我有两个适配器和另一个活动。适配器将Firebase数据结构中每个位置的额外字符串发送到下一个活动中,在该活动中显示从适配器传递来的数据。效果很好。我无法在Textview中显示数据。但是,当我打算拨打电话或发送电子邮件时,则无法使用我要使用的Extras,但是当我在Textview中设置setText时,它们显示了准确的数据。请帮助
这是适配器中的方法
@Override
public void onBindViewHolder(final MyViewHolder holder, final int position) {
database = FirebaseDatabase.getInstance();
dbreference = database.getReference("gender");
g = bookslist.get(position);
holder.teacher_quali.setText(g.getBqualifications());
holder.profile_details.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), gender_details.class);
intent.putExtra(NEAR_LOCATION, g.getBlocation());
intent.putExtra(AVAILAIBILITY, g.getBavailaile());
intent.putExtra(MOBILE, g.getSellermobile());
intent.putExtra(EMAIL, g.getSelleremail());
v.getContext().startActivity(intent);
}
});
我将MOBILE和EMAIL定义为
public static final String MOBILE = "other_mobile";
public static final String EMAIL= "other_email";
在同一适配器视图中,我的活动是
public class gender_details extends AppCompatActivity {
private TextView tutor_email,tutor_mobile;
private ImageView img;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.profile_details);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar_details); // get the reference of Toolbar
toolbar.setTitle(getIntent().getStringExtra(KEY_NAME));
toolbar.setLogo(R.drawable.ic_person_black_24dp);
setSupportActionBar(toolbar);
String tutor_email_txt = "";
String tutor_mobile_txt = "";
tutor_email_txt = intent.getStringExtra(EMAIL);
tutor_mobile_txt = intent.getStringExtra(MOBILE);
// Setting values
TextView Email_Txt = (TextView) findViewById(R.id.tutor_email);
Email_Txt.setText(tutor_email_txt);
TextView Contact_Txt = (TextView) findViewById(R.id.tutor_contact);
Contact_Txt.setText(String tutor_mobile_txt);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.toolbar_menu, menu);
return true;
}
// Activity's overrided method used to perform click events on menu items
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
// Display menu item's title by using a Toast.
if (id == R.id.action_call) {
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:"+tutor_mobile_txt));
startActivity(intent);
return true;
} else if (id == R.id.action_email) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("plain/text");
intent.putExtra(Intent.EXTRA_EMAIL, tutor_email_txt);
intent.putExtra(Intent.EXTRA_SUBJECT, "subject");
intent.putExtra(Intent.EXTRA_TEXT, "mail body");
startActivity(Intent.createChooser(intent, ""));
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onBackPressed() {
Intent intent = new Intent(gender_details.this, MainActivity.class);
startActivity(intent);
}
}
正如您在Textview中看到的那样,信息可以正确显示,但是当我习惯使用Intent Action Dail或发送电子邮件时...我无法这样做。
请帮忙
试试这个:
全局声明变量
public class gender_details extends AppCompatActivity {
private TextView tutor_email,tutor_mobile;
private ImageView img;
String tutor_email_txt;
String tutor_mobile_txt;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.profile_details);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar_details); // get the reference of Toolbar
toolbar.setTitle(getIntent().getStringExtra(KEY_NAME));
toolbar.setLogo(R.drawable.ic_person_black_24dp);
setSupportActionBar(toolbar);
tutor_email_txt = intent.getStringExtra(EMAIL);
tutor_mobilee_txt = intent.getStringExtra(MOBILE);
// Setting values
TextView Email_Txt = (TextView) findViewById(R.id.tutor_email);
Email_Txt.setText(tutor_email_txt);
TextView Contact_Txt = (TextView) findViewById(R.id.tutor_contact);
Contact_Txt.setText(String tutor_mobile_txt);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.toolbar_menu, menu);
return true;
}
// Activity's overrided method used to perform click events on menu items
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
// Display menu item's title by using a Toast.
if (id == R.id.action_call) {
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:"+tutor_mobile_txt));
startActivity(intent);
return true;
} else if (id == R.id.action_email) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("plain/text");
intent.putExtra(Intent.EXTRA_EMAIL, tutor_email_txt);
intent.putExtra(Intent.EXTRA_SUBJECT, "subject");
intent.putExtra(Intent.EXTRA_TEXT, "mail body");
startActivity(Intent.createChooser(intent, ""));
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onBackPressed() {
Intent intent = new Intent(gender_details.this, MainActivity.class);
startActivity(intent);
}
}
