我对imagebutton数组有疑问。我想通过在RelativeLayout中更改marginTop和marginLeft,以编程方式将数组的每个图像按钮放在不同的位置。这是我的代码,但它只显示同一位置上的所有图像按钮,就像它们没有边距一样:
DatabaseHandler db;
db= new DatabaseHandler(this);
int databasereadercount=db.getMemoryCount();
ImageButton[] button= new ImageButton[60];
setContentView(R.layout.playsolo);
RelativeLayout layout = (RelativeLayout) findViewById(R.id.playsololayout);
for(int i=0;i<60;i++){
if(i<=databasereadercount){
button[i]=new ImageButton(this);
FrameLayout.LayoutParams[] params = new FrameLayout.LayoutParams[60];
params[i]=new FrameLayout.LayoutParams(100,100);
params[i].setMargins(10*i, 5*i, 0, 0); //for example
Bitmap bitmap=BitmapFactory.decodeResource(getResources(),R.drawable.raster);
bitmap=Bitmap.createScaledBitmap(bitmap, 480, 320, true);
Drawable drawable = new BitmapDrawable(getResources(),bitmap);
StateListDrawable states = new StateListDrawable();
states.addState(new int[] {android.R.attr.state_pressed},drawable);
states.addState(new int[] {android.R.attr.state_focused},drawable);
states.addState(new int[] { },drawable);
button[i].setImageDrawable(states);
button[i].setId(i);
button[i].setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
// TODO Auto-generated method stub
startlevel(v.getId());
}
});
layout.addView(button[i],params[i]);
}
}

当您的布局为FrameLayout.LayoutParams
时,您正在使用RelativeLayout
。如果我没有完全弄错,你应该使用RelativeLayout.LayoutParams
代替。
