我的应用程序中有一些图像按钮,它们显示的图像是在代码中确定的(它们不应该响应触摸/点击)。如何将图像按钮作为参数传递给android studio中的函数?我是这样做的:
private void compute_progress() {
...
progress_1();
progress_2();
...
progress_10();
...
}
private void progress_1() {
ImageButton p1 = (ImageButton) findViewById( R.id.Progress1 );
...
p1.setImageResource ( R.drawable.picture );
...
}
private void progress_2() {
ImageButton p2 = (ImageButton) findViewById( R.id.Progress2 );
...
p2.setImageResource ( R.drawable.picture );
...
}
...
private void progress_10() {
ImageButton p10 = (ImageButton) findViewById( R.id.Progress10 );
...
p10.setImageResource ( R.drawable.picture );
...
}
但我应该并且想要这样做:
private void compute_progress() {
ImageButton p1 = (ImageButton) findViewById( R.id.Progress1 );
ImageButton p2 = (ImageButton) findViewById( R.id.Progress2 );
...
ImageButton p10 = (ImageButton) findViewById( R.id.Progress10 );
...
progress("imagebutton p1");
progress("imagebutton p2");
...
progress("imagebutton p10");
...
}
private void progress("receive ImageButton p") {
...
p.setImageResource ( R.drawable.picture );
...
}

将您希望接收private void progress(ImageButton imgButton) {
imgButton.setImageResource(R.drawable.picture)
}
的方法定义为参数,如下所示:
ImageButton
然后当你需要调用你的方法时,请这样称呼它(P1是你的progress(p1)
:
{{1}}
