我創建了Segmented RadioButtons，它的工作正常。我創建了它Statically，現在我想創建相同的按鈕Dynamically，我試過了，它不工作。
創建的StaticSegmented RadioButtons看起來如下：
動態創建分段單選按鈕
我想是這樣如下：
我想如下：
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#BCC6CC" >
<com.sushi19.myProj.segmented.SegmentedRadioGroup
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dip"
android:layout_gravity="center_horizontal"
android:orientation="horizontal"
android:id="@+id/segment1"
android:checkedButton="@+id/btn1" >
<RadioButton
android:id="@+id/btn1"
android:layout_width="100dp"

android:minHeight="33dip"
android:minWidth="40dip"
android:text="@string/segmentedRadio1"
android:textAppearance="@dimen/text_size"
android:textColor="@drawable/radio_text_color" />
<RadioButton

SegmentedRadioGroup類作爲：
package com.sushi19.myProj.segmented;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.RadioGroup;
public class SegmentedRadioGroup extends RadioGroup {
public SegmentedRadioGroup(Context context) {
super(context);
}
public SegmentedRadioGroup(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
protected void onFinishInflate() {
super.onFinishInflate();
changeButtonsImages();
}
private void changeButtonsImages(){
int count = super.getChildCount();
if(count > 1){
super.getChildAt(0).setBackgroundResource(com.sushi19.myProj.R.drawable.segment_radio_left);
for(int i=1; i < count-1; i++){
super.getChildAt(i).setBackgroundResource(com.sushi19.myProj.R.drawable.segment_radio_middle);
}
super.getChildAt(count-1).setBackgroundResource(com.sushi19.myProj.R.drawable.segment_radio_right);
}else if (count == 1){
super.getChildAt(0).setBackgroundResource(com.sushi19.myProj.R.drawable.segment_button);
}
}
}
在GameBoardActivity類
package com.sushi19.myProj;
import com.sushi19.myProj.segmented.SegmentedRadioGroup;
import android.os.Bundle;
import android.annotation.SuppressLint;
import android.app.ActionBar.LayoutParams;
import android.app.Activity;
import android.graphics.Color;
import android.util.TypedValue;
import android.view.Gravity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.RadioButton;
public class GameBoardActivity extends Activity {
RadioButton rb;
SegmentedRadioGroup srg;
@SuppressLint({ "NewApi", "InlinedApi", "ResourceAsColor" })
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.game_board);
srg = (SegmentedRadioGroup)findViewById(R.id.segment_buttons);
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
for(int i=0; i<15; i++){
rb = new RadioButton(this);
rb.setId(i);
rb.setGravity(Gravity.CENTER);
//convert pixels to dip
int height = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 33, getResources().getDisplayMetrics());
int width = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 40, getResources().getDisplayMetrics());
rb.setMinHeight(height);
rb.setMinWidth(width);
rb.setText("Button"+i);
rb.setButtonDrawable(null);
rb.setTextSize(getResources().getDimension(R.dimen.text_size));
rb.setTextColor(R.drawable.radio_text_color);
rb.setLayoutParams(params);
srg.addView(rb);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.game_board, menu);
return true;
}
}
我得到的輸出如下：
I want output as I mentioned above.. Where and what I'm doing mistakes...
