我正在尝试使用设置文本背景颜色 text1.setBackgroundColor(Color.rgb(r,g,b));

是红色,绿色,蓝色值来自数据库基于值编程i设置r=128,g=255,b=128它颜色是暗绿色但我运行程序它将显示红色

for(int i = 0; i < list.length(); i++){
            JSONObject c = list.getJSONObject(i);

            // Storing each json item in variable
           // String GRPCODE = c.getString(TAG_GRPCODE);
            String GRPNAME = c.getString(TAG_GRPNAME);
            String QTY = c.getString(TAG_QNT);
            String BUDGET = c.getString(TAG_BUDGET);
            String STOCK = c.getString(TAG_STOCK);
            String DIFF = c.getString(TAG_DIFF);
            String DIFF_P = c.getString(TAG_DIFF_P);

             COLOR = c.getString(TAG_COLOR);

            /*String[] ARGB = COLOR.split(" ");

             String V1=ARGB[0];
             String V2=ARGB[1];
             String V3=ARGB[2];
             String V4=ARGB[3];

             a=Integer.parseInt(V1);
             r=Integer.parseInt(V2);
             g=Integer.parseInt(V3);
             b=Integer.parseInt(V4);*/

你是Android的新手如何以编程方式为另一个xml文件设置文本背景颜色我已经使用设置内容视图添加xml文件,但它只有listview,我有另一个xml文件使用模块执行文件,我想文本背景在modelo xml文件中

public void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main1);
    EXECUTAR = (Button) findViewById(R.id.btn_buscar);
    ValorBusca = (EditText) findViewById(R.id.txt_buscar);
    Lista = (ListView) findViewById(R.id.listView1);
    ValorBusca.setText("");
    EXECUTAR.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            QuerySQL(null);
        }
    });
}
    public  void QuerySQL(String COMANDOSQL) {
    ResultSet rs;
    try {
        Statement statement = ma.connect.createStatement();
        rs = statement.executeQuery("SELECT * FROM "+ValorBusca.getText().toString()+"");
        List<Map<String, String>> data = null;
        data = new ArrayList<Map<String, String>>();
        while(rs.next()) {
            Map<String, String> datanum =new …

如何将ARGB(255 0 255 0)颜色转换为HEXADECIMAL颜色。我在数据库中有 ARGB 颜色，我使用 JSON 格式的网络服务进行检索。
我想在文本字段中添加颜色TAG_DIFF_P (R.id.l7)

这是我的代码，如何在文本字段的背景中添加颜色

try {

        JSONObject json1 = jParser.getJSONFromUrl(myUrl);
        // Getting Array of Contacts
        JSONArray list = json1.getJSONArray(TAG_JSONDataResult);


        // looping through All Contacts
        for(int i = 0; i < list.length(); i++){
            JSONObject c = list.getJSONObject(i);


            String GRPNAME = c.getString(TAG_GRPNAME);
            String QTY = c.getString(TAG_QNT);
            String BUDGET = c.getString(TAG_BUDGET);
            String STOCK = c.getString(TAG_STOCK);
            String DIFF = c.getString(TAG_DIFF);
            String DIFF_P = c.getString(TAG_DIFF_P);                
            String COLOR = c.getString(TAG_COLOR);
