Question

我正在开发一个像这个屏幕一样的UI（主屏幕）在此链接中给出了 http://www.flickr.com/photos/78431491@N07/7023063473/

- 所有信息都来自xml，这在服务器上是可用的 1-屏幕上的按钮数 2-尺寸，屏幕和按钮的背景图像，按钮上的文字以及来自的每一个服务器所以我们不能使用xml来创建layout.I已经被选中了tabbar，当我创建的按钮没有采用我使用的任何属性代码时是 -

TabHost tabHost = getTabHost();
        TabHost.TabSpec spec;
        Intent intent;
        int id = getResources().getIdentifier("com.correlation.edumationui:drawable/" + img, null, null);
        intent = new Intent().setClass(this, HomeScreen.class);//HomeScreen.class);
        Bundle objbundle = new Bundle();
        objbundle.putSerializable("screen", mscreen);
        intent.putExtras(objbundle);
        spec = tabHost.newTabSpec("title").setIndicator(title,getResources().getDrawable(id))
                      .setContent(intent);
        tabHost.addTab(spec);

用于创建按钮我正在使用此代码 - 在主屏幕Activity（HomeScreen.class）

中

LinearLayout buttonsView = new LinearLayout(this);
    buttonsView.setOrientation(LinearLayout.VERTICAL);

    for (int r = 0; r < 6; ++r)
    {
     Button btn = new Button(this);
     btn.setText("A");
     btn.setHeight(30);
     btn.setWidth(224);
     btn.setPadding(10,10,10,10);
     LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT); // Verbose!
     lp.weight = 1.0f; // This is critical. Doesn't work without it.
     buttonsView.addView(btn, lp);
    }
    ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT);
    setContentView(buttonsView, lp);

给我你宝贵的帮助....

Answer 1

而不是

  LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT); // Verbose!
 lp.weight = 1.0f; // This is critical. Doesn't work without it.
 buttonsView.addView(btn, lp);

使用

   LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(30, 224); // Verbose!
   lp.weight = 1.0f; // This is critical. Doesn't work without it.
   buttonsView.addView(btn,lp);

反映布局参数中按钮的宽度和高度。

Answer 2

使用LayoutParameters设置按钮的宽度，高度和边距。

Answer 3

尝试使用setLayoutParams将高度，宽度和填充设置为：

Button btn = new Button (this);
LayoutParams  params = Prams // Set Params Which you want to set for your view.
btn.setLayoutPrams(params);

希望这会对你有所帮助。

Answer 4

以编程方式设置高度和宽度，您可以使用如下所示的set layoutparams。

LinearLayout ly = (LinearLayout) findViewById(R.id.verify);
 Button buyButton = new Button(this);
        buyButton.setText("button");
        buyButton.setLayoutParams(new LayoutParams(50,
        50));
        buyButton.setPadding(10, 10, 10, 10);
        ly.addView(buyButton);

按钮是不是取其属性？
