如何调整按钮数组中按钮的大小

Question

I am trying to resize the buttons in a button array I made, but I don't know how

Here's my code

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.game);
    final TableLayout container = (TableLayout) findViewById(R.id.tableLayout5);

    Button btn[][] = new Button[10][10];

    for(int i = 0; i<10; i++){
        for(int j = 0; j<10; j++){
             btn [i][j] = new Button(this);


             container.addView(btn[i][j],i);

        }

    }

}

Answer 1

I don't Know if you know, but this will create 100 buttons, anyway: it can be done like this

public void onCreate(Bundle icicle)
{
    super.onCreate(icicle);
    ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(width_of_button , height_of_button);
    final TableLayout container = (TableLayout) findViewById(R.id.tableLayout5);

    Button btn[][] = new Button[10][10];

    for(int i = 0; i<10; i++){
        for(int j = 0; j<10; j++){
            btn [i][j] = new Button(this);
            btn.setText("Button "+i+":"+j);   // if you need to trace which is which



            container.addView(btn[i][j],i,lp);// add button with specified dims

    }

If you're using the java.awt.Button class, which I'm assuming since I see no other specification here, you need to create a java.awt.Dimension object to specify the size.

Dimension size=new Dimension(4,6); //where 4 is the width and 6 is the height, although odds are you will need something much bigger

for(int i = 0; i<10; i++)
{
    for(int j = 0; j<10; j++)
    {     
         btn [i][j] = new Button(this);
         btn.setSize(size); //inherited from Component

         container.addView(btn[i][j],i);
    }
}

Change the values of the height and width as you see fit, should work. You may also need to import java.awt.Dimension

You can resize button by modified its LayoutParams, like this:

  TableLayout.LayoutParams params = new TableLayout.LayoutParams();
  params.height = 40;
  params.width = 100;
  button.setLayoutParams(params);
