如何在Android中将两个字符串从一个活动传递到另一个活动

Question

我知道如何将一个字符串从一项活动传递到另一项活动，但是您如何对两个字符串“ nameString”和“ addressString”执行此操作？

add.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            addressString = address.getText().toString();
            nameString = name.getText().toString();
            Intent intent = new Intent(AddLocationActivity.this, MapsActivity.class);
            intent.putExtra("address", addressString);
            AddLocationActivity.this.startActivity(intent);
        }
    });

Answer 1

这样，您就可以将字符串从一个活动传递并检索到另一个活动

Intent intent = new Intent(AddLocationActivity.this, MapsActivity.class);
intent.putExtra("address", addressString);
intent.putExtra("string2", string2);
startActivity(intent);

将字符串检索到MapsActivity

Intent intent = getIntent();
String address = intent.getStringExtra("address");
String string2 intent.getStringExtra("string2");

希望它能对您有所帮助:)

Answer 2

与您传递第一个字符串的方式类似，您可以通过意图传递“ n”个字符串。

Intent intent = new Intent(AddLocationActivity.this, MapsActivity.class);
intent.putExtra("address", addressString);
intent.putExtra("string2", string2);
AddLocationActivity.this.startActivity(intent);

通过：

add.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            addressString = address.getText().toString();
            nameString = name.getText().toString();
            Intent intent = new Intent(AddLocationActivity.this, MapsActivity.class);
            intent.putExtra("name",nameString);
            intent.putExtra("address", addressString);
            AddLocationActivity.this.startActivity(intent);
        }
    });
}

要得到：

Intent intent = getIntent();
String address = intent.getStringExtra("name");
String string2 intent.getStringExtra("address");
