Hi, new to android, how to set the background color of the text for another xml file in the program, I already add the xml file using the content view, but it only has listview and I have another xml file using the module to execute the file. I want to background text in xml model file

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 HashMap<String, String>(); datanum.put("A",rs.getString(1)); datanum.put("B",rs.getString(2)); datanum.put("c",rs.getString(3)); data.add(datanum); } String[] from = {"A","B","c"}; int[] views = {R.id.txttitulo,R.id.txtconteudo,R.id.textview3}; AD = new SimpleAdapter(this, data, R.layout.modelo, from, views); Lista.setAdapter(AD); } catch (Exception e) { Log.e("ERRO",e.getMessage()); Toast.makeText(getBaseContext(),"Enter Table Name",Toast.LENGTH_SHORT).show(); } }

 <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:stretchColumns="0,1,2" > <TableRow android:id="@+id/tableRow1" android:layout_width="2dip" android:scrollbarAlwaysDrawHorizontalTrack="true" android:layout_height="wrap_content"> <TextView android:id="@+id/txttitulo" android:text="Name" android:layout_height="wrap_content" android:layout_width="2dip" android:gravity="left" android:background="@drawable/cell_shape" android:padding="5dip" android:layout_marginLeft="3dp" android:textColor="#0174DF"/> <TextView android:id="@+id/txtconteudo" android:text="Number" android:layout_height="wrap_content" android:layout_width="2dip" android:gravity="left" android:textColor="#0174DF" android:background="@drawable/cell_shape" android:padding="5dip" /> <TextView android:id="@+id/textview3" android:text="Number" android:layout_height="wrap_content" android:layout_width="2dip" android:gravity="right" android:layout_weight="1" android:textColor="#0174DF" android:background="@drawable/cell_shape" android:padding="5dip" android:layout_marginRight="3dp"/> </TableRow> 

Answer 1

try this way. Just override the getView() method of your adapter. And change the color from there.

 AD = new SimpleAdapter(this, data, R.layout.modelo, from, views){ @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.modelo, null); } TextView text1 = (TextView) v.findViewById(R.id.txttitulo); TextView text2 = (TextView) v.findViewById(R.id.txtconteudo); TextView text3 = (TextView) v.findViewById(R.id.textview3); text1.setTextColor(Color.GREEN); text2.setTextColor(Color.GREEN); text3.setTextColor(Color.GREEN); return super.getView(position, v, parent); } }; 

Hope this helps you.

Check this,

 TextView textView = (TextView) findViewById(R.id.text1); textView.setText("Welcome"); textView.setTextColor(Color.WHITE); textView.setBackgroundColor(Color.RED);

It can help you.

 textview.setBackgroundResource(R.color.white); 

Note : instead of textview you need to write the name TextView object .

try it

 View v=findViewById(R.layout.modelo); TextView tv=(TextView)v.findViewById(R.id.txttitulo); tv.setBackgroundColor(Color.RED);
