单击一个按钮时,我正在动态创建一个按钮。即在该按钮的onClick事件下。但它是为每次单击动态创建n个按钮。
LinearLayout ll = (LinearLayout) findViewById(R.id.linearLayout1);
.....
public void onClick(View arg0) {
Button topArtistbutton = new Button(SalesPanel.this, null,android.R.attr.buttonStyleSmall);
topArtistbutton.setText("Top Artist");
topArtistbutton.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));topArtistbutton.setId(3);
ll.addView(topArtistbutton);
}
我只希望动态创建一个按钮
最佳答案
boolean bCreate = true;
...
public void onClick(View arg0) {
if (bCreate)
{
Button topArtistbutton = new Button(SalesPanel.this, null,android.R.attr.buttonStyleSmall);
topArtistbutton.setText("Top Artist");
topArtistbutton.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));topArtistbutton.setId(3);
ll.addView(topArtistbutton);
bCreate = false;
}
}
