androidbutton屬性

A. Android RadioButton控制項怎麼設置圖片（屬性）android:（drawable）

我覺得RadioButton原始的button如果設置為 android:button="@null「 而用android：drowableLeft=」@drawable/radiobtn_selector「；這樣顯示圖片的話效果會更加好，而且可以用android：drawablePading=」10dp「這個屬性控制圖片和字兒的距離。 希望可以幫到你。Thanks

B. 如何自定義android Button樣式

在windows7操作系統Android studio中按照如下方法定義button的樣式。

1、首先使用Android studio創建一個項目，項目結構如下：

C. android 如何設置button的大小

在相對應的layout.xml文件中，button下可以定義android:layout_width和android:layout_height兩個屬性可以用來控制button的大小，希望可以幫助到你！

D. android中button有幾種狀態

Android中，button按鈕通常有三個狀態：

1. normal(正常狀態);
2. focus(焦點狀態);
3. pressed(按下狀態)
4. selected(選中狀態)

注意：按下後未松開前是pressed，表示按下。
松開後當前項目獲得焦點，是focused。
focused的項只有一個，selected是當選中該按鈕時顯示的狀態

F. android 的Button怎樣自動觸發按下的動作

android 的Button自動觸發按下的動作需要在Button添加android:onClick="click"屬性，click為方法名，使用步驟如下：

1、使用Android studio創建一個Android項目並打開布局文件，在布局文件中添加一個Button，並設置android:onClick="click"，如下圖：

G. 如何自定義android Button樣式

親，可以用到Drawable中的shape哦，給你一個demo

java"><?xmlversion="1.0"encoding="utf-8"?>
<selectorxmlns:android="

<itemandroid:state_focused="false">
<shape>
<solidandroid:color="@color/find_passwordbar_bg"/>
<strokeandroid:width="0.5dp"android:color="#C8C8C8"/>
</shape>
</item>

<itemandroid:state_focused="true">
<shape>
<solidandroid:color="@color/find_passwordbar_bg"/>
<strokeandroid:width="0.5dp"android:color="@color/main_color"/>
</shape>
</item>

</selector>

各個屬性的介紹

solid：實心，就是填充的意思
android:color指定填充的顏色

gradient：漸變
android:startColor和android:endColor分別為起始和結束顏色，ndroid:angle是漸變角度，必須為45的整數倍。
另外漸變默認的模式為android:type="linear"，即線性漸變，可以指定漸變為徑向漸變，android:type="radial"，徑向漸變需要指定半徑android:gradientRadius="50"。

stroke：描邊
android:width="2dp"描邊的寬度，android:color描邊的顏色。
我們還可以把描邊弄成虛線的形式，設置方式為：
android:dashWidth="5dp"
android:dashGap="3dp"
其中android:dashWidth表示'-'這樣一個橫線的寬度，android:dashGap表示之間隔開的距離。

corners：圓角
android:radius為角的弧度，值越大角越圓。
我們還可以把四個角設定成不同的角度，方法為：
<corners
android:topRightRadius="20dp"右上角
android:bottomLeftRadius="20dp"右下角
android:topLeftRadius="1dp"左上角
android:bottomRightRadius="0dp"左下角
/>

我自己寫的一個按鈕，效果就像圖中所示，用的Shape

新建後存放位置在res/drawable下

希望能幫到你，還望採納

H. android按鈕隱藏屬性

設置android:visibility="gone"

在Android開發中，大部分控制項都有visibility這個屬性，其屬性有3個分別為「visible 」、「invisible」、「gone」。主要用來設置控制控制項的顯示和隱藏。
visible ：可見
invisible：不可見，但是當前view佔位（即顯示空白）
gone：不可見（隱藏，不顯示空白）

I. 求 android RadioButton屬性詳解

一： 單選按鈕RadioButton在Android平台上也應用的非常多，比如一些選擇項的時候，會用到單選按鈕，實現單選按鈕由兩部分組成，也就是RadioButton和RadioGroup配合使用

RadioButton的單選按鈕;

RadioGroup是單選組合框，用於將RadioButton框起來；

在沒有RadioGroup的情況下，RadioButton可以全部都選中；

當多個RadioButton被RadioGroup包含的情況下，RadioButton只可以選擇一個；

注意：單選按鈕的事件監聽用setOnCheckedChangeListener來對單選按鈕進行監聽

例子：一道選擇題，選擇哪個城市美女最多，當然，這個就是為了測試

Java代碼
1.package org.loulijun.radio;
2.
3.import android.app.Activity;
4.import android.os.Bundle;
5.import android.view.Gravity;
6.import android.widget.RadioButton;
7.import android.widget.RadioGroup;
8.import android.widget.TextView;
9.import android.widget.Toast;
10.
11.public class RadioTest extends Activity {
12. /** Called when the activity is first created. */
13. TextView textview;
14. RadioGroup radiogroup;
15. RadioButton radio1,radio2,radio3,radio4;
16. @Override
17. public void onCreate(Bundle savedInstanceState) {
18. super.onCreate(savedInstanceState);
19. setContentView(R.layout.main);
20. textview=(TextView)findViewById(R.id.textview1);
21. radiogroup=(RadioGroup)findViewById(R.id.radiogroup1);
22. radio1=(RadioButton)findViewById(R.id.radiobutton1);
23. radio2=(RadioButton)findViewById(R.id.radiobutton2);
24. radio3=(RadioButton)findViewById(R.id.radiobutton3);

26.
27. radiogroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
28.
29. @Override
30. public void onCheckedChanged(RadioGroup group, int checkedId) {
31. // TODO Auto-generated method stub
32. if(checkedId==radio2.getId())
33. {
34. DisplayToast("正確答案："+radio2.getText()+"，恭喜你，回答正確！");
35. }else
36. {
37. DisplayToast("請注意，回答錯誤！");
38. }
39. }
40. });
41. }
42. public void DisplayToast(String str)
43. {
44. Toast toast=Toast.makeText(this, str, Toast.LENGTH_LONG);
45. toast.setGravity(Gravity.TOP,0,220);
46. toast.show();
47. }
48.}

strings.xml文件

Xml代碼
1.<?xml version="1.0" encoding="utf-8"?>
2.<resources>
3. <string name="hello">哪個城市美女多？</string>
4. <string name="app_name">單選按鈕測試</string>
5. <string name="radiobutton1">杭州</string>
6. <string name="radiobutton2">成都</string>
7. <string name="radiobutton3">重慶</string>
8. <string name="radiobutton4">蘇州</string>
9.</resources>

main.xml文件：注意，這裡面，4個RadioButton包含在RadioGroup中

Xml代碼
1.<?xml version="1.0" encoding="utf-8"?>
2.<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
3. android:orientation="vertical"
4. android:layout_width="fill_parent"
5. android:layout_height="fill_parent"
6. >
7.<TextView
8. android:layout_width="fill_parent"
9. android:layout_height="wrap_content"
10. android:text="@string/hello"
11. android:id="@+id/textview1"
12. />
13. <RadioGroup
14. android:id="@+id/radiogroup1"
15. android:layout_width="wrap_content"
16. android:layout_height="wrap_content"
17. android:orientation="vertical"
18. android:layout_x="3px"
19. >
20. <RadioButton
21. android:id="@+id/radiobutton1"
22. android:layout_width="wrap_content"
23. android:layout_height="wrap_content"
24. android:text="@string/radiobutton1"
25. />
26. <RadioButton
27. android:id="@+id/radiobutton2"
28. android:layout_width="wrap_content"
29. android:layout_height="wrap_content"
30. android:text="@string/radiobutton2"
31. />
32. <RadioButton
33. android:id="@+id/radiobutton3"
34. android:layout_width="wrap_content"
35. android:layout_height="wrap_content"
36. android:text="@string/radiobutton3"
37. />
38. <RadioButton
39. android:id="@+id/radiobutton4"
40. android:layout_width="wrap_content"
41. android:layout_height="wrap_content"
42. android:text="@string/radiobutton4"
43. />
44. </RadioGroup>
45.</LinearLayout>

二：Android 自定義RadioButton的樣式（和上面關系不大）

我們知道Android控制項里的button，listview可以用xml的樣式自定義成自己希望的漂亮樣式。

最近用到RadioButton，利用xml修改android:background="@drawable/button_drawable"，其中button_drawable為自己定義的.xml文件（res/drawable文件下），但是不成功，到網上查找，也沒有正確的說法，我就開始自己嘗試，最後做好了。

其實方法很簡單，同樣在res/drawable新建radiobutton.xml如下

Xml代碼
1.<selector xmlns:android="http://schemas.android.com/apk/res/android">
2.
3. <item
4.
5.
6. android:state_enabled="true"
7.
8. android:state_checked="true"
9.
10. android:drawable="@drawable/check" />
11.
12. <item
13.
14. android:state_enabled="true"
15.
16. android:state_checked="false"
17.
18. android:drawable="@drawable/checknull" />
19.
20. </selector>
check和checknull分別為選中和位選中的圖片。
然後在你的布局文件中，RadioButton 布局
設置android:button = "@drawable/radiobutton"，就可以了！
