android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<EditText
android:id="@+id/et_number"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="phone"
android:hint="@string/defaul_prop">
<requestFocus />
</EditText>
<Button
android:id="@+id/btn_dail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="@+id/et_number"
android:text="@string/dail" />
</RelativeLayout>
三、写java代码
3.1、MainActivity.java
-
package com.pb.dial;
import android.net.Uri;
-
import android.os.Bundle;
import android.view.View;
-
import android.view.View.OnClickListener;
import android.widget.Button;
-
import android.widget.EditText;
import android.app.Activity;
-
import android.content.Intent;
public class MainActivity extends Activity {
-
@Override
protected void onCreate(Bundle savedInstanceState) {
-
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
-
//根据ID找到ID，拔号按键的ID
Button bt_dail= (Button) findViewById(R.id.btn_dail);
