我想实现以下方法:
public void setButtons(Button b, int h, int w){
b.setLayoutParams(new LinearLayout.LayoutParams(w, h));
}
在我的 onCreate 方法中:
for (int i = 0; i < buttons.length; i++){
public void setButtons(buttons[i], widthOfButtons, widthOfButtons);
}
但是我遇到了错误,我已经尝试找出问题所在一段时间了,但是我对java相当陌生,我觉得这段代码只需要别人的眼睛,所以有人可以告诉我如何正确实现上述方法吗?谢谢。

添加更多代码: 下面是我初始化数组的地方:
Button[] buttons = new Button[23];
buttons[0] = (Button) findViewById(R.id.alef);
buttons[1] = (Button) findViewById(R.id.beis);
buttons[3] = (Button) findViewById(R.id.gimmel);
buttons[4] = (Button) findViewById(R.id.daled);
buttons[5] = (Button) findViewById(R.id.heh);
buttons[6] = (Button) findViewById(R.id.vav);
buttons[7] = (Button) findViewById(R.id.zayin);
buttons[7] = (Button) findViewById(R.id.ches);
buttons[8] = (Button) findViewById(R.id.tes);
buttons[9] = (Button) findViewById(R.id.yud);
buttons[10] = (Button) findViewById(R.id.chaf);
buttons[11] = (Button) findViewById(R.id.lamed);
buttons[12] = (Button) findViewById(R.id.mem);
buttons[13] = (Button) findViewById(R.id.nun);
buttons[14] = (Button) findViewById(R.id.ayin);
buttons[15] = (Button) findViewById(R.id.peh);
buttons[16] = (Button) findViewById(R.id.tzadi);
buttons[17] = (Button) findViewById(R.id.kuf);
buttons[18] = (Button) findViewById(R.id.reish);
buttons[19] = (Button) findViewById(R.id.shin);
buttons[20] = (Button) findViewById(R.id.taf);
buttons[21] = (Button) findViewById(R.id.empty1);
buttons[22] = (Button) findViewById(R.id.empty2);
buttons[23] = (Button) findViewById(R.id.empty3);
这是我声明方法的完整类:
import android.widget.Button;
import android.widget.LinearLayout;
public class initButtons {
public void setButtons(Button b, int h, int w){
b.setLayoutParams(new LinearLayout.LayoutParams(w, h));
}
}
最佳答案
替换 onCreate 中的以下行
public void setButtons(buttons[i], widthOfButtons, widthOfButtons);
由
new initButtons().setButtons(buttons[i], widthOfButtons, widthOfButtons);
或通过
initButtons iButton = new initButtons();
iButton.setButtons(buttons[i], widthOfButtons, widthOfButtons);
