackgroundColor(Color.WHITE);
        rowView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                if (position == 0) {
                    rowView.setBackgroundColor(Color.BLUE);
                    MainActivity.counter = Color.BLUE;
                } else if (position == 1) {
                    rowView.setBackgroundColor(Color.YELLOW);
                    MainActivity.counter = Color.YELLOW;
                } else if (position == 2) {
                    rowView.setBackgroundColor(Color.GREEN);
                    MainActivity.counter = Color.GREEN;
                } else if (position == 3) {
                    rowView.setBackgroundColor(Color.MAGENTA);
                    MainActivity.counter = Color.MAGENTA;
                }
            }
        });
        return rowView;
    }

                Toast.makeText(getApplicationContext(), "Checked", Toast.LENGTH_SHORT).show();
            }
        });

回答1:

If you want to obtain a view background colour, from a ListView

ListView listView = (ListView) findViewById(R.id.my_list);

to obtain background try

Drawable listDrawableBackground = listView.getBackground();

if background is a colour, to obtain the colour, you can try

ColorDrawable listViewColor = (ColorDrawable) listView.getBackground();

to get the actual colour, use

int colorId = listViewColor.getColor();

you can compare this colorId with existing color like so:

if (colorID == R.color.blue) { Log("color is blue"); }

Another way will be to add a tag to the ListView, and the tag will be the color, say

tag = "#ccc", and you can use

String colorCode = (String)listView.getTag();

now you have the colorCode and you can reuse it anywhere in your program.
