我正在使用视图寻呼机和两个布局,每个布局都有一个按钮。我想以圆圈形式显示这些按钮。截至目前,我只是长方形。以下是我的代码。
rounded_cell.xml
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android" >
<shape android:shape="rectangle" >
<gradient
android:angle="0"
android:endColor="@android:color/white"
android:startColor="@android:color/white" />
<corners
android:bottomLeftRadius="10dp"
android:bottomRightRadius="10dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp" />
<stroke
android:width="1dp"
android:color="@android:color/holo_blue_dark" />
</shape>
MainActivity.java
package com.circleviewpager;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.support.v4.view.ViewPager.OnPageChangeListener;
import android.widget.Button;
public class MainActivity extends FragmentActivity {
private ViewPager _mViewPager;
private ViewPagerAdapter _adapter;
private Button _btn1, _btn2;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setUpView();
setTab();
}
private void setUpView() {
_mViewPager = (ViewPager) findViewById(R.id.viewPager);
_adapter = new ViewPagerAdapter(getApplicationContext(),
getSupportFragmentManager());
_mViewPager.setAdapter(_adapter);
_mViewPager.setCurrentItem(0);
initButton();
}
private void setTab() {
_mViewPager.setOnPageChangeListener(new OnPageChangeListener() {
@Override
public void onPageScrollStateChanged(int position) {
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
@Override
public void onPageSelected(int position) {
// TODO Auto-generated method stub
btnAction(position);
}
});
}
private void btnAction(int action) {
switch (action) {
case 0:
setButton(_btn1, "1", 20, 20);
setButton(_btn2, "", 20, 20);
break;
case 1:
setButton(_btn2, "2", 20, 20);
setButton(_btn1, "", 20, 20);
break;
}
}
private void initButton() {
_btn1 = (Button) findViewById(R.id.btn1);
_btn2 = (Button) findViewById(R.id.btn2);
setButton(_btn1, "1", 20, 20);
setButton(_btn2, "", 20, 20);
}
private void setButton(Button btn, String text, int h, int w) {
btn.setWidth(w);
btn.setHeight(h);
btn.setText(text);
}
}
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
