我想在我的Android應用只能使用Java代碼，而不是使用XML代碼動態添加布局。請幫助我。提前謝謝你。

使用此代碼，我已經做到了這一點：

公共無效makeSeat（）

{

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); 
    params.setMargins(3,3,3,3); 

    GridLayout gl = (GridLayout) findViewById(R.id.grid_main); 

    int column = 4; 
    int row = 5; 
    int i_total = 4*5; 
    int i_busSeatNo = 1; 

    gl.setAlignmentMode(GridLayout.ALIGN_BOUNDS); 
    gl.setColumnCount(column); 
    gl.setRowCount(row + 1); 

    CheckBox btn; 

    for(int i =0, c = 0, r = 1; i < i_total; i++, c++) 
    { 
     if(c == column) 
     { 
      c = 0; 
      r++; 
      i_busSeatNo++; 
     } 

     if (r == c+1){ 
      i_busSeatNo = r; 
     } 
     btn = new CheckBox(this); 
     btn.setGravity(Gravity.CENTER); 
     btn.setBackgroundResource(R.drawable.chbox); 
     btn.setButtonDrawable(R.drawable.chbox); 
     btn.setHeight(val_seat); 
     btn.setWidth(val_seat); 
     btn.setText(""+i_busSeatNo); //(r+" "+c); //r+" "+c 
     int cnt = Integer.parseInt(r+""+c); 
     btn.setId(cnt); 
     final CheckBox finalBtn = btn; 
     btn.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Toast.makeText(DynamicBus.this, 
         "id: " + finalBtn.getId() + "\nNo: " + finalBtn.getText(), 
         Toast.LENGTH_SHORT).show(); 
      } 
     }); 

     if(c != column-1) { 
      i_busSeatNo = i_busSeatNo+5; 
     } 

     gl.addView(btn, i); 

     GridLayout.LayoutParams param =new GridLayout.LayoutParams(); 
     param.height = val_seat; 
     param.width = val_seat; 
     param.rightMargin = 7; 
     param.topMargin = 7; 
     param.setGravity(Gravity.CENTER); 
     param.columnSpec = GridLayout.spec(c); 

     if (r==1) 
     param.rowSpec = GridLayout.spec(r,1); 
     btn.setLayoutParams (param); 
    } 

}
