Spinner值的獲取和設置默認值

	//設置Spinner樣式android.R.layout.simple_spinner_item，綁定數組數據array，將數組內容和ArrayAdapter連接
		ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
				android.R.layout.simple_spinner_item, array);
		adapter
				.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
		mSpinner.setAdapter(adapter);
		//設置默認選中
		mSpinner.setSelection(2,true);
		//添加監聽事件
		mSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {

			@Override
			public void onItemSelected(AdapterView<?> adapterView, View view,
					int position, long id) {
				//獲取選中值
				Spinner spinner = (Spinner) adapterView;
				String data = (String) spinner.getItemAtPosition(position);
			}

			@Override
			public void onNothingSelected(AdapterView<?> arg0) {
				// TODO Auto-generated method stub

			}
		});

二. Spinner的數據綁定方式

1、 通過數組字符串綁定

   

private static final String[] m_Countries = { "111", "222", "333", "444", "555" };   //定義數組

   public String[]  petArray = new String[] { "狗", "貓", "其他" };

    使用方法如上例

2、通過資源文件配置：比如values文件夾中的：arrays.xml、colors.xml、ids.xml、strings.xml、styles.xml等等

<string-array name="debitCardNumber">
        <item>信用卡111</item>
        <item>信用卡222</item>
        <item>信用卡333</item>
        <item>信用卡444</item>
        <item>信用卡555</item>
    </string-array>

　　綁定方法：

 // 准備一個數組適配器  
        // R.array.colors : 直接從strings.xml去數據  
        // android.R.layout.simple_spinner_item ： 設置Spinner樣式（無下拉列表時）  
        ArrayAdapter<CharSequence> arrayAdapter = ArrayAdapter  
                .createFromResource(this, R.array.colors,  
                        android.R.layout.simple_spinner_item);  
        // 設置下拉列表樣式  
        arrayAdapter  
                .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);  
        // 為下拉列表設置適配器  
        spinner.setAdapter(arrayAdapter);  
        // 為下拉列表綁定事件監聽器  
        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {  
  
            @Override  
            public void onItemSelected(AdapterView<?> parent, View view,  
                    int position, long id) {  
                Toast.makeText(  
                        SpinnerDemoActivity.this,  
                        "選擇的色彩： "  
                                + parent.getItemAtPosition(position).toString(),  
                        Toast.LENGTH_LONG).show();  
            }  
  
            @Override  
            public void onNothingSelected(AdapterView<?> parent) {  
  
            }  
        });  

　　3、數據庫存儲

三、 Spinner實現省市二級聯動

ArrayAdapter<String> adapterProvince = new ArrayAdapter<String>(
				this,
				android.R.layout.simple_spinner_item, provinceArray);
		adapterProvince
				.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
		mSpinnerProvince.setAdapter(adapterProvince);
//		mSpinnerProvince.setSelection(2,true);//設置默認選中
		mSpinnerProvince
				.setOnItemSelectedListener(new OnItemSelectedListener() {

					@Override
					public void onItemSelected(AdapterView<?> adapterView,
							View view, int position, long id) {
						Spinner spinner = (Spinner) adapterView;
						String pro = (String) spinner
								.getItemAtPosition(position);
						mUserProvince = pro;

						ArrayAdapter<String> adapter = new ArrayAdapter<String>(
								this,
								android.R.layout.simple_spinner_item, city);
						adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
						mSpinnerCity.setAdapter(adapter);
						mSpinnerCity
								.setOnItemSelectedListener(new OnItemSelectedListener() {

									@Override
									public void onItemSelected(
											AdapterView<?> adapterView,
											View view, int position, long id) {
										Spinner spinner = (Spinner) adapterView;
										String pro = (String) spinner
												.getItemAtPosition(position);
										mUserCity = pro;
										Log.v("city", "mUserProvince:"
												+ mUserProvince
												+ "   mUserCity:" + mUserCity);
									}

									@Override
									public void onNothingSelected(
											AdapterView<?> arg0) {
										// TODO Auto-generated method stub

									}

								});
					}

　　直接用string設置默認選中的方法：

int pos=adapter.getPosition(str);

mSpinnerCity.setSelection(pos);
