我需要在我的应用程序中调用此函数两次,指向两个不同的活动。我为每次通话都有一个唯一的请求代码,但是每次启动第二次活动时,我的应用似乎都会崩溃。
这是我的代码(仅相关部分): MainActivity:
ifconfig
EditMarkerActivity:
//Request Info vars
static final int GET_DETAILS = 1;
static final int EDIT_DETAILS = 2;
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
public void onMapClick(LatLng latLng) {
lat = latLng.latitude;
lon = latLng.longitude;
startActivityForResult(new Intent(MapsActivity.this,NewMarkerActivity.class), GET_DETAILS);
}
});
mMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {
@Override
public void onInfoWindowClick(Marker marker) {
current_marker = marker;
startActivityForResult(new Intent(MapsActivity.this,EditMarkerActivity.class), EDIT_DETAILS);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
if (requestCode == GET_DETAILS) {
if (resultCode == RESULT_OK) {
String marker_title=data.getStringExtra("title");
String marker_snippet = data.getStringExtra("snippet");
addMarker(lat, lon, marker_title, marker_snippet);
mMap.animateCamera(CameraUpdateFactory.newLatLng(new LatLng(lat, lon)));
}
} if (requestCode == EDIT_DETAILS) {
if (resultCode == RESULT_OK) {
String marker_title=data.getStringExtra("title");
String marker_snippet = data.getStringExtra("snippet");
current_marker.setTitle(marker_title);
current_marker.setSnippet(marker_snippet);
}
}
}
NewMarkerActivity:
public class EditMarkerActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_marker_activity);
Button save_btn = (Button)findViewById(R.id.btn_save);
save_btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
EditText editName = (EditText)findViewById(R.id.editName);
String marker_title = editName.getText().toString();
EditText editSnippet = (EditText)findViewById(R.id.editSnippet);
String marker_snippet = editSnippet.getText().toString();
Intent _result = new Intent();
_result.putExtra("title", marker_title);
_result.putExtra("snippet", marker_snippet);
setResult(Activity.RESULT_OK, _result);
finish();
}
});
}
}
有任何明显的问题吗?非常感谢帮助或洞察这个问题:)
这是Logcat的输出:
public class NewMarkerActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_marker_activity);
Button save_btn = (Button)findViewById(R.id.btn_save);
save_btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
EditText editName = (EditText)findViewById(R.id.editName);
String marker_title = editName.getText().toString();
EditText editSnippet = (EditText)findViewById(R.id.editSnippet);
String marker_snippet = editSnippet.getText().toString();
Intent _result = new Intent();
_result.putExtra("title", marker_title);
_result.putExtra("snippet", marker_snippet);
setResult(Activity.RESULT_OK, _result);
finish();
}
});
}
}
答案 0 :(得分:0)
原来问题是我没有在清单文件中定义活动。 亲爱的老我,现在我知道检查我的错误!
再次感谢大家,案件已经结案。
