在桌面布局中对齐imageview

Question

这应该很容易，我该如何对齐中间的星星。我在代码中动态添加顶部标题文字视图和星星。我试图在imageview上设置引力不起作用。

更新：我添加iv.setScaleType(ImageView.ScaleType.FIT_START)现在明星对齐到左

Answer 1

你应该这样做：

TableRow.LayoutParams params = new TableRow.LayoutParams(0,WRAP_CONTENT); 

你应该有textview的布局参数textviews。

然后在这个参数中，你应该增加重量。

params.weight = 1; 
params.gravity = GRAVITY.CENTER; 

，你的表行应该有重力“中心”，其内容（不布置重力）。

试着这样做：

for (Games game : Games.values()) { 
       TableRow newRow = new TableRow(this); 
       newRow.setLayoutParams(tableRowParams); 

TableRow.LayoutParams params2 = new TableRow.LayoutParams(0, TableRow.LayoutParams.WRAP_CONTENT); 

       params2.weight = .8f; 
       params2.gravity= Gravity.CENTER; 

       String[] words = game.name().split("(?=[A-Z])"); 
       String name = ""; 
       for (String word : words) { 
        if(word.length() < 1) continue; 
        name += word + "\n"; 
       } 

       tv = new TextView(this); 
       tv.setTextSize(fontSize); 
       tv.setText(name); 
       tv.setLayoutParams(params2); 
       newRow.addView(tv); 
       newRow.setWeightSum(6); 

       for (Level level : Level.values()) { 
        ImageView iv = new ImageView(this); 

        iv.setScaleType(ImageView.ScaleType.CENTER_INSIDE); 
        iv.setAdjustViewBounds(true); 
        iv.setLayoutParams(params); 

        tv = new TextView(this); 
        tv.setLayoutParams(params); 
        tv.setText("EASY"); 
        tv.setTextSize(fontSize); 

        if(acheivements.getPassed(level, game))//has achievement 
        { 
         iv.setImageResource(R.drawable.star_gold_full_small); 
        } 
        else { 
         iv.setImageResource(R.drawable.star_gold_empty_small); 
        } 
        newRow.addView(tv); 
       } 
       tbLayout.addView(newRow); 
      } 

在此代码，我因为TextView中使用的1重量让您的图象是小右胸创造了新的布局PARAMS为params2。我已经使用了.8f的重量名称，所以现在它的工作正常。按照你的要求做。 希望它有助于！
