问题描述

使用Provider传输数据时程序强制Finish

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button addData = (Button) findViewById(R.id.add_data);
addData.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Uri uri = Uri.parse(""content://com.example.databasetest.provider/book"");
ContentValues values = new ContentValues();
values.put(""name""A Clash of Kings"");
values.put(""author""George Martin"");
values.put(""pages"" 1040);
values.put(""price"" 22.85);
Uri newUri = getContentResolver().insert(uri values);
newId = newUri.getPathSegments().get(1);
}
});

            public class MyDatabaseHelper extends SQLiteOpenHelper {public static final String CREATE_BOOK = ""create table Book(""        + ""id integer primary key autoincrement        + ""author text        + ""price real        + ""pages integer        + ""name text)"";                    public class MyDatabaseHelper extends SQLiteOpenHelper {public static final String CREATE_BOOK = ""create table Book(""        + ""id integer primary key autoincrement        + ""author text        + ""price real        + ""pages integer        + ""name text)"";

解决方案

把错误日志贴出来啊，这样看不出来
