我知道有很多线程针对这个问题,但没有任何解决方案可以帮助我。
我遇到了以下问题:
我希望我的按钮在开始屏幕上使用我的主要活动中的方法,该方法将TextField中的数据放入Intent并使用该Intent启动一个新的Activity。相同的代码在Android Studio上的工作方式确实有效,但在Eclipse上却没有。没有错误或任何东西,LogCat只给我这个:
06-20 14:08:39.003:D / AudioFlinger(1199):调音台(0xb44c0000)节气门结束:节气门时间(68)
我在我的acitivity_main.xml文件中定义了Button,如下所示:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
android:orientation="vertical"
tools:context="com.example.jule.bachelorapp.MainActivity">
<EditText
android:id="@+id/edit_standort"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="@string/edit_standort"/>
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="@string/edit_zeit"/>
<Button
android:id="@+id/button_sendData"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/button_sendData"
android:onClick="viewAdress"
/>
</LinearLayout>
我的MainActivity.java 文件如下所示:
package com.example.bachelorapp;
import com.example.bachelorapp.R;
import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void viewAdress(View view){
EditText editText = (EditText) findViewById(R.id.edit_standort);
String adresse = editText.getText().toString();
Uri mapIntentUri = Uri.parse("geo:0,0?q="+ Uri.encode(adresse));
Intent mapIntent = new Intent(Intent.ACTION_VIEW, mapIntentUri);
mapIntent.setPackage("com.google.android.apps.maps");
if(mapIntent.resolveActivity(getPackageManager()) != null){
startActivity(mapIntent);
}
}
}
Acitivty我想在按下按钮后打开我的MapActivity.java:
package com.example.bachelorapp;
import android.support.v4.app.FragmentActivity;
import android.annotation.SuppressLint;
import android.os.Bundle;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
public class MapActivity extends FragmentActivity implements OnMapReadyCallback {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
MapFragment mapFragment = (MapFragment) getFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
/**
* Manipulates the map once available.
* This callback is triggered when the map is ready to be used.
* This is where we can add markers or lines, add listeners or move the camera. In this case,
* we just add a marker near Sydney, Australia.
* If Google Play services is not installed on the device, the user will be prompted to install
* it inside the SupportMapFragment. This method will only be triggered once the user has
* installed Google Play services and returned to the app.
*/
@Override
public void onMapReady(GoogleMap map) {
LatLng adress = new LatLng(48.362206, 10.908704);
map.addMarker(new MarkerOptions()
.position(adress)
.title("Zuhause"));
}
}
有谁知道,为什么带有android:onClick的按钮没有反应?
我希望你能帮助我,

如果你想将EditText中的文本传递给Activity,你可以这样做。
public void viewAdress(View view) {
Intent mapIntent = new Intent(this, MapActivity.class);
//Place string as putExtra or place inside a bundle
mapIntent.putExtra("editTextString", editText.getText().toString());
startActivity(mapIntent);
}

这可能会帮助您完成所需的一些构造, https://developer.xamarin.com/recipes/android/fundamentals/intent/launch_the_map_application/

您应该设置您的活动包名称,而不是mapIntent.setPackage("com.google.android.apps.maps")
此调用您尚未在设备或模拟器上安装的谷歌地图。

<Button
android:layout_width="150dip"
android:id="@+id/button1"
android:layout_height="50dip"
android:text="@string/login"
android:layout_marginRight="10dip">
</Button>
你必须拨打按钮 - &gt; findViewById()
Button buttonOne = (Button) findViewById(R.id.button1);
buttonOne.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
//Do stuff here
}
});
