    <p>i've created an android application which creates 50 button dynamically,which works perfectly, but the problem is that i can't put some background color for these buttons dynamically using code like</p> <pre><code>buttons[i][j].setTextColor(getResources().getColor(R.color.mycolor)); buttons[i][j].setBackgroundColor(getResources().getColor(R.color.mycolor)); </code></pre> <p>my code is as given below, can anyone please tell me some solution for giving background color for button</p> <pre><code>import android.app.Activity; import android.os.Bundle; import android.view.ViewGroup.LayoutParams; import android.widget.Button; import android.widget.LinearLayout; public class MyMain extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.mymain); createCalender(); } public void createCalender() { LinearLayout layoutVertical = (LinearLayout) findViewById(R.id.liVLayout); LinearLayout.LayoutParams param = new LinearLayout.LayoutParams( LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT, 1.0f); LinearLayout rowLayout=null; Button[][] buttons = new Button[10][5]; int count=51; int tab=1; for (int i = 0; i&lt;10; i++) { if(count%5==1) { rowLayout = new LinearLayout(this); rowLayout.setWeightSum(5); layoutVertical.addView(rowLayout,param); count=count-5; } for(int j=0;j&lt;5;j++) { buttons[i][j]=new Button(this); buttons[i][j].setText(""+tab); buttons[i][j].setHeight(35); buttons[i[j].setWidth(75); buttons[i][j].setBackgroundResource(R.color.mycolor); buttons[i][j].setTextColor(Color.parseColor("#FFBBFF")); tab++; rowLayout.addView(buttons[i][j],param); } } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
