Question

我有EditText用户写入金额。然后，当他们转到下一个Activity时显示的数量与其他TextViews。

这是Button：

/** Called when the user clicks the Deposit button */
public void bnkDepBtn(View view) {
    Intent intent = new Intent(BankDeposit.this, BankDepositConfirm.class);
    EditText editText = (EditText) findViewById(R.id.bnk_dep_amount);
    String DepAmount = editText.getText().toString();
    intent.putExtra(EXTRA_MESSAGE, DepAmount);
    startActivity(intent);
    finish();
}

然后这是下一个Activity

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.widget.TextView;

public class BankDepositConfirm extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_bank_deposit_confirm);

    // Get the message from the intent
    Intent intent = getIntent();
    String DepAmount = intent.getStringExtra(BankDeposit.EXTRA_MESSAGE);

}

这是我要添加的xml

<TextView
    android:id="@+id/bnk_dep_con_title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:text="@string/bank_dep_title" />

<TextView
    android:id="@+id/bnk_dep_con_txt"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:layout_below="@+id/bnk_dep_con_title"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="35dp"
    android:text="@string/bank_dep_con_text" />

<TextView
    android:id="@+id/bnk_dep_con_txt2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:layout_below="@+id/bnk_dep_con_txt"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="5dp"
    android:text="@string/DepAmount" />

</RelativeLayout>

问题是

我无法让文字显示在应用中。如何使用新EXTRA_MESSAGE中的Activity数据，例如调用String。

Answer 1

你只是得到这样的价值......

   String DepAmount = getIntent().getStringExtra(EXTRA_MESSAGE//Content);
   TextView textview = (TextView) findviewByid(value);
   textview.setText(DepAmount );

Answer 2

在名为class的意图中使用它：

String a=getIntent().getExtras().getString(EXTRA_MESSAGE);
TextView tName = (TextView) findViewById(R.id.prev_pad_textView1);
tName.setText(a);

添加和意图TextView
