設定工作時間workday，gravity與layout_gravity區別
阿新 • • 發佈：2019-01-31
android:gravity 屬性是對該view中內容的限定．比如一個button 上面的text. 你可以設定該text 相對於view的靠左，靠右等位置．
android:layout_gravity是用來設定該view相對與父view 的位置．比如一個button 線上性佈局裡，你想把該button放線上性佈局裡靠左、靠右等位置就可以通過該屬性設定．
效果圖
程式碼分兩個頁面，第一個是設定頁面xml簡略如下：
<LinearLayout
android:id="@+id/att_setting_lin_workday"
android:background code：
public class AttendanceSettingActivity extends BaseActivity implements View.OnClickListener {
private LinearLayout linWorkDay;
private TextView textSettingWork;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_attendance_setting);
initView();
toListener();
}
@Override
public void initView() {
linWorkDay = (LinearLayout) findViewById(R.id.att_setting_lin_workday);
textSettingWork = (TextView) findViewById(R.id.att_setting_workday);
}
@Override
public void toListener() {
linWorkDay.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.att_setting_lin_workday:
Intent intent = new Intent();
intent.setClass(AttendanceSettingActivity.this,WorkDayActivity.class);
Bundle bundle = new Bundle();
intent.putExtras(bundle);
startActivityForResult(intent, 0);
break;
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode ==0 && resultCode == Activity.RESULT_OK){
Bundle bundle = data.getExtras();
String setWorkDay = bundle.getString("name");
textSettingWork.setText(setWorkDay);
}
}
}
