Mise en page dynamique de la table sous Android?

Question

J'essaie d'ajouter une disposition de table à partir du code Java. Lorsqu'il y a deux champs dans un tablerow, il affiche uniquement le premier champ. Comment afficher la ligne entière avec tous les champs?

..... 
    .... 
    for(int idx=0;idx<4;idx++){ 
     TableRow tbrow = new TableRow(this); 

     TextView text_v1 = new TextView(this); 
     text_v1.setText("TextView"); 

     TextView text_v2 = new TextView(this); 
     text_v2.setText(" Idx : "+idx); 

     tbrow.addView(text_v1); 
     tbrow.addView(text_v2); 

     linearlayout.addView(tbrow); 
    } 
    ......... 
     ........ 

Comment faire?

Answer 1

LinearLayout ll = new LinearLayout(YourActivity.this); 
     ll.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT)); 
     ll.setBackgroundColor(Color.parseColor("#000000")); 
     ll.setOrientation(LinearLayout.VERTICAL); 

    ScrollView sv = new ScrollView(YourActivity.this); 
    sv.setSmoothScrollingEnabled(true); 

    TableLayout tl = new TableLayout(YourActivity.this); 
    tl.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT)); 
    tl.setStretchAllColumns(true); 

    TextView header= new TextView(YourActivity.this); 
    header.setText("This is heading "); 
    header.setTextColor(Color.WHITE); 
    header.setBackgroundColor(Color.parseColor("#323232")); 
    header.setTextSize(17.0f); 
    header.setGravity(Gravity.CENTER); 
    header.setClickable(true); 

    for(int sub = 0; sub <=6; sub++) { // Six Rows will be genrated. 
    TableRow tr = new TableRow(YourActivity.this); 
    tr.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT)); 
    if(sub != 0){ 
     TextView col1 = new TextView(YourActivity.this); 
     col1.setText("Column1"); 
     col1.setTextSize(17.0f); 
     col1.setPadding(5, 0, 0, 2); 
     col1.setTextColor(Color.GRAY); 
     col1.setGravity(Gravity.CENTER_VERTICAL); 
     col1.setLayoutParams(new LayoutParams(50,50)); 
     tr.addView(col1); 

     TextView col2 = new TextView(YourActivity.this); 
     col2.setText("Column2"); 
     col2.setTextSize(17.0f); 
     col2.setPadding(0, 2, 0, 2); 
     col2.setTextColor(Color.GRAY); 
     col2.setGravity(Gravity.CENTER_VERTICAL); 
     col2.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,50)); 
     tr.addView(col2); 

     View v = new View(YourActivity.this); 
     v.setBackgroundColor(Color.GRAY); 
     v.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,1)); 
     tl.addView(v); 
    } 
     tl.addView(tr);// add rows to the table. 
    } 
     TableRow row1 = new TableRow(Activity.this); // seventh row with //only one column 
     ImageButton startButton = new ImageButton(YourActivity.this); 
     startButton.setBackgroundColor(Color.TRANSPARENT); 
     startButton.setImageResource(R.drawable.icon); 
     startButton.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT)); 
     row1.addView(startButton); 




row1.setGravity(Gravity.CENTER); 
     tl.addView(row1); 

     sv.addView(tl); //add table to scrollview to make it scrollable. 
      ll.addView(header); // add heading to the LinearLayout 
      ll.addView(sv);  // add scrollview to LinearLayout 
      setContentView(ll); enter code here
