不知道该如何控制TextView的 TextSize 和TextView大小
用inflate 填充xml布局?
求大神指点下,为什么我获取我的控件的高设置给TextView ,TextView却比期望的大出好多
使用
MyViewFlipper myViewFlipper = (MyViewFlipper) findViewById(R.id.mvf);
myViewFlipper.setStrings(titleList);
myViewFlipper.setOnItemClickListener(new MyViewFlipper.ItemClickListener() {
@Override
public void onItemClick(int position) {
Toast.makeText(ViewFlipperActivity.this, "position" + position, Toast.LENGTH_SHORT).show();
}
});
