StarActivityForResult（），导致强制关闭在返回意向数据
问题描述：
这里是我的代码段：StarActivityForResult（），导致强制关闭在返回意向数据
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_settings:
startActivityForResult(new Intent(MainActivity.this,Settings.class),1);
break;
}
return true;
}
@Override
public void onActivityResult(int requestCode,int resultCode,Intent data) {
Toast.makeText(getBaseContext(),requestCode, Toast.LENGTH_SHORT); // This was causing the error. See the fantastic answer that's been provided for details. Comment out this this and it works !
if(requestCode==1) {
if(resultCode==RESULT_OK)
{
String extraData=data.getData().toString();
minD=Integer.parseInt(extraData);
Toast.makeText(getBaseContext(),minD, Toast.LENGTH_SHORT);
}
}
}
下面是Settings.java
package com.example.com.draft1;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class Settings extends Activity {
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.settings);
Button setbtn = (Button) findViewById(R.id.SetminDistance);
setbtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Intent data=new Intent();
EditText mind=(EditText) findViewById(R.id.minDistance);
String minDis =mind.getText().toString();
Intent data = new Intent();
data.setData(Uri.parse(minDis));
Toast.makeText(getBaseContext(), minDis, Toast.LENGTH_SHORT).show();
// intent.putExtra("minD", minDis);
if (getParent() == null) {
setResult(RESULT_OK, data);
} else {
getParent().setResult(RESULT_OK, data);
}
finish();
/* setResult(RESULT_OK, data);
finish();*/
}
});
}
}
现在的代码时，我选择的菜单选项设置，所需的活动打开完美，但是，当我试图返回数据时，它导致一个力量关闭

为什么我遇到强制关闭吗？
我真的很感激帮助这里的问题
按照建议
if(requestCode==1) {
if(resultCode==RESULT_OK)
{
//String extraData=data.getData().toString();
//minD=Integer.parseInt(extraData);
Toast.makeText(getBaseContext(),String.valueOf(requestCode), Toast.LENGTH_SHORT).show();
}
答
如果你看到Toast.makeText
public static Toast makeText (Context context, int resId, int duration)
所以利息
谢谢如果你给第二参数作为int然后系统会查找此ID在R.java但具有讽刺意味的是其实你想打印的数量，以便只投你的第二个参数String即this
public static Toast makeText (Context context, CharSequence text, int duration)
变化吐司行代码
Toast.makeText(getBaseContext(),requestCode+"", Toast.LENGTH_SHORT).show();
或
Toast.makeText(getBaseContext(),String.valueOf(requestCode), Toast.LENGTH_SHORT).show();
答
你应该使用，而不是URI mIntent.putExtra ... 检查这个鳕鱼Ë....
MainActivity.java
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_settings:
startActivityForResult(new Intent(MainActivity.this, Settings.class), 1);
break;
}
return true;
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if (resultCode == RESULT_OK) {
minD = Integer.parseInt(data.getStringExtra("data"));
Toast.makeText(MainActivity.this, String.valueOf(minD), Toast.LENGTH_SHORT);
}
}
}`
Setting.java
public class Settings extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.settings);
Button setbtn = (Button) findViewById(R.id.SetminDistance);
setbtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
EditText mind = (EditText) findViewById(R.id.minDistance);
Intent data = getIntent();
data.putExtra("data", mind.getText().toString());
Toast.makeText(getBaseContext(), mind.getText().toString(), Toast.LENGTH_SHORT).show();
if (getParent() == null) {
setResult(RESULT_OK, data);
} else {
getParent().setResult(RESULT_OK, data);
}
finish();
}
});
}
}

@Keyser感谢您的回复。你能解释一下吗？我是新来的机器人，因此我在理解Logcat条目时遇到了一些困难。 – Anant
对不起，不能给你更多的东西，但这就是力量关闭的原因。查看所有的字符串资源代码。 – keyser
