我开发了一个没有的屏幕。来自数据库的人员显示在列表视图中。我想显示所选人员的个人资料页面。所以我的问题是如何将所选人员的每个细节（如姓名，联系方式等）绑定到我创建的个人资料页面？我是否必须在onItemClickListener中调用getById API？
以下是已修改代码： -
public class Test extends AppCompatActivity {
List<Genie> genieList;
GenieAdapter genieAdapter;
TextView responseView;
ProgressBar progressBar;
Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
responseView = (TextView) findViewById(R.id.responseView);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
button = (Button) findViewById(R.id.test);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(Test.this, "Blahblah", Toast.LENGTH_LONG).show();
new RetrieveFeedTask().execute();
}
});
}
class RetrieveFeedTask extends AsyncTask<Void, Void, List<Genie>> {
private Exception exception;
protected void onPreExecute() {
progressBar.setVisibility(View.VISIBLE);
responseView.setText("");
}
protected List<Genie> doInBackground(Void... urls) {
GenieService genieService = new GenieService();
return genieService.getAll();
}
protected void onPostExecute(List<Genie> genies) {
if (genies == null) {
new ArrayList<Genie>(); // "THERE WAS AN ERROR"
} else {
progressBar.setVisibility(View.GONE);
Log.i("INFO", genies.get(0).name);
List<String> rows = genies.stream().map(genie -> getRow(genie)).collect(Collectors.toList());
genieAdapter=new GenieAdapter(getApplicationContext(),R.layout.genie_list, genies);
ListView list=(ListView)findViewById(R.id.listViewMain);
list.setAdapter(genieAdapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(Test.this, "" + position, Toast.LENGTH_SHORT).show();
// if (position == 1) {
// startActivity(new Intent(Test.this, viewGenie1.class));
// }
}
});
list.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent(Test.this, viewGenie1.class);
intent.putExtra("name", "%s");
intent.putExtra("add", "%s");
intent.putExtra("phn", "%s");
intent.putExtra("sal", "%s");
intent.putExtra("lea", "%s");
startActivity(intent);
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
}
}
private String getRow(Genie g) {
return String.format("%s, %s, %s, %s, %s", g.name, g.salary, g.contact, g.paid_leaves, g.address);
}
}
}
这里是viewGenie1.class： -
public class viewGenie1 extends AppCompatActivity implements View.OnClickListener {
TextView name;
EditText address, contact, salary, leaves;
Button attendance;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view_genie1);
name = (TextView) findViewById(R.id.txName);
address = (EditText) findViewById(R.id.txAddress);
contact = (EditText) findViewById(R.id.txContact);
salary = (EditText) findViewById(R.id.txSalary);
leaves = (EditText) findViewById(R.id.txLeaves);
Button update=(Button)findViewById(R.id.btUpdate);
update.setOnClickListener(this);
Button delete=(Button)findViewById(R.id.delete);
delete.setOnClickListener(this);
Button attendance = (Button) findViewById(R.id.attendance);
attendance.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showAtt();
}
});
String value = "";
if (getIntent().hasExtra("name")) {
String name = getIntent().getExtras().getString("name");
String add = getIntent().getExtras().getString("add");
String phn = getIntent().getExtras().getString("phn");
String sal = getIntent().getExtras().getString("sal");
String lea = getIntent().getExtras().getString("lea");
}
name.setText(value);
address.setText(value);
contact.setText(value);
salary.setText(value);
leaves.setText(value);
}
@Override
public void onClick(View view) {
final AlertDialog.Builder builder=new AlertDialog.Builder(viewGenie1.this);
builder.setMessage("Are you sure you want to delete records?");
builder.setCancelable(true);
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
new deleteTask().execute();
Toast.makeText(viewGenie1.this, "Genie deleted..!", Toast.LENGTH_SHORT).show();
startActivity(new Intent(viewGenie1.this, navDrawer.class));
// GenieService genieService=new GenieService();
// genieService.delete(2);
// Log.d("Information", String.valueOf(genieService.delete(2)));
// Log.i("INFO", genies.get(0).name);
// startActivity(new Intent(viewGenie1.this,Test.class));
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert=builder.create();
alert.show();
}
private class deleteTask extends AsyncTask {
@Override
protected Object doInBackground(Object[] objects) {
GenieService genieService = new GenieService();
return genieService.delete(6);
}
}
public void showAtt() {
Intent intent = new Intent(this, viewAbsentee.class);
startActivity(intent);
}
}
这是我使用硬编码值创建的配置文件页面的xml文件，但希望使用以下方法显示本地mysql数据库中的实际值 API调用： -

我想在个人资料页面中显示详细信息，如下所示： -
答案 0 :(得分：0)
请使用select ID from table_1 t1 where (UNIX_TIMESTAMP(t1.Date2)-UNIX_TIMESTAMP(t1.Date1)>864000)
putExtra()在viewGenie1类中，你可以得到像这样的值
Intent intent = new Intent(Test.this, viewGenie1.class);
intent.putExtra("key","Value"); //Key must be unique and value should be the value which you want to pass to viewGenie1 class.
startActivity(intent);
请替换
String value="";
if(getIntent().hasExtra("key")) {
value = getIntent().getExtras().getString("key");
}
到
String value = "";
if (getIntent().hasExtra("name")) {
String name = getIntent().getExtras().getString("name");
String add = getIntent().getExtras().getString("add");
String phn = getIntent().getExtras().getString("phn");
String sal = getIntent().getExtras().getString("sal");
String lea = getIntent().getExtras().getString("lea");
}
name.setText(value);
address.setText(value);
contact.setText(value);
salary.setText(value);
leaves.setText(value);
