以編程方式安裝TableLayout

Question

我學會了如何使用XML文件創建UI。但請幫助我瞭解如何以編程方式執行此操作，而不使用XML文件，特別是對於LinearLayout以外的其他用戶。

Answer 1

使用下面的代碼來創建TableLayout

TableLayout tbl=new TableLayout(context); 

使用下面創建錶行

TableRow tr=new TableRow(context); 

添加視圖到錶行

tr.addView(view); 

查看這裏可能是一個TextView或EditText上或等..

添加錶行到TableLayout

tbl.addView(tr); 

就像你可以添加更多的錶行到表佈局。

下面的代碼示例給出Here。

public class tablelayout extends Activity implements OnClickListener { 
/** Called when the activity is first created. */ 

//initialize a button and a counter 
Button btn; 
int counter = 0; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    // setup the layout 
    setContentView(R.layout.main); 

    // add a click-listener on the button 
    btn = (Button) findViewById(R.id.Button01); 
    btn.setOnClickListener(this);   

} 

// run when the button is clicked 
public void onClick(View view) { 

    // get a reference for the TableLayout 
    TableLayout table = (TableLayout) findViewById(R.id.TableLayout01); 

    // create a new TableRow 
    TableRow row = new TableRow(this); 

    // count the counter up by one 
    counter++; 

    // create a new TextView 
    TextView t = new TextView(this); 
    // set the text to "text xx" 
    t.setText("text " + counter); 

    // create a CheckBox 
    CheckBox c = new CheckBox(this); 

    // add the TextView and the CheckBox to the new TableRow 
    row.addView(t); 
    row.addView(c); 

    // add the TableRow to the TableLayout 
    table.addView(row,new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); 

} 

}

| * |表佈局使用Java代碼3×3個按鈕：在tblRowCwtVal在tblColCwtVal
設置字符串
列的 集數排

集數|在tblAryVar中繪製

在這個例子中，我們使用了每個表格視圖的按鈕。您可以使用TextView | ImageView的和修改相應

int tblRowCwtVal = 3; 
int tblColCwtVal = 3; 
int[][] tblAryVar = 
    { 
     {R.drawable.ic_name, R.drawable.ic_name, R.drawable.ic_name}, 
     {R.drawable.ic_name, R.drawable.ic_name, R.drawable.ic_name}, 
     {R.drawable.ic_name, R.drawable.ic_name, R.drawable.ic_name} 
    }; 

@Override 
protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.srn_nam_uic); 

    namRelLyoVar = (RelativeLayout) findViewById(R.id.NamSrnLyoUid); 

    TableLayout namTblLyoVar = new TableLayout(this); 
    TableLayout.LayoutParams tblLyoRulVar = new TableLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT); 
    TableRow.LayoutParams btnLyoRulVar = new TableRow.LayoutParams(50,50); 

    for(int tblRowIdxVar = 0; tblRowIdxVar < tblRowCwtVal; tblRowIdxVar++) 
    { 
     TableRow tblRowVar = new TableRow(this); 

     for(int tblColIdxVar = 0; tblColIdxVar < tblColCwtVal; tblColIdxVar++) 
     { 
      Button namIdxBtnVar = new Button(this); 
      Drawable DrwablIdxVar = getResources().getDrawable(tblAryVar[tblRowIdxVar][tblColIdxVar]); 
      DrwablIdxVar.setColorFilter(Color.rgb(0,128,0), PorterDuff.Mode.SRC_IN); 
      namIdxBtnVar.setBackground(DrwablIdxVar); 

      tblRowVar.addView(namIdxBtnVar, btnLyoRulVar); 
     } 
     namTblLyoVar.addView(tblRowVar, tblLyoRulVar); 
    } 

    namTblLyoVar.setLayoutParams(tblLyoRulVar); 
    namRelLyoVar.addView(namTblLyoVar); 
}
