1.创建Crime实体类
package com.criminalintent;
import java.util.UUID;
/**
* Created by yeeson on 2015/11/24.
*/
public class Crime {
private UUID uuid;
private String title;
public Crime(){
uuid=UUID.randomUUID();
}
public UUID getUuid() {
return uuid;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
package com.criminalintent;
import java.util.UUID;
/**
* Created by yeeson on 2015/11/24.
*/
public class Crime {
private UUID uuid;
private String title;
public Crime(){
uuid=UUID.randomUUID();
}
public UUID getUuid() {
return uuid;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
2.定义容器视图activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/fragmentContainer"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/fragmentContainer"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
3.定义CrimeFragment的布局视图
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:id="@+id/crime_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/crime_title_hint"/>
</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:id="@+id/crime_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/crime_title_hint"/>
</LinearLayout>
4.创建CrimeFragment类
package com.criminalintent;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
/**
* Created by yeeson on 2015/11/24.
*/
public class CrimeFragment extends Fragment {
private Crime crime;
TextView titleFiled;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
crime=new Crime();
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.fragment_crime,container,false);
titleFiled= (TextView) view.findViewById(R.id.crime_title);
titleFiled.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
crime.setTitle(charSequence.toString());
}
@Override
public void afterTextChanged(Editable editable) {
}
});
return view;
}
}
package com.criminalintent;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
/**
* Created by yeeson on 2015/11/24.
*/
public class CrimeFragment extends Fragment {
private Crime crime;
TextView titleFiled;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
crime=new Crime();
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.fragment_crime,container,false);
titleFiled= (TextView) view.findViewById(R.id.crime_title);
titleFiled.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
crime.setTitle(charSequence.toString());
}
@Override
public void afterTextChanged(Editable editable) {
}
});
return view;
}
}
5.在MainActivity 中动态添加CrimeFragment
package com.criminalintent;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager fm=getSupportFragmentManager();
Fragment fragment=fm.findFragmentById(R.id.fragmentContainer);
if(fragment==null){
fragment=new CrimeFragment();
fm.beginTransaction()
.add(R.id.fragmentContainer, fragment)
.commit();
}
}
}
package com.criminalintent;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager fm=getSupportFragmentManager();
Fragment fragment=fm.findFragmentById(R.id.fragmentContainer);
if(fragment==null){
fragment=new CrimeFragment();
fm.beginTransaction()
.add(R.id.fragmentContainer, fragment)
.commit();
}
}
}
最后在模拟其中运行效果如下：
