如何让edittext在activity起始的时候不自动获得焦点

Answer 1

在进入一个Activity时，如果这个Activity中有EditText，则这个EditText会自动获取焦点，然后就会弹出软键盘，这样给用户体验不是很好。所以一般会通过代码控制让EditText不获取焦点。常用的方式如下，在Activity的布局文件中加上如下代码：
<!-- 输入焦点控制 -->

<LinearLayout
android:layout_width="0px"
android:layout_height="0px"
android:focusable="true"
android:focusableInTouchMode="true" />
在日前开发的一个项目中界面中除了EditText就是Spinner 和Button等空间，EditText 获取焦点以后，点击Spinner总是无法移除焦点：采取如下方式解决，
当点击Spinner时让EditText失去焦点即可：（见标红代码）
// 初始化两个LayoutInflater对象
inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
layoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

et_name = (EditText) findViewById(R.id.et_name);
ib_add = (ImageButton) findViewById(R.id.ib_add);
ib_clear = (Button) findViewById(R.id.ib_clear);
ib_query = (Button) findViewById(R.id.ib_query);
ib_down = (Button) findViewById(R.id.ib_down);
ib_save = (Button) findViewById(R.id.ib_save);
ib_back = (ImageButton) findViewById(R.id.ib_back);
// ib_sex = (ImageButton) findViewById(R.id.ib_sex) ;

ib_add.setOnClickListener(this);
ib_clear.setOnClickListener(this);
ib_query.setOnClickListener(this);
ib_down.setOnClickListener(this);
ib_save.setOnClickListener(this);
ib_back.setOnClickListener(this);
// ib_sex.setOnClickListener(this) ;

// 性别
ArrayAdapter<String> sexAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item);

int position = 0;
for (int i = 0; i < sexList.length; i++) {
sexString = sexList[i];
sexAdapter.add(sexString);
}
sp_sex = (Spinner) findViewById(R.id.sp_sex);
sp_sex.setAdapter(sexAdapter);
sp_sex.setFocusable(true);
sp_sex.setSelection(position);
sp_sex.setOnTouchListener(new OnTouchListener() {

if (v1 != null)
v1.setTextColor(Color.BLACK); // 可以随意设置自己要的颜色值
