我遇到了一个无法从活动中回拨的问题。将表单活动1输入到活动2但不能返回。这是我的代码:
活动1:
OnClickListener changeTextOnClickListener = new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), Setting.class);
startActivityForResult(intent, CHANGETEXT);
}
和
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
switch (requestCode) {
case CHANGETEXT:
Bundle b = data.getExtras();
this.Text = b.getString("Text");
}
}
}
活动2:
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Bundle b = new Bundle();
Intent intent = new Intent();
newText.setText(newText.getText().toString());
Toast.makeText(getApplicationContext(),
newText.getText().toString(), Toast.LENGTH_LONG).show();
b.putString("Text", newText.getText().toString());
intent.putExtras(b);
setResult(RESULT_OK, intent);
finish();
}
谁能告诉我哪里出错了?万分感谢。
清单:
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.shotboxv3.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.example.shotboxv3.Setting"
android:label="@string/app_name" >
</activity>
</application>
答案 0 :(得分:0)
由于它是实现OnClickListener的Activity,因此在Activity 2的onCreate中,您需要将要单击的按钮的侦听器设置为它所在的Activity:
myButton.setOnClickListener(this);
