如何以編程方式設置按鈕layout_gravity =「fill_vertical」？

我得到了一個GridLayout，裏面有兩個或更多的按鈕，所有的按鈕都必須具有相同的寬度。我的問題是，當按鈕具有不同的文本行號時，按鈕的marginTop也會不同。我怎樣才能解決這個問題？我想要所有的按鈕在相同的高度位置。如何以編程方式設置按鈕layout_gravity =「fill_vertical」？

謝謝。

我已經嘗試設置Gravity與FILL_VERTICAL，但無法正常工作。

GridLayout grid_neighbor = (GridLayout) findViewById(R.id.grid_neighbors); 
grid_neighbor.setColumnCount(4); 
for (i = 0; i < namelist.length; ++i) { 
    Button temp = new Button(this); 
    temp.setText(namelist[i]);     

    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT); 
    lp.gravity = Gravity.FILL_VERTICAL; 
    temp.setLayoutParams(lp); 
    //temp.setGravity(Gravity.FILL_VERTICAL); 
    temp.setWidth(button_size); 
    temp.setHeight(button_size); 
    grid_neighbor.addView(temp); 
}

這裏是圖片：

現在這是工作壓力太大。

GridLayout grid_neighbor = (GridLayout) findViewById(R.id.grid_neighbors); 
grid_neighbor.setColumnCount(4); 
for (i = 0; i < namelist.length; ++i) { 
    Button temp = new Button(this); 
    temp.setText(namelist[i]);     

    RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT); 
    lp.addRule(RelativeLayout.ALIGN_TOP, temp.getId()); 
    temp.setLayoutParams(lp); 
    //temp.setGravity(Gravity.FILL_VERTICAL); 
    temp.setWidth(button_size); 
    temp.setHeight(button_size); 
    grid_neighbor.addView(temp); 
}

這將工作！謝謝。

GridLayout.Spec speccolumn = GridLayout.spec(i%4); 
GridLayout.Spec specrow = GridLayout.spec(i/4, GridLayout.TOP); 
grid_neighbor.addView(temp, new GridLayout.LayoutParams(specrow, speccolumn));

添加規則與第一個按鈕對齊頂部 – OMAK

你不能設置按鈕來填充父項的高度嗎？ – Hardik4560

@OMAK我嘗試addRule（RelativeLayout.ALIGN_TOP）＆ALIGN_PARENT_TOP，兩者都不起作用。 – JamesChiang
